Abstract:Antioxidant 1,1'-thiobis (2-naphthol) was prepared from 2-naphthol and sulfur dichloride in the mixture solvent of toluene and Ethyl acetate.The optimal synthetic conditions were as follows: the complex solvent which is a mixture of toluene and ethyl acetate in the weight ratio 3:2,the weight ratio of solvent to 2-naphthol is 8:1, the mole ratio of 2-naphthol to sulfur dichloride 2:1.03,reaction temperature 10-20℃,reaction time 3.h; The yield of 1,1 '-thiobis(2-naphthol) is over 84.7%, and the purity is more than 99.0%.
Keywords:1  1 '-thiobis(2-naphthol)  synthesis  2-naphthol  sulfur dichloride
