Reaction Steps
0.5 parts of SOCl2 is added to 113 parts by weight of pyrocatechol-bis-[(1-methoxy)-ethyl]-ether and 55 parts by weight of pyrocatechol at 40° C. and the whole is stirred at this temperature for half an hour. It is then allowed to cool and 2 parts by volume of 25% by weight aqueous caustic soda solution is added. The product is separated and dried over sodium sulfate and the solvent is evaporated. There remains 168 parts of the abovementioned compound having a boiling point of 85° to 90° C. at 0.5 mm.
