N-substituded thioacridones with five different structures were synthesized via a route involving Ull-man reaction, cyclization, N-alkylation and sulfurization. The structures of each thioacridone were identified with IR and MS. The results from UV-spectrophotometry show that the five N-alkythioacridones all have stronger absorption in the visible light region.

采用乌尔曼反应、酸催化环化、N-烷基化和硫代化四步反应路线合成了5种不同结构的N-取代硫代吖啶酮，利用IR和MS分析手段表征了其结构，UV分光光度计的测定结果表明5种硫代吖啶酮在可见光区都有较强的吸收。

Studied influence of sulphonated naphthalene formaldehyde condensates, polycarboxylic series(SR3), aminosulfonic acid-based series on rheology of sulphoaluminate cement paste. Adjusted setting time with setting retarder, and reduced water dilution, bleeding, segregation of fresh paste with viscosity-modifying admixture.

研究了萘系、氨基磺酸盐系和聚羧酸系高效减水剂与硫铝酸盐水泥的相容性问题，利用缓凝剂有效控制了硫铝酸盐水泥的凝结时间，利用浆体稳定剂成功解决了水泥净浆的板结、泌水问题，从浆体流变学角度研究了外加剂—硫铝酸盐水泥浆体体系稳定性。

The our company after relates in every way according to the above situation, already from overseas massively purchased the ZX-10 series desulphurization catalyst, has been able to coke with this catalyst technology the sulphonium compounds which the triphenyl contained, the nitrogen compound , the unsaturated compound and very many impurities, the fetid odor and so on removes, after the processing triphenyl always Sulfur content was lower than the petroleum benzene, the smell, the color, was consistent with the petroleum benzene.

目前焦化三苯在工业上使用范围小，销售价格也低于石油三苯。其主要原因是硫、噻吩等杂质含量高、气味重。而现在国际、国内焦化三苯、汽油、柴油等产品脱硫提纯去杂质的工艺均采用高压催化加氢法处理，该工艺设备投资巨大。根据以上情况我公司经多方联系，现已从国外大量购进ZX-10系列脱硫催化剂，用本催化剂技术已能将焦化三苯所含的硫化合物、氮化合物、不饱和化合物及很多杂质，臭味等脱除，处理后的三苯总硫含量低于石油苯，气味、颜色，均与石油苯一致。

The redox separation conditions were investigated in detail. It was indicated that TBAPI exhibited appropriate oxidation intensity and well selectivity, thiolethers can be oxidized into sulphoxide, but it cannot oxidize thiols.

详细考察了氧化还原分离条件，实验结果表明，TBAPI具有适宜的氧化强度和良好的选择性，它能将硫醚硫氧化成亚砜，且在同条件下，对噻吩硫不起作用。

The derivatives of the amino acids containing sulphur synthesizedfrom three sulphydry amino acids such as methione, cysteine and cystine play an important role on the methylation,sulphuration, detoxication and ,antioxidation and are very useful in pharmaceutic and food industry.

含硫氨基酸衍生物主要由三个常见的含硫氨基酸——蛋氨酸，半胱氨酸，胱氨酸衍生转化而来，可以在体内参与转甲基，转硫基等生化过程，同时也具有抗氧化，清除自由基等功能，在医药和食品中具有重要的应用价值。

Ion nitriding+ion sulphurization duplex treatment can extend significantly the endurance life of sulphide layer, and improve very obviously the anti-scuffing behavior of surface at any speed.

喷丸处理在表面形成的大量缺陷促进了渗硫过程中硫向基体内部的扩渗，从而增加了渗硫层的厚度。

Based on the research results, the shot peening+ion sulphurization and ion nitriding+ion sulphurization duplex treatments were used to treat the steel surfaces, the effect of sulphide layer could be further developed.

依据研究结果，对钢铁表面进行喷丸+离子渗硫、离子渗氮+离子渗硫复合处理，以进一步发挥渗硫层的作用。

So the difficult sequence of cracking to remove the sulfur for different sulfur compounds is that thiophene, benzothiophene＞alkyl side-chains of thiophenic compounds＞mercaptan, sulfur ether.

总之，不同含硫化合物裂化脱硫的难度顺序为：噻吩、苯并噻吩＞烷基噻吩＞硫醇、硫醚。
