Azepan-2-One Price Trend

On January 17th, the average domestic ex-factory price of liquid azepan-2-one or caprolactam (CPL) was 14,100 RMB/MT, whereas on January 24th, it was 14,075 RMB/MT. Raw material prices climbed at first, then reduced, and cost help was enhanced. The 450,000-ton-per-year Baling Hengyi CPL liquid facility was successfully run at a price of 14,400 RMB/MT.

As the price of crude oil rose around the world, so did the price of raw benzene. Due to tremendous cost pressure, azepan-2-one companies were losing money, and manufacturers raised prices one after the other. Sinopec's premium azepan-2-one prices were 14,600 RMB/MT in March.

Production Processes:

  • Production of Azepan-2-one from Buckmann Rearrangement Process; from Benzene; from Cyclohexane

Using Buckmann Rearrangement process, cyclohexanone is reacted with hydroxylamine sulphate, and is converted into cyclohexanone oxime. The produced cyclohexanone oxime is then treated with sulphuric acid, which causes Beckmann rearrangement to produce caprolactam bisulphate salt. This is followed by the neutralisation of the caprolactam bisulphate salt with ammonia to cogenerate ammonium sulphate and, finally, caprolactam.
