The alkaline methanolysis of 2 occurred in MeONa-MeOH solution, and gave the products with the inversion of configuration with PhO as a leaving group.

我们曾研究过个别硫代磷酞胺醋的酸性醇解反应'了，关于这类化合物的碱性醇解反应未见文献报道。

The research presented here is aimed at exploring the effect of DTT on the in vitro fibril formation of hen egg-white lysozymes with four disulfide bonds. In this work, we specifically addressed the effect of DTT concentration under different incubation temperatures on the hen lysozyme structure and fibril formation, the effect of addition of DTT at later time points on the amyloid fibrillization of hen lysozymes, and the effect of concentration ratio between reduced and oxidized forms of DTT on the fibril formation of lysozymes.

本研究以具有四对双硫键的母鸡蛋白溶菌酶为蛋白质模式系统，在含盐类之酸性溶液环境下诱导生成类淀粉纤维，再配合二硫代苏糖醇破坏溶菌酶中的双硫键，探讨：（1）不同温度下加入不同DTT浓度对溶菌酶类淀粉纤维形成之影响，（2）不同生长时期加入DTT对溶菌酶类淀粉纤维形成之影响，（3）不同比例之DTT和氧化态DTT浓度对溶菌酶类淀粉纤维形成之影响。

This method had been applied to determination of the optical purity of the product from asymmetric ring opening of meso- epoxides.

方法已用于非手性环氧化合物不对称开环反应产物β-氨基醇及β-羟基硫醚类化合物的光学纯度鉴定。

GC-MS analysis suggests that the second part contains phenol sour and sulfur alcohol, which best suits further purification and identification.

GC-MS分析表明，鸭粪的抑菌物质主要为酚酸类和含硫醇有机物质，进一步纯化和鉴定有待研究。

Direct enantiomeric separation of racemic mixtures of 13 β-amino alcohols and β-hydroxy sulfides was achieved by HPLC using Chiralcel OD, Chiralcel OJ and Chiralpak AD as chiral stationary phases and hexane/2-propanol mixture as eluent. These racemates were completely separated into enantiomers at least on one of these stationary phases.

在以正己烷-异丙醇为移动相的体系中，用ChiralcelOD，ChiralcelOJ及ChiralpakAD作为手性固定相对13种β-氨基醇及β-羟基硫醚类化合物对映体进行HPLC手性拆分，这些化合物至少能在一支柱上得到基线级分离。

It can be seen from Table 1 that the residual recalcitrant organics consisted of alcohols (36.68%a),phenols (6.88%),ketonnes,quinines, parafins, nitrogenous and sulfur compounds.

从表1中可见，残余的不易分解的有机物包括了酒精36.68%），长链烷醇混合物(6.88%，酮类、奎宁，石蜡，含氮和硫化合物。
