摘要: A crude olefin oxide containing high-boiling ingredients is distilled at a pH of 4 to 7 in the presence of a nonvolatile neutral or weakly basic alkali metal or alkaline earth metal salt or hydroxide to separate the olefin oxide from the high-boiling ingredients. This permits the prevention of the polymerization of the olefin oxide and its conversion to the corresponding glycol.
