Abstract
1453882 Polyglycidyl ethers HOECHST AG 17 Jan 1974 [29 Jan 1973 9 Oct 1973] 02142/74 Heading C3B Glycidyl ethers of polyhydric phenols are made by heating the phenols with excess epichlorohydrin, in the presence of a catalyst specific to such a reaction, 0À2-8% wt. water, based on the reaction medium, 0-9-1.15 equivalents solid alkali metal hydroxide MOH per phenolic OH, and 0À001-5% wt. based on phenol, of an Sn(II) compound, the process being performed in steps, similar to those of Specifications 1,329,178 and 1,277,688, in which (1) 10-90% wt. of the MOH is added, (2) the remainder of the MOH is added, and (3) the excess epichlorohydrin is distilled off, and, if saponifiable Cl remains, the glycidyl ether is dissolved in an inert solvent and dehydrochlorinated with excess alkali hydroxide solution. The water-free phase containing epichlorohydrin distilled off in stage (2) may, but need not, be returned to the reaction mixture. Sn(II) compounds are preferably stannites or compounds that can form stannites with alkalis, e.g. simple or complex Sn(II) salts, of inorganic or organic acids, many being listed; in the Examples, Sn(II) chloride or nitrate are used. The catalyst may be choline, a choline salt, or other quaternary ammonium salt; in the examples, choline chloride is used. Other optional process details are similar to those of the above Specifications. In the examples, the phenols are bisphenol A, alone or mixed with phenol novolac. The product has a low content of saponifiable chlorine, and has low intrinsic colour. Specification 1,453,881 is referred to. Use.-In compression-moulding compositions; in potting compositions; in paints and coatings.
