  • Patent number: 6248687
    Abstract: Presulfurizing process and presulfurization promoter for a desulfurization catalyst to be used in a hydrodesulfurization unit of petroleum refinery of high molecular hydrocarbons, in which fresh metal oxide in said desulfurization catalyst is sulfurized with hydrogen sulfide produced from sulfur-containing compounds in a feed stream. In the invention, a compound having mercapto alkylthio group: HS—CmH2m—S— (in which “m” is an integer of 2 to 4) is added as promoter at a proportion of 10 ppm to 0.5% by weight and presulfurization is promoted at 180 to 260° C.

  • Patent number: 6207838
    Abstract: Electrolysis of organic disulfides in liquid sulfur dioxide is used to obtain organothiating agents, which can then be reacted with appropriate substrates to effect the synthesis of organothioaromatic compounds efficiently and in high yields. With appropriate phenolic compounds, regioselective substitution occurs in which para substitution greatly exceeds ortho substitution.

  • Patent number: 6198003
    Abstract: A highly efficient method of producing alkyl mercaptan and/or dialkyl monosulfides which involves employing carbon dioxide as an internal coolant is described. Only negligible amounts of carbonyl sulfide were formed. In addition, relatively easy separation of carbon dioxide from the reaction mixture facilitates an efficient coolant recycle process, giving a simple and effective mode of temperature control.

  • Patent number: 6121496
    Abstract: The present invention relates to a process for the acylation of an aromatic thioether. In its preferred variant, the invention resides in a process for the condensation of acetic anhydride or acetyl chloride with thioanisole. The process for the acylation of an aromatic thioether according to the invention is characterised in that it consists in reacting said thioether with an acylating agent chosen from the group formed by the halides of carboxylic acids and the anhydrides of carboxylic acids, in the presence of an effective quantity of an acid zeolite.
