| Abstract: | 2-hydroxy-l-naphthoie acid was prepared from β-naphthol and sodium hydroxide in n-octane, the on the yield of 0.8MPa, reaction purity was up to 98%. The effects of the reaction pressure, temperature and time the product by orthogonal test. Under the optimum technology： reaction pressure temperature 90 ℃ and reaction time 8 h, the yield of the product was 82.83%. |
