Abstract: An economical and environmentally advantageous process for the continuous manufacture of unsaturated polyesters, wherein the vapors formed during the polycondensation are purified, in a two-part distillation column, to a degree where the residual content of organic starting materials is less than 1.5 per cent by weight, based on the total weight of the effluent, and the unconverted starting materials are recycled to the process.

Abstract: Oximes of cycloaliphatic ketones are made by reacting the ketones with hydroxylamine or a salt thereof under an ammonia pressure above 1 atm. in an aqueous-ammoniacal medium containing an excess of ammonia of at least 50 mol. per cent per mol. of cycloaliphatic ketone. Suitable reaction conditions are a temperature of 50-100 DEG C. and a pressure of 1-10 atm. The reaction may be effected in the presence of a water-immiscible solvent, a number of which are specified. Examples are given of the manufacture of cyclododecanone oxime.
