Description of Cyclohexanone

Cyclohexanone is the organic compound with the formula (CH2)5CO. The molecule consists of six-carbon cyclic molecule with a ketone functional group. This colorless oil has an odor reminiscent of peardrop sweets as well as acetone. Over time, samples assume a yellow color due to oxidation. Cyclohexanone is slightly soluble in water and miscible with common organic solvents. Billions of kilograms are produced annually, mainly as a precursor to nylon.

What is Cyclohexanone?

With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Cyclohexanone which has developed particularly rapidly in recent years. Do you know about Cyclohexanone?


The official answer: Cyclohexanone is an organic compound with the chemical formula C6H10O, a saturated cyclic ketone with carbonyl carbon atoms included in a six-membered ring. Colorless transparent liquid with an earthy smell, and a minty smell when it contains traces of phenol. Impurity is light yellow, with the storage time to generate impurities and color development, water-white to grayish-yellow, with a strong pungent odor. Mixed with air explosion pole and open-chain saturated ketone same. In industry, it is mainly used as raw materials for organic synthesis and solvents, for example, it can dissolve cellulose nitrate, paint, paint, etc.

On October 27, 2017, the World Health Organization’s International Agency for Research on Cancer published a preliminary list of carcinogens for reference, cyclohexanone in the list of carcinogens in category 3.

What’s the application of Cyclohexanone?

Cyclohexanone is an important chemical raw material and is a major intermediate in the manufacture of nylon, caprolactam, and adipic acid. It is also an important industrial solvent, such as for paints, especially for those containing nitrocellulose, vinyl chloride polymers, and their copolymers or methacrylate polymer paints, etc. It is used as an excellent solvent for pesticides such as organophosphorus insecticide and many analogs, as a solvent for dyes, as a viscous solvent for piston-type aviation lubricants, and as a solvent for grease, wax, and rubber. It is also used as an equalizer for dyeing and fading silk, a degreasing agent for polishing metal, and lacquer for wood coloring. Used as a high boiling point solvent for nail polish and other cosmetics. It is usually formulated with low boiling point solvents and medium boiling point solvents to form mixed solvents to obtain a suitable evaporation rate and viscosity. Cyclohexanone is a very widely used petrochemical raw material, but also an important organic solvent, cyclohexanone according to its use is often divided into two categories: amide and non-amide. Cyclohexanone for amides is mainly used to manufacture caprolactam and adipic acid, both of which are important raw materials for the manufacture of fiber PA6 and engineering plastic PA66. At the same time, cyclohexanone is an important industrial solvent and can also be used to produce pharmaceutical intermediates. At present, there are three main production methods of cyclohexanone: cyclohexane oxidation, phenol hydrogenation, and cyclohexene hydration. Phenol hydrogenation was the first process applied to the industrial production of cyclohexanone, and Chemicalbook has two oxidation routes for cyclohexane oxidation in industrial production, one for catalytic oxidation and the other for non-catalytic oxidation. The catalytic oxidation process mainly uses cobalt salts, boric acid, or metaboric acid as catalysts. 1980s Japan Asahi Kasei developed the cyclohexene hydration process for cyclohexanol. This process is based on the incomplete hydrogenation reaction of benzene as raw material to prepare cyclohexene, and cyclohexene hydration to produce cyclohexanol, with cyclohexane as a by-product in the route. The process has low consumption and effectively avoids the waste alkali generated during the cyclohexane oxidation process, which reduces the environmental pressure and has obvious prospects.

Peter has been my partner for many years, we met at the Shanghai CPHI Fair in 2014, for the first time I didn't have much interest in Peter's products because our company had a stable supplier. Although we didn't work together, Peter would often send me important news and interesting trend information about the industry, so we became good friends, even though I didn't place any orders with him during this time, even if it was a sample order. In September 2016, our original supplier was unable to provide us with the quality and delivery guarantees we needed, so I first thought of Peter and his company. Until now, we have maintained a very good personal friendship in addition to a steady business relationship.

In all my years of sourcing from China, I first time to found that working with Sincere Chemical was so good, they helped me with all the production and delivery as well as a lot of technical expertise, which saved me a lot of time. When I first approached Peter for a quotation for Optical Brightener, he made me a detailed quotation with not only prices but also foreign trade details, company profile, company strengths, R&D capabilities, production capacity, packaging methods, raw material control, environmental protection, and much more. This information was a very important reference for me in making purchasing decisions. Sincere Chemical is a trustworthy supplier and I believe our business will grow from strength to strength!

Hi, I'm Kim, I'm Peter's partner and although I don't like him very much (because he never gives me more money for my prices, hahaha) I'm still willing to write him customer feedback. As an international buyer, I have to deal with a lot of things every day and my inbox is often full of development letters. It's a lot of junk and meaningless pleasantries, which I don't like that much, but Peter's emails always give me a better understanding of the product and the industry. I am also very pleased with his work ethic, and I am very happy with his work every time I work with him, not only in providing quotations but also in facilitating all the details of my work so that I can concentrate more on other things, so he is the best supplier for me. Although his prices are not the lowest among all suppliers, his products give me the greatest peace of mind.
