Abstract: There are disclosed a method and apparatus for effecting a chemical reaction. There is provided an aspirator-mixer or zone to which the reaction mass is pumped to activate the same and into which another reactant is furnished and from which admixed reaction mass and reactant are discharged into a reaction zone in which the concentration or proportion of a vaporous or gaseous reactant is maintained at a level as desired by sucking therefrom into the suction side of the aspirator-mixer or zone any excess of such reactant. In one embodiment, a mercaptan is oxidized to corresponding disulfides with oxygen and the oxygen level in the reaction zone is maintained as desired by sucking off into the suction side of the aspirator-mixer any oxygen in the reaction zone in excess of that desired therein.

Abstract: In preparing organic sulfides by reacting olefins (e.g., butylenes) with a sulfur halide to form a sulfohalogenated intermediate which is subsequently sulfurized and dehalogenated by reaction with an aqueous solution of an alkali metal sulfide compound to form a noncorrosive organic sulfide product of high sulfur content, the copper strip corrosion activity is improved by resulfurizing the sulfurized olefin by contacting it with additional aqueous metal sulfide in the presence of a lower molecular weight alcohol, such as isopropanol.

Abstract: High molecular weight polysulfide polymers are produced by a novel process using polythiodiglycol, polymerizing it with an acid catalyst and with means for removing the water of reaction to make a medium molecular weight halogen-terminated polymer. The resultant halogen-terminated polymer may then be reacted with sodium polysulfide to form a latex dispersion of very high molecular weight. The dispersion may then be converted to --SH terminated polymers by the usual methods.
