甲基氰

Methods Activate GAMP with cyanogens bromide and prepare GAMP-protein conjugates using ADH as a linker and EDAC as a coupling agent. Immunize mice with the conjugates and determine the antibodies against GAMP and carrier proteins in their sera as well as the bactericidal activity of antibody against GAMP.

There have been situations when large amounts of pollutants, combined with particular meteorological conditions, have led to large numbers of directly attributable deaths: for example, in Bhopal, India, in December 1984, a release of methyl isocyanate from a pesticide plant killed about 2500 people.

这样的情况经常发生。在特殊气象条件下的大量污染物直接导致了死亡。例如，1984年12月，在印度，植物杀虫剂释放出来的甲基异氰酸盐导致了2500多人的死亡。

Sulfuric acid, methyl isobutyl ketone, glycol ether, mesitylene, II Sim resin, melamine.

硫酸、甲基异丁基酮、乙二醇丁醚、三甲苯、二辛脂、三聚氰胺。

Methacrylic Acid is one of the most important organic materials, and there is large demand indomestic and international market. The traditional preparation method of MAA has lots of limitation suchas high cost, huge pollution, and virulent raw materials. So its necessary to search a new green route toreplace the ACH route.

甲基丙烯酸是一种重要的有机化工原料，目前国内外对MAA的需求量很大，而传统的丙酮氰醇法制备MAA存在成本高、环境污染大、原料剧毒等缺点，所以需要寻找一条新的绿色工艺路线代替传统工艺。

Hindered amine light stabilizer of Cyasorb UV-3346 was synthesized in total yield of 60% by three steps from cyanuric chloride,morpholine and N,N′-bis-(2,2,6,6-tetramethyl-4-piperidinyl)-1,6-hexanediamine as starting materials.

以三聚氯氰、吗啉和N，N′-二(2，2，6，6-四甲基-4-哌啶基)-1，6-己二胺为原料用3步法合成得到受阻胺类光稳定剂Cyasorb UV-3346，总收率为60%。

Curing reactions of BPF/R EP system containing dicyandiamide were studied with differential scanning calorimetry,and the curing systems and curing condition were studied systematically with 2-ethyl-4-methyl imidazole(2E4MZ) accelerating dicyandiamide,which affected the property of BPF/resorcin copolymeriza.

通过差示扫描量热法研究了2-乙基-4-甲基咪唑对双氰胺-双酚F/间苯二酚共聚型环氧树脂体系固化反应的促进作用，并系统地探讨了固化体系及固化条件对固化物性能的影响。

Though the result was not so good, a general understanding of the problems lying in the manufacture process of the device was gotten.We found the symmetry was destroyed or decreased in the crystal structure of symmetrical star-shaped molecules, such as tetra(4-cyanophenoxymethyl-methane, tetra(N-pyrrolemethyl)methane, and a center of charility was self-formed.

本文发现，原本高度对称的星状分子，在晶体结构中，分子对称性破坏或降低，表现为手性分子；以四(4-氰基苯氧基甲基)甲烷为例，从分子间氢键作用的角度，解释了该现象形成的原因。

We found the symmetry was destroyed or decreased in the crystal structure of symmetrical star-shaped molecules, such as tetra (4-cyanophenoxy methyl -methane, tetra (N-pyrrolemethyl) methane, and a center of charility was self-formed. The phenomena was discussed by analyzing the intermolecular hydrogen-bonding interactions of tetra (4-cyanophenoxy methyl -methane.
