新型汽油抗爆剂发展研究

Research Progress on New Type of Gasoline Antiknock

简述了国内外汽油抗爆剂的发展概况,对现有常规抗爆剂进行了评述。由于金属类抗爆剂存在对机车和环境的损伤问题,认为金属类抗爆剂将逐渐退出历史的舞台,高效环保型有机抗爆剂将是今后的发展方向。结合爆震原因、抗爆机理以及过氧化物反应规律,认为抗爆剂在起到抗爆作用时,各个基团是相互独立抗爆的,我们称之为基团贡献法,在此基础上总结出了高效环保型有机抗爆剂应该具有的基本性质,并认为基于芳基的异构类化合物将可能成为高效环保型抗爆剂的主要结构。

The general situation of the development of gasoline antiknock both at home and abroad was briefly described, and the existing conventional antiknock agent were reviewed.Because of kind of antiknock damage by metal in cars and environment problems, metals antiknock would gradually withdrew from the historical stage, efficient and environmentally friendly organic antiknock agent would be the development direction in the future.Combining with the causes and mechanism of antiknock detonation, and peroxide reaction rule, it was realized that in the antiknock effect, each group was independent of anti-explosion, which was the group contribution, it was summarized that the efficient and environmentally friendly organic antiknock should had the basic nature, and multiple heterogeneous aromatic hydrocarbon based on aromatic compounds could be efficient and environmentally friendly antiknock main structure.
