【摘要】：目前高品质含硫化学品在国内仍有较大市场,部分甚至供不应求;回收废气中的硫化氢并深加工,既经济又环保。本文梳理了无机硫化物、硫醇、硫醚、硫酚、硫代酰胺、含硫杂环、有机二硫化物、高价硫有机物在内的8大类共计16种含硫化合物,介绍了它们的理化性质、主要用途以及市场供应情况;详细阐述了国内外主要合成方法的研究进展,着重分析了工业路线以及以硫化氢为原料的合成路线,比较有代表性的诸如生产硫化钠和硫氢化钠的吸收法,生产硫化锌的均匀沉淀法,生产甲硫醇的甲醇-硫化氢法,生产乙硫醇的氯乙烷法和乙烯-硫化氢法,生产2-巯基乙醇的环氧乙烷-硫化氢法,生产巯基乙酸的氯乙酸-硫氢化钠法和氯乙酸-硫化氢法,生产叔十二碳硫醇的十二烯-硫化氢加成法,生产二甲硫醚的二硫化碳-甲醇法和硫化氢-甲醇法,生产蛋氨酸的氰醇法和海因法,生产聚苯硫醚的Phillips法、硫磺法和硫化氢法,合成苯硫酚的硫化氢-氯苯法,生产硫脲的硫化氢-氰氨化钙法和硫化氢-氰胺法,生产四氢噻吩的噻吩加氢法和四氢呋喃-硫化氢法,生产二甲基二硫的硫酸二甲酯法和甲醇硫化法,以及通过二氧化氮氧化二甲硫醚的方法生产二甲亚砜。合理开发硫化氢废气的下游产品,需要从市场定位、技术手段、资源整合等多方面综合考虑;从当前的市场现状分析,蛋氨酸、聚苯硫醚等均具有广阔的市场发展前景,是今后研究工作的重要方向。
[Abstract]:At present, there is still a large market in China for high quality sulfur containing chemicals, some of which are in short supply. It is economical and environmentally friendly to recover hydrogen sulfide from waste gas and further process it. This paper reviews inorganic sulfides, mercaptan, thiol, thiophenols, thioamides, thioamides. There are 16 kinds of sulfur compounds in 8 categories, including heterocyclic sulfur, organic disulfide and high sulfur organic compounds. Their physical and chemical properties, main uses and market supply are introduced. The research progress of the main synthetic methods at home and abroad is described in detail. The industrial route and the synthesis route using hydrogen sulfide as the raw material are emphatically analyzed, and the typical absorption methods such as the production of sodium sulfide and sodium sulphide are compared. Homogeneous precipitation for the production of zinc sulfide, methanol-hydrogen sulfide for the production of methyl mercaptan, chloroethane and ethylene-hydrogen sulfide for the production of ethanethiol, and ethylene oxide hydrogen sulfide for the production of 2-mercaptoethanol, The chloroacetic acid-sodium sulfide and chloroacetic acid-hydrogen sulfide processes, the 12 ene-hydrogen sulfide addition process for the production of tert-#number0# carbon-mercaptan, the carbon-methanol disulphide process and the hydrogen sulphide methanol process for the production of dimethyl sulfide, Cyanide and hydantoin processes for the production of methionine, Phillips for the production of polyphenylene sulfide, sulfur and hydrogen sulfide, hydrogen sulfide and chlorobenzene for the synthesis of phenylthiophenol, and calcium sulphide cyanide and hydrogen sulfide cyanamide for the production of thiourea, Thiophene hydrogenation and tetrahydrofuran-hydrogen sulfide production of tetrahydrothiophene, dimethyl sulfate and methanol vulcanization of dimethyl disulfide, And the production of dimethyl sulfoxide by nitrogen dioxide oxidation of dimethyl sulfoxide. The reasonable development of downstream products of hydrogen sulfide waste gas requires comprehensive consideration from many aspects, such as market positioning, technical means, resource integration, etc. Methionine, polyphenylene sulfide and so on have broad market prospects and are the important research direction in the future.
