Explain the status quo and development trend of research and development at home and abroad, and explore the prospects and market demand for expanding the scope of application pa12 gf30.
2.2 cyclohexanone method
The cyclohexanone, hydrogen peroxide and ammonia are reacted under normal temperature and pressure under the catalysis of cerium salt to form dicyclohexylamine peroxide (P X A). In this process, the reaction conditions are mild, and a multi-tank series reactor with stirring is used. During the reaction, the amount of hydrogen peroxide and ammonia water is increased to facilitate the reaction to the product.
The feed ratio is cyclohexanone 'hydrogen peroxide two 1:0.6 5 and the ammonia amount is 4 to 10 times that of cyclohexanone, whereby high conversion can be obtained. The whole reaction adopts automatic control, so that the gaseous ammonia is absorbed by water to prepare concentrated ammonia water as raw material, which can make the mother liquor recycle, reduce ammonia consumption and reduce “three wastes” pollution.
