Abstract
2-Hydroxy-1-naphthoic acid was prepared from β-naphthol and sodium hydroxide in n-octane,and its purity was up to 98%.The effects of the reaction pressure,temperature and time on the yield of the product were investigated by orthogonal test,and the optimal conditions were obtained.Under the optimum conditions such as: reaction pressure 0.8 MPa,reaction temperature 90℃ and reaction time 8 h,the yield of the product was 82.83%.
