| Abstract: | Through analyzing the process of the neutralization and acidification, the optimum parameters were found. Under this condition, the final product showed brilliant yellow and large-grained, the purity was 98.78%, and the yield reached 80.13%, based on the reacted 2-hydroxy naphthalene. This process has been industrialized successfully. |
