Abstract
PURPOSE: To obtain the titled compound useful as a raw material for 1-mercapto- 3-naphthol industrially and advantageously, by reacting a 1-halogeno-2-naphthol with a thiocyanate in an organic solvent under heating.
CONSTITUTION: A 1-halogeno-2-naphthol is reacted with a thiocyanate, e.g. ammonium thiocyanate or potassium thiocyanate, in an organic solvent, e.g. hexane, heptane, methanol or acetone, at 60W95°C, preferably 70W90°C, for 2W8hr under heating to give the aimed substance. The amoiunt of the thiocyanate is 0.8W1.25 moles, preferably 0.9W1.1 moles based on one mole 1-halogeno-2-naphthol.
EFFECT: The reaction residue is treated easily due to the absence of acetic acid, thiocyanogen, bromine, chlorine, etc., and an expensive material for the reactor is not necessary with a wide range of selction.
