Aliphatic diamine sulphonate was synthesized by the reaction of ethylenediamine with sodium 2-chloroethanesulfonate.

乙二胺基乙磺酸钠是水性聚氨酯合成中重要的亲水性扩链剂，又可作为有机中间体、生化试剂应用于其它领域。

The results show that although the amount of organic sulfur did not change remarkably, the H2S evolved from the oxidized sample decreased, COS and SO2 evolved increased significantly. This indicated that the aliphatic sulphides were selectively oxidized to sulphoxide and sulphone.

结果表明，空气和HNO3氧化后，尽管煤中有机硫总量变化不大，但煤中H2S的释放量有所下降，而COS和SO2的生成量明显增加，这说明氧化作用使得煤中弱的有机硫变成S=O和SO2结构。

Both iron atoms of the binuclear unit are bridged by one oxy atom and two acetate groups. Each iron atom is also bound to facially - coordinating tridentate IDB ligand with the aliphatic nitrogen donor situated trans to theμ- oxy atom. Each iron centers is in a distorted octahedral symmetry.

每个双核单元的两个铁原子均通过一个氧原子和两个醋酸根连接，每个铁原子同时还与位于桥氧原子对位的三齿配体IDB重脂肪链上氮原子相结合，每个铁中心为一变形八面体结构。

Molybdophopsphoric Acid Catalysis in the Oxidative Cleavage of Olefins by the Hydrogen Peroxide Oxidative cleavage of the double bond could be catalyzed by H_3PMo_(12)O_(40) using H_2O_2 as oxidant, various trisubstituted olefins were oxidized to aldehydes or ketones in high yields. The system was not satisfied for electron-deficient olefins such as trans-(2-nitrovinyl) benzol or chalcone. The reaction of aliphatic olefins did not occur under the same conditions.

二、磷钼酸催化过氧化氢对烯烃的氧化断裂反应用过氧化氢(30％)作为氧化剂，磷钼酸可以催化氧化碳碳双键的断裂反应，三取代的烯烃被氧化生成醛或酮，产率较高；此体系对于缺电子烯烃如查尔酮，不饱和硝基化合物的断裂反应效果较差，脂肪族烯烃在此体系下的氧化并不发生。

Aiming at the problem of recycling scraps unsymmetrical dimethylhydrzine, eight saturated aliphatic aminimides with low melting points were synthesized after UDMH was alkylated, acidylated and dehydrogenated.

为了解决报废偏二甲肼再利用问题，使偏二甲肼经烷基化、酰基化、脱氢，合成了八种具有较低熔点的饱和脂肪族胺基酰亚胺化合物。

Polystyrene devolatilized entirely at temperatures in the vicinity of 680 K. SBR and tyre chunks showed signs of weight loss at temperatures as low as 550K (15wt% loss). This may possibly be associated with evolution of aliphatic pyrolysates of butadiene.

在温度接近680K时，聚苯乙烯完全热解，在温度550K时，丁苯橡胶和轮胎块粒出现失重迹象（15%失重率）；这可能与丁二烯的脂族热解产物的演变相关。

The present invention is suitable for the reaction for generating aldehyde by oxygenizing various alcohols which include aliphatic alcohol, ester cyclitol, aromatic alcohol and diatomic alcohol, and which have high conversion rate to alcoholic and high selectivity to aldehyde or ketone.

本发明适用于包括脂肪醇、酯环醇和芳香醇以及二元醇在内的多种醇氧化成醛和酮的反应，具有对醇的高转化率和对醛、酮的高选择性。

Refinishing should be done by trained craftsmen as they use a special chemical called Aliphatic Acrylic Polyurethane Enamel.

修补工作应由训练有素的技工，他们采用一种特殊的化学名为脂肪丙烯酸聚氨酯搪瓷。
