一氯乙烷

One-pot reactions of 4 with isocyanates, triphenyl phosphine, hexachloroethane and triethylamine produced 2-anilino-5-arylidene-1-aryl-4,5-dihydroimidazo[1,2-b]-1',2',4'-triazol-4-ones 6 (or 7) in good yields.

而后用4与芳基异氰酸酯、三苯基膦、六氯乙烷和三乙胺"一锅"反应，得到4，5-二氢咪唑并[1，2-b]-1'，2'，4'-三唑-4-酮衍生物6或7。

When used as butyl rubber reaction solvent and refrigerant respectively, methyl chloride and 1,1- difluoroethane (HFC-152a) have critical requirements for their water contents.

一氯甲烷和1，1-二氟乙烷(HFC-152a)，分别作为丁基橡胶反应溶剂和制冷剂使用时，对其含水量有苛刻的要求。

With trimethyl,4-dodecylbenezyl ammonium chloride and 18-crown-6 as pase-transfer catalysts, the azidation of polyepichlorohydrin in poly and H2O were studied. The reaction discipline and mechanism were discussed. The results show that the system with trimethyl, 4-dodecylbenezyl ammonium chloride as phase transfer catalyst and PEG as medium is a safe and effective approach to glycidyl azide polymer preparation, and azidational ratio of PECH can reach 97% above within 15 h.

研究了氯化十二烷基苄基三甲基铵和18-冠－6为相转移催化剂时端羟基聚环氧氯丙烷在聚环氧乙烷和水为介质中的叠氮化反应，探讨了反应规律和反应机理，结果表明：以PECH为介质，十二烷基苄基三甲基氯化铵(TMDA-1)为相转移催化剂的反应体系，可在15h内使PECH叠氮化转化率达到97%以上，无主链断裂等副反应，是一条较为安全快速的制备叠氮粘合剂的方法。

Grafting of crotonic acid, undecylenic acid, oleic acid, and acrylic acid onto ABS was initiated by benzoyl peroxide in 1, 2-dichloroethane solution.

以过氧化二苯甲酰为引发剂，在1，2-二氯乙烷溶液中进行反式丁烯酸、10-十一烯酸、油酸、丙烯酸接枝ABS树脂。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.

这是凯特，那个是爱朗。
