Process for the preparation of glycidyl ethers of di-secondary alcohols with high monomer content. |
摘要 |
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) <CHEM> where R and R1 represent radicals defined in this application is described. The said process comprises the steps of: (a) reacting a di-secondary alcohol of the formula (II) <CHEM> wherein R and R<1> represent the same radicals as above 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%.
