Abstract
1277186 Monoalkyl ethers of dihydric phenols SOC DES USINES CHIMIQUES RHONEPOULENC 17 Feb 1970 [19 Feb 1969] 7660/70 Heading C2C A process for the preparation of monoethers of the unsubstituted dihydric phenols pyrocatechol, resorcinol and hydroquinone comprises reacting the dihydric phenol with an alkyl chloride having 1 to 5 carbon atoms in the presence of a carbonate or bicarbonate of an alkali metal. Amines such as di- and triethanolamine and di- and triethylamine may be employed as catalysts. The examples describe the preparation of monomethyl and monoethyl ethers.
