Patent number: 5117010Abstract: 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 BF.sub.4.sup.-, PF.sub.6.sup.-, AsF.sub.6.sup.-, SbF.sub.6.sup.-, AlF.sub.4.sup.-, TiF.sub.6.sup.2-, SiF.sub.6.sup.2-, and ZrF.sub.6.sup.2- to produce the di-secondary alcohol, which can then be subjected to glycidylation to produce a glycidyl ether, orthe reaction of an alcohol, glycol or polyol and epichlorohydrin in the presence of the foregoing catalyst, followed by ring closure employing an alkali to produce a mono- or polyglycidyl ether. The monoglycidyl ether can be further reacted with a dihydric phenol to produce a di-secondary alcohol which is then glycidylized to produce a glycidyl ether.Type: GrantFiled: August 15, 1991Date of Patent: May 26, 1992Assignee: Ciba-Geigy CorporationInventor: Chi-Wen F. Cheng
