| Abstract: | In this paper, three refining processes of high purity benzoic acid by crystallization are discussed, i,e. sublimate crystallization, solution crystallization and melts crystallization. In particular, emphasis is laid on the progress of refining benzoic acid by melts crystallization methods. Then, a conclusion and an anticipation on the developing tendency of refining benzoic acid are given. |
