ABSTRACT:
Ethylene glycol monoaryl ethers useful as fragrance chemicals are obtained by ethoxylating a phenol in the presence of an alkali metal borohydride and alkali metal hydroxide and neutralizing the resulting monoethoxylated product to pH 6.5-7.5 with an aliphatic di- or polycarboxylic acid or hydroxyaliphatic carboxylic acid. Ethylene glycol monophenyl ether having a consistent mild rose odor profile and free of undesirable metallic notes is obtained by the present process.
