Abstract

The invention discloses a method for synthesizing cyclododecalactone by catalytic oxidation of cyclododecanone. Cyclododecalactone is synthesized by using a molybdenum-containing compound as a catalyst, cyclododecanone as a raw material, a hydrogen dioxide solution as an oxidizing agent and acetonitrile as a solvent, wherein the molybdenum-containing compound is any one selected from ammonium molybdate, sodium molybdate, sodium phosphomolybdate and molybdenum oxide. With the molybdenum-containing compound used as the catalyst, there is no waste acid treatment or strong acid corrosion, energy conservation and emission reduction are realized and safety is high; with cyclododecanone used as the raw material, no high-temperature reflux reaction is required, and economic benefit and environmental benefit are raised; and by applying the hydrogen dioxide solution as an oxidizing agent, cleanability and safety of an industrial preparation reactions are raised, and environmental pollution is reduced.

Description

technical field

[0001] The invention relates to a synthesis method of a cyclododecanolide compound, belonging to the field of organic chemical synthesis. Background technique

[0002] Cyclododecanolide is one of spices and an important monomer for the production of polymer materials. At present, the synthetic method of cyclododecanoic acid mainly uses dodecanoic acid (Teruaki, Mukaiyama et al, Chemistry Letters, 49-50, 1976), derivatives of dodecanoic acid (Haruo, Matsuyama et al, Chemistry Letters, 1931-1932, 1988) or cyclododecanone as raw material.

[0003] The method of synthesizing cyclododecanone with cyclododecanone as a raw material belongs to the category of Baeyer-Villiger oxidation reaction method. Because cyclododecanone contains a macrocyclic structure, it has special reactivity that some small rings and middle rings do not have. At present, the Baeyer-Villiger oxidation reaction is dominated by the mesocyclic cyclopentanone cyclohexanone and its derivatives. ...
