L, 2, 4 13 methyl benzene (partial mesitylene) is producing partial trimellitic anhydride (TMA) is the main raw material, trimellitic anhydride can be made into many high value-added fine chemical products. Partial three xylene isomerization can be production of mesitylene and other chemical products, trimethylbenzene by nitration, reduction of production trimethyl aniline, methyl aniline as organic dye, medicine, special adhesive and pharmaceutical intermediates, uses a very wide range.
The analysis of the Technology Co., Ltd. Tengzhou City Xiangying XiangyingGC7990plus gas chromatograph, from chromatography typical operating conditions of determination, measurement results are accurate and confirm the precision of the determination of 1,2,4-trimethylbenzene purity and hydrocarbon impurities research. Methods to recommend the bonding / cross linked glass capillary column, using the hydrogen ionization (FID) detector and the column temperature using the temperature programmed procedure.
l，2，4一三甲基苯(偏三甲苯)是生产偏苯三酸酐(偏酐)的主要原料，偏酐可以制成很多高附加值的精细化工产品。偏三甲苯异构化可生产均三甲苯等化工产品，均三甲苯经硝化、还原可生产均三甲基苯胺，均三甲基苯胺作为有机染料、医药、特种胶粘剂和医药的中间体，用途非常广泛。
滕州市翔鹰分析技术有限公司采用XiangyingGC7990plus气相色谱仪,从色谱典型操作条件的确定、测量结果准确度和精密度的确认对测定1,2,4-三甲基苯纯度及其烃类杂质进行研究。方法推荐键合/交联玻璃毛细管色谱柱,使用氢离子化(FID)检测器,柱温采用分阶的升温程序
