What is a acetaldoxime (acetaldehyde oxime) project report?
An acetaldoxime (acetaldehyde oxime) project report is a detailed project report for a plant that reacts acetaldehyde with hydroxylamine to make acetaldoxime, a pesticide intermediate. It sets out the process route, raw materials, machinery, approvals, project cost, means of finance, five-year projections, DSCR and break-even that a lender or investor checks before funding.
Chemical entrepreneurs use it to size the plant and raise a term loan, and agrochemical companies use it to decide whether to make the oxime themselves or buy it.
Also known as: acetaldehyde oxime project report, acetaldoxime plant DPR, acetaldoxime business plan, ethanal oxime project report.
Acetaldoxime manufacturing plant cost in India and plant economics
The sample report models a 1,800 kg per day plant on the hydroxylamine sulphate route, running 330 days a year. It starts at 60% of capacity and reaches 80% in Year 5, selling at ₹552 per kg ex-GST on a 100% oxime basis.

Term loan at 10.5% with a 6-month moratorium and 54 monthly instalments. DSCR (debt service coverage ratio) is cash available for the loan divided by the instalments due; its lowest year in the sample is 1.39. All figures are illustrative.
Acetaldoxime manufacturing process, step by step
The common batch route reacts acetaldehyde with hydroxylamine sulphate and ammonia, then distils the oxime out of the salt solution. The seven stages below are the ones costed in the sample report.
- Chilled acetaldehyde storage
Acetaldehyde boils at about 20 °C, so it is held under nitrogen in chilled tanks and dosed cold into the reactor.
- Hydroxylamine solution make-up
Hydroxylamine sulphate is dissolved in water to a set strength. The solution is acidic, which is why the vessels are glass-lined.
- Oximation
Acetaldehyde is fed at about 20–35 °C while ammonia frees the hydroxylamine and holds the pH. Brine on the jacket removes the heat of reaction.
- Azeotropic distillation
Acetaldoxime and water boil together at about 95.5 °C as an azeotrope of about 52.5% oxime. The oxime distils out of the salt solution with no solvent extraction.
- Lights removal
A second column strips leftover acetaldehyde and ammonia and returns them to the reactor. The patented route reports under 1.2% acetaldehyde and 0.25% ammonia in the product.
- Ammonium sulphate recovery
The spent liquor is mostly ammonium sulphate. It is evaporated, crystallised and centrifuged so it can be sold instead of discharged.
- Testing and drum filling
Each batch is checked by gas chromatography for oxime content and residual acetaldehyde, then filled in HDPE drums.
Hydroxylamine route or ammoximation: which process should you choose?
Two routes are in use. The older one buys hydroxylamine as a salt. Ammoximation makes it inside the reactor from ammonia and hydrogen peroxide over a titanium catalyst.
| Point | Hydroxylamine sulphate route | Ammoximation route |
|---|---|---|
| Main inputs | Acetaldehyde, hydroxylamine sulphate, ammonia | Acetaldehyde, ammonia, hydrogen peroxide, titanosilicate catalyst |
| By-product | About 1.1 kg ammonium sulphate per kg of oxime, by stoichiometry | Mainly water |
| Reported results | Close to theoretical yield in the patent example | 99% conversion and 97% selectivity in a 2013 laboratory study on a Ti-MOR catalyst |
| Plant | Glass-lined batch reactors, two columns, salt evaporator | Catalyst slurry reactor with filtration, peroxide dosing and tighter process control |
| Main cost risk | Hydroxylamine sulphate price | Catalyst life and peroxide consumption |
Why the sample uses the salt route: the equipment is standard and the chemistry is forgiving, but hydroxylamine sulphate is 66% of raw material cost in the sample. A project report should test a price rise in this one input before anything else.
Raw materials for acetaldoxime and what each kilogram needs
By stoichiometry, one kilogram of acetaldoxime takes about 0.75 kg of acetaldehyde, 1.39 kg of hydroxylamine sulphate and 0.29 kg of ammonia, before process losses. Raw materials are 55.4% of sales in the sample at Year 3 volumes.
| Raw material | Share of cost | Year 3 (₹ lakh) |
|---|---|---|
| Hydroxylamine sulphate | 66% | 839.72 |
| Acetaldehyde | 27% | 343.52 |
| Liquid ammonia | 5% | 63.62 |
| Nitrogen and process chemicals | 2% | 25.45 |
| Total | 100% | 1,272.31 |
Acetaldehyde has a flash point of about minus 38 °C and forms peroxides in air. Storage, nitrogen and safety systems belong in the raw material plan.
Machinery for an acetaldoxime plant
The reactors and the azeotropic column are the two biggest items, together ₹266.83 lakh of the ₹635.33 lakh machinery cost in the sample.
| Machine | What it does | Sample cost (₹ lakh) |
|---|---|---|
| Glass-lined oximation reactors with brine jackets | Run the reaction and remove its heat | 139.77 |
| Azeotropic distillation column with reboiler and condensers | Separates the oxime from the salt solution | 127.06 |
| Ammonium sulphate evaporator, crystalliser and centrifuge | Turns spent liquor into saleable salt | 88.95 |
| Chilled acetaldehyde storage and dosing system | Keeps the low-boiling feed cold and under nitrogen | 63.53 |
| Lights stripping column | Removes leftover acetaldehyde and ammonia | 63.53 |
| Brine chiller and cooling tower | Chilling for storage, reactors and condensers | 50.83 |
| Ammonia storage and dosing system | Feeds ammonia to set the pH | 38.12 |
| Vent scrubber and QC laboratory with gas chromatograph | Captures vapours; tests every batch | 63.54 |
| Total plant and machinery | 635.33 | |

Environmental clearance and approvals for an acetaldoxime plant
Approvals take longer than construction for this product, so plan them first. Rules below were checked in October 2026; confirm the current position with the state authorities.
| Environmental clearance | Item 5(b) of the EIA Notification, 2006, covers pesticides and pesticide-specific intermediates and is appraised as Category A. Oxime made for other uses may fall under item 5(f) synthetic organic chemicals instead |
|---|---|
| Pollution category | Organic chemicals manufacturing and technical pesticides are red category industries; consent to establish and operate from the State Pollution Control Board carries red category conditions |
| Hazardous chemicals | Acetaldehyde and ammonia are both listed in Schedule 1 of the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989; ammonia also has storage thresholds in Schedules 2 and 3 |
| Fire safety | Fire NOC for storing and handling a very low flash point liquid, as required by the state fire service |
| Business registration | Udyam (MSME) registration, GST registration and a factory licence under state rules |
Who buys acetaldoxime in India?
Most acetaldoxime goes to makers of methomyl and thiodicarb technical, who chlorinate it in the next step of their synthesis. Demand follows their production plans and the insecticide season, and buyers approve a supplier only after trial batches.
- Methomyl technical manufacturers
- Thiodicarb technical manufacturers
- Agrochemical intermediate traders
- Pharmaceutical and fine chemical units
- Export customers in pesticide supply chains
Plan for a slow first year: approval by a pesticide buyer can take several trial lots, which is why the sample assumes only 60% capacity in Year 1, rising to 80% by Year 5.
Mistakes that weaken an acetaldoxime (acetaldehyde oxime) project report
- Mixing up solution and 100% prices
The distilled product is close to half water. Pricing solution by the kilogram but costing raw materials on pure oxime overstates revenue and DSCR.
- No plan for the ammonium sulphate
The salt route gives more ammonium sulphate than oxime by weight. Without an evaporator and a buyer for the salt, the effluent load blocks the consent.
- Costing acetaldehyde like an ordinary solvent
A feed that boils at about 20 °C needs chilled, nitrogen-blanketed storage and a vent scrubber. Leaving these out under-states both capital and power cost.
- A timeline that ignores Category A appraisal
If the plant falls under item 5(b), appraisal by the central Expert Appraisal Committee adds months. Interest during construction and the start date must allow for it.

Acetaldoxime (Acetaldehyde Oxime) project report: frequently asked questions
What is the project cost of an acetaldoxime plant in India?
Our sample report models a 1,800 kg per day plant at ₹1,294 lakh, including land, building, machinery and working capital margin. As an indicative guide, a 500–1,000 kg per day batch unit may need about ₹6–9 crore and a 3–5 MT per day plant about ₹17–25 crore. Your project report works out the cost for your route, capacity and site.
Are acetaldoxime and acetaldehyde oxime the same thing?
Yes. Acetaldoxime, acetaldehyde oxime and ethanal oxime are names for the same compound, CH3CH=NOH, made by reacting acetaldehyde with hydroxylamine. It is normally a mixture of two isomers and is sold either as a purified product or as a water solution, so a quotation must state the oxime content.
What is acetaldoxime used for?
Its main commercial use is as an intermediate for the carbamate insecticides methomyl and thiodicarb, whose makers chlorinate the oxime in the next step of their synthesis. Smaller quantities go into heterocyclic and fine chemical synthesis. Demand therefore depends on a fairly small group of agrochemical buyers, which the market section of the report has to name for your region.
Which raw materials are needed to make acetaldoxime?
On the hydroxylamine route you need acetaldehyde, hydroxylamine sulphate and liquid ammonia, plus nitrogen for blanketing. By stoichiometry one kilogram of oxime takes about 0.75 kg of acetaldehyde, 1.39 kg of hydroxylamine sulphate and 0.29 kg of ammonia before losses. In our sample report hydroxylamine sulphate is 66% of raw material cost.
Is acetaldoxime manufacturing profitable?
In our illustrative sample, a 1,800 kg per day plant earns a 17% return on investment in Year 3, breaks even at 42% of capacity and pays back in about 4.1 years, with an average DSCR of 1.59. Real results depend mostly on the hydroxylamine sulphate price, the selling price agreed with pesticide buyers and how fast the plant is approved.
Does an acetaldoxime plant need environmental clearance?
Usually yes. Pesticide-specific intermediates are listed under item 5(b) of the EIA Notification, 2006, which is appraised at the central level as Category A. If the oxime is made for other uses, the authority may consider it under item 5(f) synthetic organic chemicals instead. Confirm the item with the authority before you fix the project timeline.
Is the acetaldoxime project report PDF free, and can I use it for a bank loan?
The sample PDF is free to view and download. It is an illustrative report that shows the format and depth of an NPCS report; its figures are representative and not based on a real project, so it should not be submitted to a bank. For a loan, NPCS prepares a report for your own route, capacity, location and lender.
