Abstract

1,125,048. Vinyl acetate. DISTILLERS CO. Ltd. 24 Feb., 1967 [29 March, 1966], No. 13735/66. Heading C2C. Vinyl acetate is recovered from reaction mixtures thereof with hydrogen halide, by neutralizing or removing the hydrogen halide by the addition of an ion exchange resin prior to the subsequent distillation of the reaction mixture. A cation or anion exchange resin may be used, and the resin may be added to the distillation kettle or the mixture passed through a column of resin prior to distillation. The reaction mixture may be derived from the oxidation of ethylene in a suspension or solution containing acetate and halide ions with or without acetic acid and with a platinum group metal or compound as catalyst.
