  摘要：

  p-Benzoquinone (1) reacts with dialkylamines 2a-d to 2-dialkylamino-p-benzoquinones 3, 2,5-bis-dialkylamino-p-benzoquinones 4, 2-dialkylamino-8-hydroxydibenzofuran-1,4-quinones 5, and in pyridine also to 2-dialkylamino-5-p-hydroxy-phenoxy-p-benzoquinones 6. A method affording almost exclusively 3 has been developed which is also applicable to compounds 2e-h.

  Described are methods and composition for inhibiting polymerization of a monomer (e.g., styrene) composition using an aminated quinone antipolymerant, such as an aminated benzoquinone or aminated naphthoquinone antipolymerant having one or more secondary or tertiary amine group(s). The aminated quinone antipolymerant can be used with little or no nitroxyl group containing antipolymerant yet still provide excellent antipolymerant activity in a monomer-containing composition.

  描述了一种使用氨基喹诺烷抗聚合剂（例如，氨基苯醌或氨基萘醌抗聚合剂）来抑制单体（例如苯乙烯）组合物的聚合的方法和组合物，该氨基喹诺烷抗聚合剂具有一个或多个次级或三级胺基团。氨基喹诺烷抗聚合剂可以与几乎不含氮氧自由基的抗聚合剂一起使用，但仍然在含单体组合物中提供出色的抗聚合活性。

  The kinetics and the volume of activation of the title reaction to form 2-dibutylamino-p-benzoquinone in 1,2-dicholoroethane and acetonitrile, –54 ± 2 and –67 ± 2 cm3/mol respectively, strongly support a reaction scheme in which ionic species are formed prior to the rate-determining step which is the second attack by the amine.

  在1,2-二氯乙烷和乙腈中分别形成–54±2和–67±2 cm 3 / mol的标题反应形成2-二丁基氨基-对苯醌的反应动力学和活化体积，强烈支持了以下反应方案在速率确定步骤之前形成哪些离子物种，这是胺的第二次攻击。
