Product Overview
Cyclohexanone, CAS 108-94-1 (EINECS 203-631-1), is an alicyclic ketone with the molecular formula C₆H₁₀O, also traded as ketohexamethylene and pimelic ketone. It arrives as a colorless to light yellow transparent liquid with a minty, acetone-like odor, and it holds two jobs in one drum: a reaction feedstock for the polyamide chain and a medium-to-high boiling solvent in its own right.
That double role is what makes it worth specifying carefully. Polymer plants take it as a clean, low-moisture feedstock for caprolactam and adipic acid. Coatings, inks, adhesive and leather-finishing plants take it as the solvent that carries resins and oils into solution and keeps a film open long enough to level. The same drum serves both, because what we ship from Shandong is a single ≥99.5% grade made by cyclohexane oxidation, with moisture and ketone-related impurities held low.
For a formulator the practical note is simple: this is a medium-to-high boiler, chosen for solvency and flow rather than for speed; unlike a fast ester such as ethyl acetate, it stays in the film longer. It pumps and meters easily at ambient temperature, which keeps day-tank and in-plant transfer work uncomplicated.

Nylon Intermediate Routes
- Oximation: cyclohexanone reacts with hydroxylamine to give cyclohexanone oxime. This is where feedstock quality is first tested — moisture and residual impurities move the oxime yield, which is why polymer buyers match the lot's moisture and impurity figures against their own feed specification before the tank is charged.
- Beckmann rearrangement: the oxime is rearranged under acid to caprolactam, the seven-membered lactam that opens into Nylon 6.
- Polymerisation: caprolactam is ring-opening polymerised into Nylon 6 fibre, film and engineering resin. Colour and melt viscosity in the finished polymer are the two properties most often traced back to what entered at the oxime stage.
- Oxidation to adipic acid: a parallel route oxidises cyclohexanone to adipic acid, the dicarboxylic acid behind Nylon 66 and a feedstock for polyurethane systems.
- Before you charge: agree the grade in advance. Ask for the lot data on fibre or resin duties early enough that the specification is settled before the container is loaded, rather than on arrival at the plant gate.
Solvent Applications
- Nitrocellulose and cellulose acetate: cyclohexanone dissolves both, which puts it into lacquers, wood coatings and cellulose-ester systems that need a slower solvent to keep the film open.
- Resins and oils: it takes a wide range of natural and synthetic resins and oils into solution, so one solvent can carry a mixed resin system without a co-solvent.
- Coatings and paints: the medium-to-high boiling profile buys flow and levelling time before the oven or the air-dry stage takes over — useful on thick films and on lines with generous flash-off zones, and often blended with a faster ester such as our ethyl acetate solvent to shorten the overall drying curve.
- Printing inks: used in ink vehicles where solvency strength counts for more than evaporation speed, and where a slower solvent helps limit skinning in the pan.
- Adhesives: contributes solvency and open time to solvent-based adhesive blends, particularly where the adhesive has to wet a difficult substrate.
- Leather processing: works as a levelling and degreasing agent in leather finishing, lifting grease from the grain and helping the finish coat sit evenly.
- Industrial cleaners: formulators use it as the strong-solvent component in degreasers and heavy-duty blends, where slower evaporation gives the surfactant package time to work on the soil.
Related Solvents From the Same Range
- Own production lines: MTBE and ethyl acetate run on our proprietary lines, so both can be quoted, documented and loaded alongside this ketone.
- Fast-drying grades: where a coating or ink needs the quick end of the evaporation range, our ethyl acetate solvent covers it from the same stock position.
- Benchmarking suppliers: buyers comparing ethyl acetate suppliers usually check the same three things — lot COA, assay consistency and a confirmed loading date — and those are the points we answer here too.
- Volume planning: wholesale ethyl acetate moves on the same container programme as cyclohexanone, so a mixed order can be planned as one shipment.
- Documents for a mixed order: one COA pack covers both products, and the SDS ethyl acetate sheet is issued with it.
- Blend sets for industrial cleaners: formulators building industrial cleaners take this ketone together with the alcohols, glycols and esters in the range, so the whole blend set can be quoted on one schedule.
Handling and Storage
With a closed-cup flash point of 44 °C, cyclohexanone is a flammable liquid and has to be managed as one. Vapour pressure is 0.5 kPa at 20 °C, so the headspace of a part-used drum carries a flammable concentration; keep bungs closed, store under cover in a cool, well-ventilated place, and keep drums away from ignition sources, hot work and direct sun.
Transfers should be bonded and grounded, with pumps, hoses and gaskets rated for ketones. Local exhaust ventilation at the point of fill keeps operator exposure down, and gloves, splash goggles and a suitable respirator belong in the written procedure for anyone opening a drum or drawing a sample.
Segregate from strong oxidisers and keep the store dry and free of standing water. Spills should be contained with inert absorbent, kept out of drains and cleaned up promptly — a thin film on a concrete floor is both a slip hazard and, in a confined space, a vapour source. Empty drums go through a licensed disposal route rather than being reused for other chemicals, because residual ketone in a closed drum stays a hazard long after the drum looks empty.
Ordering, Packing and Delivery
- Who you are buying from: we are an integrated enterprise covering R&D, production, sales, storage and logistics, running our own plants alongside long-standing partnerships with major chemical manufacturers. Buyers who first came to us as an ethyl acetate manufacturer can add this ketone to the same account without setting up a new supplier.
- Minimum order: one 20-foot container (20' FCL) per product.
- Samples: sample orders for testing are welcome. Tell your sales contact the grade and application you need and they will confirm the sample arrangement and the courier cost.
- Payment: T/T and L/C are the standard terms; other arrangements can be discussed for repeat business.
- Lead time: shipment is generally arranged within 14 working days of receiving the deposit or the original letter of credit.
- Pricing: quotes are built against order quantity, and multi-container or repeat programmes — for this product or for wholesale ethyl acetate — are negotiated individually rather than taken from a list price.
- Combined contracts: buyers who already purchase ethyl acetate from us often put this ketone on the same contract, so one schedule and one document set cover both deliveries.
- Supplier comparison: if you are still comparing ethyl acetate suppliers, ask for both quotes in the same request so the commercial terms and the documentation line up side by side.
- Packing: packing is agreed per order. The formats we handle include steel drums, plastic drums, IBC tanks, flexitanks, ISO tanks and bags — confirm the option that suits your volume, discharge point and site storage before the order is placed.
- Dispatch: orders are loaded in Shandong and shipped through the Bohai Rim gateway ports; confirm the port and terms that match your destination.

FAQ
Q1. Should I specify one grade for polymer feedstock and another for solvent work?
One grade covers both. What changes is the set of figures each buyer checks: polymer customers match moisture and impurity data against their feed specification, while formulators look at clarity, colour and how the solvent behaves in their own resin system. Tell your sales contact which duty the material is going into and the lot data will be issued for that use.
Q2. Can cyclohexanone go into industrial cleaners and degreaser blends?
Yes. It acts as the strong-solvency, slower-evaporating component in those blends, which suits heavy soils and baths worked at ambient temperature, where a fast ester would flash off before the surfactant package has done its job. Test compatibility with your surfactant and builder system in your own lab before scaling up, and allow for the ketone odour, which is more noticeable in an open bath than in a dried film.
Q3. How does it behave with water, and does the neutral acidity matter?
Solubility in water is slight, so in an aqueous stream the ketone separates rather than dissolving and phase separation stays straightforward. Neutral acidity means the product does not push acid value in a coating, ink or adhesive and will not neutralise an acid-catalysed step. Where the reaction is moisture-sensitive, ask for the water figure on the COA and keep bungs closed in store — an open drum in a humid building will pick up moisture over time.
Q4. Does the low melting point matter in cold weather?
The melting point is -47 °C, so there is no freezing or crystallisation risk in winter transit or in an unheated warehouse. Viscosity does rise as temperature drops, though — the 2.2 mPa·s figure is measured at 25 °C — so pump rates on an outdoor line will be slower on a cold morning. Check the pump curve rather than the specification sheet if throughput matters to your operation.
Q5. The boiling point looks high — will it slow my coating line down?
It can, if the oven dwell is short. At 155.6 °C it stays in the film longer than a fast ester, which is what you want for flow, levelling and adhesion on thick films, but a short flash-off zone may leave residual solvent. Most formulators blend it with a faster ester — our ethyl acetate solvent is the natural partner — and test the drying curve on their own line before committing a production batch.
