A Study of I.E.Catalyst Regenerating Method in the Synthesis of Trioxymethylene

树脂催化剂合成 三聚 甲醛再生方法的研究

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。
