The volatilizing punching oil developed with isoalkane possesses excellent volatility, lubricity and anti-corrosion ability, which can apply to metalworking of aluminum fin-stock and copper tube. 以异构烷烃为基础油研制的挥发性冲压油具有优异的挥发性能、润滑性能和防腐蚀性能,可用于铝翅片和铜管的加工。
In the oil and gas wells in Sichuan Basin, the percentage of naphthenic hydrocarbon gradually decreased while the normal alkane and isoalkane increased from deep to surface. 四川盆地油气井中自深至浅,环烷烃百分组成逐渐降低,正构和异构烷烃不断增加;
Carbon distribution and content of normal alkane and isoalkane in rubber waxes are measured by using high temperature gas chromatography. 采用高温气相色谱法测定橡胶防护蜡中的正构烷烃和非正构烷烃的碳数及含量。
According to hydrocarbon series analysis, it was found that the content of aromatic hydrocarbon in retentate sample was deeply declined, while the content of alkene, isoalkane and cycloalkane was increased. 通过烃族组成分析,低硫样品中芳烃含量大大降低,烯烃、异构烷烃和环烷烃则不断增加。
