A kind of preparation method of adipaldehyde

Abstract

The present application discloses a preparation method of adipaldehyde, the preparation method comprising: oxidizing a mixed liquid containing cyclohexene and a mixed gas containing ozone under reaction conditions to obtain adipaldehyde; wherein, the The reaction conditions include using molecular sieves as catalysts to support metal oxides. The present invention uses ozone as an oxidant, and metal oxides loaded on molecular sieves as a catalyst to oxidize cyclohexene with high selectivity to produce adipaldehyde, which overcomes the disadvantages of using noble metal complexes and sodium periodate in the oxidation reaction of cyclohexene. The invention uses ozone as an oxidizing agent to selectively oxidize cyclohexene to adipaldehyde, which is a green and environmentally friendly process with high product selectivity and no three wastes. Therefore, the present invention not only has innovation, but also has economic advantages and industrial application prospects.

Description

technical field

[0001] The application relates to a preparation method of adipaldehyde, which belongs to the field of chemistry and chemical engineering. Background technique

[0002] 1,6-Adipaldehyde is an important fine chemical product. It is a quick-acting and broad-spectrum chemical sterilizer. It can not only kill most bacteria, bacterial propagules, fungi, spores and viruses quickly and efficiently, but also does not Corrosion of metal instruments and glass and plastic products, because it is harmless to the human body, it can be widely used in the disinfection and sterilization of medical equipment, food utensils, etc. In addition, adipaldehyde is also used in oil extraction, which can inhibit sulfate-reducing bacteria and increase the sulfur content of crude oil. Using sodium periodate / silica gel system to oxidize cyclohexene to prepare trans-1,2-cyclohexanediol can produce 1,6-hexanedial with high selectivity (Perfume, Fragrance and Cosmetics, 2006(6):17-20 ).
