A process for the production of glycidyl ether of an aliphatic, cycloaliphatic or araliphatic primary or secondary alcohol, comprising:

Glycidyl ether from alcohol and epichlorohydrin

A process for the production of a material having an increased molecular weight relative to the diepoxide starting material the material being either a hydroxy-terminated or an epoxy-terminated material comprising

Production of compounds

A process for the preparation of adducts by reacting an alcohol with an epoxy compound in the presence of a catalyst, which comprises reacting an alcohol of formula I ##STR1## wherein A is an aliphatic, cycloaliphatic or araliphatic radical and r is a number from 1 to 10, with a mono- or diepoxide in the equivalent ratio of 1:20 to 20:1, based on the hydroxyl and epoxy groups, in the presence of a metal complex of formula II as catalyst

Process for the preparation of adducts of epoxides and alcohols

A process for the production of a glycidyl ether of an alcohol, comprising reacting an alcohol with epichlorohydrin, in substantially the stoichiometric proportions required to produce the 1:1 adduct, in the presence, as catalyst, of a salt of perchloric acid or trifluoromethane sulphonic acid with a metal of Group IIIA of the Periodic Table of Elements (according to the IUPAC 1970 convention); and then dehydrochlorinating the product so obtained.

Production of glycidyl compounds

An epoxide resin having the formula I: ##STR1## in which R.sup.1 to R.sup.4 are the same or different and each is hydrogen or C.sub.1 -C.sub.12 alkyl; R.sup.5 to R.sup.12 are the same or different and each is C.sub.1 -C.sub.12 alkyl or alkenyl or the glycidyl residue such that at least two R.sup.5 to R.sup.12 groups are glycidyl residues; and R.sup.13 to R.sup.20 are the same or different and are hydrogen, halogen C.sub.1 -C.sub.12 alkyl or alkenyl.
