Abstract
Meta-phenoxytoluene is prepared by reacting a mixture of sodium and potassium meta-cresylates containing at least 40 mole percent of potassium meta-cresylate, with chlorobenzene in an amount of at least 1.1 mole per mole of the cresylates, under substantially anhydrous conditions, in the presence of at least 0.5 mole of meta-cresol per mole of the cresylates and from 0.01 to 0.035 mole of cuprous chloride per mole of the cresylates, at a temperature in the range from 150 DEG C to 170 DEG C. The process of the invention enables surprisingly high yields of meta-phenoxytoluene to be obtained.
