A kind of method for preparing adipaldehyde

Abstract

The present application discloses a method for preparing adipaldehyde, the preparation method comprising: oxidizing a mixed solution containing cyclohexene and a mixed gas containing ozone under reaction conditions to obtain adipaldehyde; wherein, the The reaction conditions include using a supported metal oxide as a catalyst, and the metal oxide is composed of W oxide and Mo oxide. The present invention adopts supported W, Mo double metal oxide as catalyst, highly selective oxidation of cyclohexene to produce adipaldehyde, overcomes the shortcoming of using precious metal complexes and sodium periodate in cyclohexene oxidation reaction, the present invention Ozone is used as an oxidant to selectively oxidize cyclohexene to adipaldehyde with high product selectivity.

Description

technical field

[0001] The application relates to a method for preparing 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. In addition, as a cross-linking agent, 1,6-hexanedialdehyde has the characteristics of high activity, fast reaction, large binding capacity, stable product, and strong resistance to acid, water, and enzymes...
