                                     Partial phthalic anhydride (English name trimellitic anhydride), also known as 1, 2, 4 - phthalic anhydride (1,2,4-Benzenetricarboxylic anhydride); 1,3 dihydro - 1,3 - dioxo 5 different benzene and furan carboxylic acid (1,3-Dihydro-1,3-dioxo-5-isobenzofurancarboxylic acid). White to slightly yellow needle shaped crystal. Soluble in water and acetone, butanone, 2- two DMF, ethyl acetate, cyclohexanone. Soluble in ethanol. More than 90% of the product used for PVC plasticizer trimellitic acid ester two. Benzene, three, flammable and combustible, can form explosive mixture with air. Toxic, can stimulate the mucous membranes, skin, can cause allergic allergic reactions and other obstacles. The chemical formula is C9H4O5.
                                    1,2,4 trimethyl benzene anhydride as excellent heat resistance, weather resistance increase plastic raw material, its consumption also increased, in the total consumption, about 90% for PVC plasticizing agent partial trimesic acid dioctyl ester production. Used as PVC plasticizer, can improve the heat resistance, cold resistance, solvent resistance and electrical insulation properties of polyvinyl chloride. Secondly, it can be used in manufacturing polyester resin, polyimide resin, water soluble polyester resin, water soluble polyurethane resin, water soluble amino alkyd resin and senior aviation lubricating oil, power capacitor impregnating oil, pellet binder, sizing agent and smoke eliminating agent, instant binder.
                                1,2,4- can also be used as epoxy resin curing agent, the reaction activity is very high, the curing temperature of 198 degrees Celsius, with excellent mechanical properties, electrical properties and drug resistance. Suitable for epoxy casting parts and laminated products such as heat insulation.
               Tengzhou City Xiangying Analysis Technology Co., Ltd. the XiangyingGC7990plus gas chromatograph (GC), of trimellitic anhydride industry sample hydrolysis and derivatization, and qualitative analysis and theorem of derivative products by capillary chromatography system and find an accurate and practical method for the analysis of the product.
                偏苯三甲酸酐(英文名称trimellitic anhydride)又名1,2,4-苯三甲酸酐(1,2,4-Benzenetricarboxylic anhydride);1,3-二氢-1,3-二氧代-5-异苯并呋羧酸(1,3-Dihydro-1,3-dioxo-5-isobenzofurancarboxylic acid)。白色至微黄色针状晶体。溶于热水及丙酮、2-丁酮、二甲基甲酰胺、乙酸乙酯、环己酮。溶于无水乙醇。该品的90%以上用于聚氯乙烯增塑剂偏苯三酸二辛酯。偏苯三酸酐易燃、能与空气形成爆炸混合物。有毒,能刺激粘膜、皮肤,能造成过敏性变态反应等障碍。化学式为C9H4O5。
    1,2,4-苯三甲酸酐作为优良的耐热性、耐候性增塑剂的原料,其消费量也在不断增加,在总消费量中,约90%以上用于聚氯乙烯增塑剂偏苯三甲酸二辛酯的生产。用作聚氯乙烯增塑剂,能改善聚氯乙烯的耐热、耐寒、耐溶剂及电绝缘性能。其次用于制造聚酯树脂及聚酰亚胺树脂、水溶性聚酯树脂、水溶性聚氨酯树脂、水溶性氨基醇酸树脂以及高级航空润滑油、电力电容器浸渍油、粒料粘结剂、施胶剂、消烟剂、瞬时粘结剂等。
    1,2,4-苯三甲酸酐还可用作环氧树脂固化剂,反应活性很高,固化物热变形温度198℃,具有优良的机械性能、电性能和耐药品性。适用于环氧浇注件及层压制品耐热绝缘层压物等。
        滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱仪,对偏苯三甲酸酐工业样品进行水解及衍生化处理,然后采用毛细管色谱系统对衍生化产物进行了定性及定理分析,为该产品的分析找到了一种准确实用的分析方法。
