  • Patent number: 6852883
    Abstract: In the process according to the invention for the manufacture of an alkanesulphonyl chloride RCH2—SO2Cl by oxidative chlorolysis of the corresponding mercaptan RCH2—SH, the mercaptan and water are introduced into the reaction mixture in the form of a dispersion of water in the mercaptan. This makes it possible to obtain both an alkanesulphonyl chloride of very good quality and a hydrochloric acid of commercial grade.

  • Patent number: 6303814
    Abstract: N-(Triazoloazinyl)arylsulfonamide compounds, such as 2,6-dimethoxy-N-(8-chloro-5-methoxy[1,2,4]triazolo[1,5-c]pyrimidin-2-yl)benzenesulfonamide, 2-methoxy-4-(trifluoromethyl)-N-(5,8-dimethoxy[1,2,4]triazolo[1,5-c]pyrimidin-2-yl)pyridine-3-sulfonamide, and 2-methoxy-6-methoxycarbonyl-N-(5,8-dimethoxy[1,2,4]triazolo[1,5-a]pyridin-2-yl)benzenesulfonamide were prepared from appropriately substituted 2-amino[1,2,4]triazolo [1,5-c]pyrimidine and 2-amino[1,2,4]triazolo[1,5-a]pyridine compounds and appropriately substituted benzene sulfonyl chloride and pyridine-3-sulfonyl chloride compounds. The compounds were found to be useful as herbicides.

  • Patent number: 5220070
    Abstract: A process was developed to prepare 1,3-diamino-5-pentafluorosulfanylbenzene. This process involved two steps: preparing the dinitro compound, 1,3-dinitro-5-pentafluorosulfanylbenzene, and reducing this compound to form the corresponding diamine. This diamine was reacted with various dianhydrides, diacidchlorides, and epoxy resins to form polyimides, polyamides, and crosslinked epoxies. These polymers were used to prepare semi-permeable membranes, wire coatings, and films.
