Abstract: Disclosed is a zinc-imidazole complex mixed catalyst. Also disclosed are a method for preparing the zinc-imidazole complex mixed catalyst and a method for producing a methyl N-phenyl carbamate in high yield with high selectivity in the presence of the catalyst. The zinc-imidazole complex mixed catalyst can be reused due to its high reaction stability. In addition, the use of the zinc-imidazole complex mixed catalyst leads to a marked improvement in the production yield of a methyl N-phenyl carbamate with high selectivity.

Abstract: Disclosed is a method for producing glycidol by successive catalytic reactions. The method includes a series of reactions for the preparation of glycerol carbonate from glycerol and the decarboxylation of the glycerol carbonate. Specifically, the method includes i) reacting glycerol with a dialkyl carbonate to prepare glycerol carbonate, and ii) subjecting the glycerol carbonate to decarboxylation wherein a base is added as a catalyst in step i) and is allowed to react with an acid to form a metal salt after step i), and the salt is used as a catalyst in step ii). According to the method, inexpensive and easy-to-purchase acid and base catalysts can be used to produce glycidol from glycerol, a by-product of biodiesel production, as a starting material in high yield with high selectivity in a convenient, simple, and environmentally friendly way. In addition, the method eliminates the need to separate the base catalyst.
