Study on mesophase pitch derived from 1 tetramethylbenzene

均 四 甲苯 合成中间相沥青的研究

The aromatic oligomers coupling with methylene bridge principally di tri and tetramers were synthesized from 1 tetramethylbenzene by a protonic acid as the catalyst and with trioxymethylene as the cross linking agent .

以均 四 甲苯为原料， 三聚甲醛为交联剂，在质子酸催化 作用下合成以亚甲基桥连接的齐聚芳烃化合物，在本工艺 条件下主要形成二、三、四聚体。
