Abstract
The present invention relates to a laurolactam preparation method and synthesis apparatus, and epoxidation and a rearrangement reaction are performed in the conversion of cyclododecene into cyclododecanone so that the preparation method can synthesize laurolactam having a higher purity with a higher selectivity and in a higher yield than a conventional preparation method.
Claims11
A laurolactam preparation method, comprising:
- a) synthesizing epoxidized cyclododecane by epoxidizing cyclododecene (CDEN) with a catalyst;
- b) synthesizing cyclododecanone by catalyzing the epoxidized cyclododecane;
- and
- c) synthesizing cyclododecanone oxime by performing ammoximation on the cyclododecanone.
