Title: Production of diphenic acid
Inventor: SAKAI SUMIKO
IPC: C07C67/00
Filed: 1985-09-05
Abstract: PURPOSE:To produce diphenic acid useful as a raw material of polyester in high purity, by oxidizing phenanthrene with a peroxide, cooling the reaction liquid spontaneously, recovering diphenic acid from the reaction liquid with a strong acid and recrystallizing with an organic solvent. CONSTITUTION:Phenanthrene is dissolved in acetic acid, added with a peroxide (e.g. peracetic acid) and an acid catalyst (e.g. sulfuric acid), made to react with hydrogen peroxide added to the system from external source and cooled spontaneously or with water to precipitate 80% of the synthesized diphenic acid. The residual 20% of diphenic acid is recovered by adding a strong acid (e.g. hydrochloric acid) to the reaction system. The recovered diphenic acid is purified by a combination of a good solvent of diphenic acid (e.g. acetone) and a non-solvent (e.g. n-hexane) to obtain diphenic acid crystal having a purity of >=99%. The purification is carried out e.g. by dissolving the recovered diphenic acid in acetone and adding n-hexane slowly to the solution.
