Abstract

PURPOSE: To obtain the titled compound which is a raw material for preparing 1-mercapto-2-naphthol without forming by-products in high yield, by reacting a reaction product between a 1-halogeno-2-naphthol and thiourea in the presence of a solvent in an aqueous solution of an alkali under heating.
CONSTITUTION: A 1-halogeno-2-naphthol is reacted with thiourea in the presence of a polar organic solvent, e.g. methanol, ethanol or dimethylformamide (DMFA), at 60W130°C, preferably 90W125°C, and the resultant reaction product is then reacted in an aqueous solution of an alkali, preferably caustic soda, caustic potash or Na2CO3, to give the aimed compound. The method is industrial and advantageous as follows: Highly corrosive thiocyanogen and 1-cyano-2-naphthol having a strong odor are not used, and the material of a reactor is easily selected. The aimed substance can be separated easily with almost no formation of sulfur as a byproduct.
