摘　　要：介绍了一种提高汽油安定性的新过程,即采用Diels-Alder反应,在一定处理条件下在粗汽油中加入亲双烯体,将其中的双烯烃转化为稳定的大分子化合物,可有效地提高汽油安定性,方法简单易行。实验室的研究结果表明,使用适当的亲双烯体以严格控制的加入量处理过的油品溴指数明显下降,诱导期明显增长,而辛烷值等其它性能基本不受影响。A new simple method through Diels-Alder reaction for increasing the stability of gasoline stock is introduced. Dienophile was added into the gasoline stock to react with dienes and converted to more heavy and stable molecules for increasing the stability of gasoline stock at certain treating conditions. The laboratory study showed that applying proper dienophile with controlled dosage could drop the bromine number, prolong the induction period, and the octane number and other performance of the gasoline stock were unaffected.
