Three methods are used to prepare molecular imprinted polymers,which include conventional bulk technique or polymerization with ultraviolet initiated in low temperature and polymerization with silica-gel as sacrificial materials. In the polymerization procedure , Sulfamethazine(SM2)and Sulfisoxazole were used as target template molecules, methacrylic acid and 4-vinylpyridine(4-VP) and acrylamide were selected as functional monomers, ethylene glycol dimethacrylate as crosslinker, azobisisobutyronitrile was used as initator.

主要工作如下：首先，以磺胺异噁唑和磺胺二甲嘧啶为模板，分别以4-乙烯基吡啶，甲基丙烯酸，丙烯酰胺为功能单体，以二甲基丙烯酸乙二醇酯为交联剂，偶氮二异丁腈为引发剂，采用了传统方法(60℃恒温水浴)、牺牲硅胶法及低温紫外光聚合法等三种方法合成了一系列的磺胺类药物印迹聚合物。

Methyl-4-aminobenzyl sulfonamide, a key intermediate for synthesis of the pharmaceutical substance Sumatriptan, was prepared throught four steps.

甲基 4 氨基苯甲基磺酰胺是一种重要的医药中间体，主要用于合成药物舒马普坦。

Carboxymethyl dimethyl sulfonium chloride as a novel aquatic feed attractant was synthesized with chloroacetic acid, methyl sulfide and in solvent free system.

And then methanesufonic acid which is colorless and oderless is obtained by the hydrolysis of methane sulfonyl chloride at 70～90℃.

以硫、硫化钠、硫酸二甲酯为起始原料制备了二甲基二硫，然后用氯气氧化二甲基二硫得甲烷磺酰氯，经水解合成了甲烷磺酸，产品无色无味。

Also, one can try acidophilus capsules, Camphor oil, Cornstarch and DMSO, also known as dimethyl sulfoxide.

此外，一可以尝试acidophilus胶囊，樟脑油，玉米淀粉和二甲基亚砜，也称为二甲基亚砜。

Using a phase equilibrium apparatus, the solubilities of anthracene and carbazole in dimethyformamide, N-methylpyrrolidinone, cyclohexanone, xylene, dichloroethane and tetrachloroethylene were determined and solubility curves were drawn, providing useful data for crude anthracene processing.

利用液固相平衡实验装置，测定了蒽和咔唑在二甲基甲酰胺、N-甲基吡咯烷酮、环己酮、二甲苯、二氯乙烷和四氯乙烯中的溶解度，并作出溶解度曲线，为粗蒽的分离和精制提供了有用数据。

Methods Naloxone was synthesized starting from oxidation of thebaine, followed by hydrogenation, acylation, cyanidation, O-demethylation, hydrolyzation and N-allylation. The alternative method of O-demethylation, methane sulfonic acid/DL-methionine and hydrobromic acid were investigated.

在以蒂巴因为原料，经氧化、氢化、酰化、氰化、去氧甲基、水解、N-烯丙基化得到纳洛酮的合成路线中，分别采用甲磺酸／DL-甲硫氨酸和氢溴酸代替三溴化硼进行去氧甲基化和后续水解反应。

The results showed that CrNaY exhibited the best sulfur removal performance, and the removal rate of 2-methyl thiophene was higher than that of thiophene.

实验结果表明，CrNaY对含噻吩和2-甲基噻吩的模型汽油的脱硫效果最好，且对2-甲基噻吩的脱除率大于噻吩脱除率。

In the mutant plant,a genecalled Lcyc is extensively methylated and thus not expressed--and thismethylated state is heritable by subsequent generations of toadflax plants.

在突变体植物中，一个叫Lcyc基因广泛甲基化，因此不能表达。这一甲基化状态在云兰属植物中是能遗传的。
