摘　　要：介绍了间苯二甲酸(IPA)的生产技术,重点介绍了空气液相氧化法生产IPA,其工艺分3个阶段, 即粗IPA的制备,精IPA制备、母液及残渣的处理。IPA主要应用在酸改性共聚酯、不饱和聚酯及表面涂料方面。预计在今后几年中,IPA在共聚酯方面的应用将得到迅速发展。The production technologies for isophthalic acid （IPA） were introduced, emphatically air liquid phase oxidation which comprised coarse IPA preparation, purified IPA preparation and liquor and residues treatment. IPA was mainly applied in the synthesis of acid modified copolyester, unsaturated polyester and surface coating and was expected to be rapidly developing in the field of copolyester production in the following several years.
