The synthetic method was used to determine the solubility of acetyl-p-toluidine in methanol, ethanol, 1-propanol, 2-propanol, 1-butanol, isobutyl alcohol, tertbutyl alcohol, chloroform, benzene, carbon tetrachloride, diethyl ether, and water from about 35°to 148.5°C. The heat of fusion of acetyl-p-toluidine as calculated from solubility measurements was found to be 6400 cal. per mole.
