| titleOfInvention |
Manufacture of α-naphthol |
| abstract |
Process for the manufacture of α-naphthol by hydrolyzing α-naphthyl esters of aliphatic carboxylic acids in a distillation column by means of steam in counter-current at a particular temperature, and in a certain ratio, in the presence of naphtholsulfonic acids and/or sulfonic acids of naphthyl esters. The α-naphthol obtainable by the process of the invention is a valuable starting material for the manufacture of dyes, drugs and insecticides, e.g. α-naphthyl N-methylcarbamate. |
