金属化合物类辛烷值改进剂研究进展

Research status of octane number metallic improvers

随着汽油质量要求的提高,具有优良抗爆性能的金属化合物类高辛烷值改进剂不断发展,越来越受到关注。综述了金属化合物类高辛烷值改进剂的发展过程和研究现状。作为高辛烷值改进剂的金属组分的变化经历了由Pb、过渡金属Mn、Fe、Ni到稀土金属La、Ce再到碱金属Li、K等发展的过程;而与高辛烷值改进剂中的金属组分相结合的有机组分则由烷基、茂基、羰基发展到羧基、酚基等基团。预计今后过渡金属类汽油抗爆剂的使用会越来越少,而含有碱金属类的汽油抗爆剂会受到重视。

With the improvement of gasoline quality requirements, metallic compounds which can be used as high octane number improvers continue to develop, and is attracting more and more attention. The development and research status of the high octane number metallic improvers were summarized in this paper. Metal components of the improvers experienced the development from Pb, transition metal Mn, Fe, Ni to rare earth metal La, Ce and then alkali metal Li, K, While the oaganic components combined with the metal components changed from alkyl group, cyclopentadienyl group, carbonyl group to carboxy group and phenolic group. It is predicted that the use of transition metal gasoline antiknock agents will be less and less in the future ,while alkali metal gasoline antiknock will be more widely applied.
