Process for the preparation of glycidyl ethers of di-secondary alcohols
with high monomer content
摘要:
The present invention relates to a process for the preparation of a glycidyl ether of a di-secondary alcohol with a monomer content of about 80% to about 90% of the formula (I) ##STR1## comprising the steps of: (a) reacting a di-secondary alcohol of the formula (II) ##STR2## with epichlorohydrin in the presence of an alkali and a phase transfer catalyst to produce a glycidyl ether with a monomer content of about 60% to about 75%; and(b) reacting said glycidyl ether with a monomer content of about 60% to about 75% with epichlorohydrin in the presence of an alkali and benzyltrimethylammonium chloride to produce a glycidyl ether of a di-secondary alcohol with a monomer content of about 80% to about 90%.
