查询词典 acyl halide

A reaction pathway for ammonolysis of O,O-dimethylphosphorochloridothioate without catalyst was proposed,based on the reaction mechanism of acyl halide ammonolysis ,and the pseudo-homogeneous reaction kinetics were founded.

模型表明：在反应前期，O，O-二甲基硫代磷酰氯浓度对速率影响很小，反应速率呈拟一级反应特征；但在反应后期，反应速率呈明显的二级反应特征。

This paperindicated that it was good for condensation reaction when benzene-ring bearingelectron-attaching groups. It also showed that and the 6-hydroxyl group could bereacted with acyl halide, haloid ether and halo alkene, but not with halo alkane. It wasnot only the first time to find that the reaction product of D-mannitol and aromaticaldehyde is tri-condensation derivatives, but also the first time to obtain thep-phthaldehyde-sorbitol derivatives containing eight hydroxyl groups.

研究发现：苯环上有吸电子基团时对缩合反应有利；多元醇缩醛衍生物6-羟基除与酰氯反应外，也能和卤代酸酯、溴代烯反应，但不与卤代烷反应；首次发现D-甘露醇与醛反应主要得到三缩合物；首次合成了含有8个羟基的对苯二甲醛和山梨醇的缩合物。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
