摘要： To reduce the content of hydrolyzable chlorine in glycidyl compounds, these are dissolved in a halogen-free organic solvent and treated with an equivalent excess of aqueous alkali metal hydroxide solution at elevated temperature, the excess being 100 to 200% of the equivalent amount theoretically required for complete dehydrochlorination of the hydrolyzable chlorine, the water is then removed from the organic solution, the organic solution is treated with 5 to 500 times the amount, based on the amount of alkali metal hydroxide employed, of moist cellulose containing up to 35% by weight of water at elevated temperature and, after filtration, the glycidyl compound is isolated from the organic solution.

摘要： In accordance with the present invention, methods have been developed for the reduction of the chloride content of epoxy compound starting materials. Invention methods comprise subjecting specifically defined combinations comprising an epoxy resin starting material and other components to conditions sufficient to produce a treated epoxy compound (i.e., an epoxy compound having a chloride content which is reduced relative to that of the epoxy resin starting material), and separating the treated epoxy compound from the combination. Other components contemplated for use in the practice of the present invention comprise, alternatively, mixtures of crown ether, organic solvent and suitable base; mixtures of crown ether-like solvent and suitable base; mixtures of aprotic solvents and hydrides (other than tin hydride); mixtures of nonhalogenated organic solvent and reducing metal; and the like. In accordance with a further aspect of the present invention, products (i.e., treated epoxy compounds, encapsulants and fillers) are provided which have been produced by the invention methods.

摘要： Diepoxides of the general formula: ##STR1## wherein n has an average value not exceeding 0.03 and R is the bisphenyl radical of bisphenol-A are recovered from an epoxy resin of the same general formula with n varying from 0.07 to 0.30, by removing the low-boiling substance from the epoxy resin at 0.1-1 mm Hg and 165.degree.-200.degree. C and distilling off said diepoxide from the thus treated epoxy resin at 0.1-0.005 mm Hg and a temperature not exceeding 240.degree. C. The low viscosity, narrow molecular weight distribution and excellent purity of these diepoxides allow their use in critical application fields.
