    • The present invention relates to a 6-hydroxy-2-naphthoic acid manufacturing method using naphthalene and, more specifically, to a 6-hydroxy-2-naphthoic acid manufacturing method comprising: a step of manufacturing sulfated naphthalene by performing sulfating reaction on naphthalene; a step of manufacturing sulfuric acid naphthalene alkali salt by performing neutralization reaction on sulfated naphthalene; a step of manufacturing beta naphthol alkali salt by performing hydrolysis reaction on sulfuric acid naphthalene alkali salt; and a step of performing carboxylation reaction on beta naphthol alkali salt. The present invention can manufacture 6-hydroxy-2-naphthoic acids from naphthalene through a simplified process when compared to an existing process by consecutively applying beta naphthol potassium salt as a reactant of carboxylation reaction by allowing the beta naphthol potassium salt to be a product of naphthalene hydroxylation reaction.
    • 本发明涉及使用萘的6-羟基-2-萘甲酸制造方法,更具体地,涉及6-羟基-2-萘甲酸制造方法,其包括:通过对萘进行硫酸化反应来制造硫酸化萘的步骤; 通过对硫酸化萘进行中和反应制备硫酸萘碱盐的步骤; 通过对硫酸萘碱盐进行水解反应制备β萘酚碱盐的步骤; 以及对β-萘酚碱盐进行羧化反应的工序。 本发明可以通过简单的方法通过简单的方法从现有的方法制备6-羟基-2-萘甲酸,通过连续施用β-萘酚钾盐作为羧化反应的反应物,通过使β萘酚钾盐成为 萘羟基化反应。
