Abstract
a : b - Dihydroxy - g - (2 - hydroxyphenoxy) - propane is prepared by (1) condensing together equimolecular proportions of catechol and glycidol in the presence of a nitrogen-containing organic base; or (2) condensing catechol monoacetate with glycidol in the presence of pyridine and hydrolysing the resulting a : b -dihydroxy-g -(2-acetoxyphenoxy)-propane. In either case, the reaction is initiated by warming, and the temperature is prevented from rising above about 110 DEG C. by external cooling. In method (1), the organic base may be pyridine, picoline, quinoline, dimethylaniline, a primary amine (e.g. ethylamine) or a secondary amine (e.g. dimethylamine). In method (2), the hydrolysis may be effected by alkali, e.g. potassium hydroxide in ethyl alcohol. An example is given of each method. Specification 628,497 is referred to.
