| 摘 要： | 对加有甲基环戊二烯三羰基锰抗爆剂的车用汽油见光后诱导期、辛烷值的变化进行了试验考察。试验结果表明:含锰车用汽油见光后锰抗爆剂抗爆作用丧失、诱导期急剧下降,汽油变浑浊并有沉淀生成;避光保存时,其性质在半年内不会有大的变化。对金属锰基有机化合物的抗爆作用机理及见光失效原因进行了初步分析,提出了含锰车用汽油在取样、储存及检验过程中应避光操作。对于汽油见光所引起的质量变化,应当引起有关生产、销售、监督及检验等部门的高度重视,并应加强对含锰汽油在储存、使用中发生的变化进行考察和研究。

| Abstract: | The changes of induction period and octane number of gasoline with manganese antiknock additive after exposure were investigated. The tests showed that after gasoline exposure, the antiknock function of the additive was lost; the induction period of the gasoline dropped sharply; and the gasoline became turbid and some deposit formed. When kept the gasoline in protection from light, its property had no obvious change within 6 months. The antiknock mechanism of the organic compound of manganese and the exposure effect were analyzed. It is suggested that exposure of gasoline should be avoided during sampling, storing, and testing, and the departments of production, supervision and testing should pay attention on the matter. |
