METHOD FOR PRODUCING A MONOBENZYL ETHER OF GLYCEROL AND/OR A GLYCEROL POLYMER, METHOD FOR PREVENTING YELLOWING, YELLOWING PREVENTION AGENT, AND BUCCAL COMPOSITION

摘要

Provided are a method for producing a (poly)glycerol monobenzyl ether which makes it possible to obtain a (poly)glycerol monobenzyl ether with high yield and selectivity in an etherification reaction of a benzyl alcohol and (poly)glycerol, and a method for preventing yellowing, a yellowing prevention agent and a buccal composition in which use is made of a monobenzyl ether of glycerol and/or a glycerol polymer produced by said production method. In the method for producing (poly)glycerol monobenzyl ether, a benzyl alcohol and (poly)glycerol are reacted in the presence of ZSM-5 zeolite.
