    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⁻, TiF₆²⁻, SiF₆²⁻ and ZrF₆²⁻ 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.

    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)

    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)
    wherein R and R¹ 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%.
