Abstract

In the production of olefine oxides by treating chlorhydrins with strong alkali, use is made of chlorhydrin solutions of less than 40 per cent concentration and the olefine oxides are removed as soon as formed. Preferably solutions containing less than 15 per cent chlorhydrin are employed. According to the example, a 10 per cent solution of ethylene chlorhydrin is heated to boiling with caustic soda in a kettle surmounted by a reflux condenser and the resulting ethylene oxide condensed in a cooled receiver. Propylene chlorhydrin may be similarly treated to give propylene oxide. Other alkalis such as alkaline earth hydroxides may be employed and the removal of the product may be effected under reduced pressure.
