硫醇

1A series ofω-alkylmercapo acid were synthesized by two methods:one involved the reaction of the appropriateω-bromoalkyl acid with mercaptide under the presence of base;the other method was used only for the long alkyl compound by the reaction ofω-alkenyl acid and alkanethiol in the presence of AIBN.

正是基于以上考虑，本论文探索了合成下沿带有硫醚官能团，而上沿带有偶氮官能团的杯[4]芳烃衍生物的方法，进行了以下研究： 1采用ω-溴代羧酸和烃基硫醇在碱性条件下发生反应，或由ω-烯基羧酸和硫醇在AIBN的存在下反应，得到了ω-硫醚羧酸，使用氯化亚砜将羧酸转化为酰氯。

A series of antimony mercaptide compounds which formula are Sb 〓 and Sb S (CH〓〓COOR 〓(R represents an alkyl or aryl, aralkyl, n=0～2) have been synthesized. A new synthetic method has been invented to solve the defect of abroad patent method which has complex technological conditions and singleness intermediate compounds. A new catalyst QL-1 and preactivated antimony trioxide and other means have been used to avoid neutralizing, washing, separating and other procedures of intermediate and simplifing process flow at the same time. According to this new technique, a series of antimony mercaptides and their intermediate products have been synthesized with high yield.

The diffusion of ethanethiol in MFI and MOR was investigated by Molecular Dynamics.

采用分子动力学方法模拟计算了乙硫醇分子在MFI和MOR两种拓扑结构沸石中的动力学性质，比较了乙硫醇不同负载量和沸石晶格原子刚性和柔性两种状态下乙硫醇分子在沸石孔道中扩散系数的大小。

For the product 〓, the signal for n=2 is much smaller than that for n=1, which may due to the large steric hindrance by the ethanethiol ligands.

其原因很可能是乙硫醇分子体积比较大，所以金属离子结合第二个乙硫醇时，就有很大的空间位阻，以致比结合第一个乙硫醇要难得多，结果n=1～2之间出现明显的强度突变。

Study on removal rate of methyl mercaptan and ethanethiol by bio-trickling filter;2. The deodorizing effect of tea functional ingredients on methyl mercaptan (CH3SH) was studied in this investigation.

The topology models of MFIand MOR were built and the method of Configurational-bias Monte Carlosimulation was used for investigating the adsorption and distributions of ethanethiolas adsorbate in MFI and MOR type zeolites. The diffusion of ethanethiol in MFI andMOR type zeolites was studied by molecular dynamics simulation.The results show, the concentration of Zn2+ is the most important factor of theloading quantity of zeolite 13X and alumina, and the temperature secondly. The pHvalue which range from 2 to 3 effects on the loading quantity faintly.

构建了MFI 和 MOR 两种拓扑结构沸石的数学模型，以乙硫醇分子作为被吸附的目标物，采用偏倚蒙特卡罗方法模拟乙硫醇在MFI和MOR沸石上的吸附行为及分子分布密度，并利用分子动力学模拟乙硫醇在这两种拓扑结构的扩散行为，为实现面向硫化物进行吸附剂的微观结构设计作初步探索。

Two major pathways exist in the reactions of Cu〓, Ag〓, Au〓 with ethanethiol clusters, one producing 〓 and the other forming〓.

实验观察到Cu〓、Ag〓、Au〓能结合的乙硫醇数目依次为1～10、1～4、1～2，说明它们与乙硫醇团簇的反应活性逐渐减小；它们与乙硫醇的反应都生成了〓，n的大小按Cu〓、Ag〓、Au〓的顺序逐渐增大，由此推测Cu〓与乙硫醇团簇反应时生成〓为主要反应通道，Au〓与乙硫醇团簇反应时生成〓为主要通道，这两种通道并存于Ag〓与乙硫醇团簇的反应中。

The catalytic transformation pathway can change to decrease the yield of hydrogen and yield methyl-contained sulfides such as methyl mercaptan, dimethyl sulfide and dimethyl disulfide, but overlarge concentration of methanol would holdback the transformation of isobutyl mercaptan. The transformation of isobutyl mercaptan was favorable if the volume ratio of methanol and benzene was 0.2.The addition of methanol assume certain effect on the catalytic cracking of di-n-butyl sulfide in solvent benzene but without changing the cracking reaction mechanism of di-n-butyl sulfide.

甲醇也可以使异丁硫醇的催化转化路径发生改变降低硫化氢的产率，生成甲硫醇、甲硫醚及二甲基二硫化物等含甲基硫化物，但甲醇的浓度过高会抑制异丁硫醇的转化，在反应体系中当甲醇的体积占到溶剂苯体积的20%时对异丁硫醇的转化较为有利；甲醇的添加对丁硫醚在溶剂苯中的催化裂化有一定影响，但没有改变丁硫醚的裂解反应历程。
