| 摘要 |
The present invention relates to the preparation of di-secondary alcohols comprising the reaction of an alcohol and a diglycidyl ether of a dihydric phenol in the presence of a catalyst of the formula (IV): MX (IV) wherein M is a metal from Groups IB to VIIIB or a metal or metalloid from Groups IIA to VA of the Periodic Chart of Elements or an ammonium ion and X is an anion selected from the group consisting of BF4<->, PF6<->, AsF6<->, SbF6<->, AlF4<->, TiF6<2><->, SiF6<2><-> and ZrF6<2><-> to produce the di-secondary alcohol, which can then be subjected to glycidylation to produce a glycidyl ether which are characterized by low viscosity, high purity and by low easily hydrolyzable chlorine content.
