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 or H+ or a hydronium ion and X is an anion selected from the group consisting of BF4-, PF6-, AsF6-, SbF6-, AlF4-, TiF62-, SiF62- and ZrF62- to produce the di-secondary alcohol, which can then be subjected to glycidylation to produce a glycidyl ether; or the reaction of an alcohol or diol 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.
