抗爆剂

Through research, MTBE is a good high-octane level of gasoline additives and antiknock.

通过研究，甲基叔丁基醚是一种良好的高辛烷值汽油添加剂和抗爆剂。

The auxiliaries of gasoline antiknock additive TKC were analysed by means of gas chromatography/mass spectrometry.

采用气相色谱/质谱联用技术对汽油抗爆剂 TKC的辅助剂进行了组分分析。

Capabilities using rare earth compounds as environmentally friendly gasoline antiknock s were explored.

探讨了稀土化合物用作环保汽油抗爆剂的可能性。

Under thisbackground, our team begin the research on new organometallic antiknock agents.

有学者认为以高效金属有机抗爆剂为基础的复合添加剂将是热点。

Seeking a new unleaded gasoline antiknock agent was imperative.

寻求一种新的无铅汽油抗爆剂已势在必行。

Synthesis, Characterizations and Gasoline Antiknock Properties of Transition Metal Complexes

在环保和节能的推动下，必须有更经济高效的无铅化汽油抗爆剂来满足人们对高辛烷值汽油的需求。

For leting drop qu***ty fuel plenty of normal heptane have no lead tetraethyl , Therefore be unlikely there not be the lead pollution .

因为低品质燃料多含正庚烷而不含抗爆剂四乙基铅，所以绝对不会有铅污染。

Anti-knock additive tetraethyl lead,vapor pressure,cetane number and content of aromatic hydrocarbon,ethylenes,sulfur and oxides respectively in the motor fuel are more detailedly analysed in regard to their effect on motor vehicle exhaust emission.

较为详细地分析了燃油中四乙铅抗爆剂、芳烃含量、烯烃含量、硫含量、蒸气压、十六烷值及含氧化合物等对汽车排放的影响，并简述了其发展趋势。

We have not found any reports that o-toluidine and N,N-dimethylaniline can be used as antiknock. The electrochemical properties of aromatic amine are in line with its' antidetonating quality and actual application.

而实际上采用胺类化合物作抗爆剂时，一般使用N-甲基苯胺、苯胺、邻甲苯胺及间甲苯胺，尚未见到使用对甲苯胺和N，N-二甲基苯胺的报道。

Particularly in the production of high-octane gasoline brands, alone Change processing technology and high-octane blending more difficult are generally used by adding an appropriate amount of ANTIKNOCKS solution.

如美国、欧洲就不准在无铅汽油中使用含铁燃料添加剂。非金属抗爆剂如MTBE，尽管近年来国内普遍采用，因其不能使其充分燃烧会产生致癌物而将被限量使用。
