As a precursor material for caprolactam, my country’s research and development enthusiasm for cyclohexanone oxime is high

​ ​ Cyclohexanone oxime, also known as (hydroxyimino)cyclohexane and N-cyclohexylidenehydroxylamine, has a molecular formula of C6H11NO and is an organic compound. Cyclohexanone oxime appears as white prismatic crystals and is soluble in methanol, ethanol, water and ether. Cyclohexanone oxime is an important organic synthesis intermediate and has broad application prospects in petrochemical, pharmaceutical, synthetic dyes, electronic and electrical fields.

The preparation methods of cyclohexanone oxime include hydroxylamine method and ammoxime method. The hydroxylamine method refers to first preparing hydroxylamine by using the hydroxylamine phosphate method, Rassie method and nitrogen oxide reduction method, and then adding cyclohexanone to obtain the finished product; the ammoxime method refers to using cyclohexanone, tert-butanol, hydrogen peroxide, etc. under the action of a catalyst. The raw materials react to produce the finished product. The ammonia oxime method has the advantages of simple production process, short time consumption, and low operating cost, and is the mainstream preparation method of cyclohexanone oxime in my country.

In recent years, attracted by market prospects, my country’s enthusiasm for research and development of cyclohexanone oxime has continued to rise. In June 2023, the team of Professor Wang Shuangyin of Hunan University successfully developed a method to directly electrosynthesize cyclohexanone oxime under the action of an iron catalyst using cyclohexanone and nitrogen oxides as raw materials. This method has a high yield of finished products, The finished product has the advantages of good quality, green and environmental protection, and is expected to be widely used in the production process of cyclohexanone oxime in the future.

According to the “2023-2028 China Cyclohexanone Oxime Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center , Cyclohexanone oxime is the precursor material of caprolactam, an important chemical raw material, and nylon 6 (PA6) is its end product. Compared with nylon 66, nylon 6 has the advantages of dissolution resistance, strong hygroscopicity, and good impact resistance, and has a wide range of applications. Driven by market demand, the industry prosperity of caprolactam as a nylon 6 monomer continues to increase. my country is the world’s largest caprolactam producer. In 2022, my country’s caprolactam production capacity will reach 5.719 million tons, a year-on-year increase of 5.6%. The accelerated development of downstream industries has driven the further expansion of my country’s cyclohexanone oxime market space.

Cyclohexanone oxime is a commonly used chemical intermediate with many market participants in my country, including Hubei Rishengchang New Materials Technology Co., Ltd., Nantong Runfeng Petrochemical Co., Ltd., Wuhan Haorong Biotechnology Co., Ltd., and Anhui Xingyu Chemical Co., Ltd. Company etc. At present, my country’s cyclohexanone oxime market is dominated by small and medium-sized enterprises, with low industry concentration and a lack of leading companies. As market demand grows in the future, my country’s companies with high-quality cyclohexanone oxime production capabilities will occupy a larger space in the market.

Industry analysts said that cyclohexanone oxime has broad application prospects and the industry development speed is accelerating. With the gradual release of caprolactam market demand, my country’s The production of cyclohexanone oxime will be further increased. In recent years, Chinese companies have continued to increase research on the preparation methods of cyclohexanone oxime. In the future, with technological advancement, my country’s cyclohexanone oxime industry will develop in a high-quality direction.
