Title (EN) PROCESS FOR PRODUCING DIALLYL DISULFIDE
(FR) PROCÉDÉ DE FABRICATION DE BISULFURE DIALLYLE
Abstract: front page image
(EN)The invention provides a process for forming diallyl disulfide. The process comprises A) mixing together sulfur and at least one alkali metal sulfide in an initial aqueous medium in which at least about 90 volume percent of said aqueous medium is water, such that a disulfide source is formed in said initial aqueous medium thereby forming a disulfide source-conatining aqueous medium, and B) mixing together at least a portion of said disulfide source-containing aqueous medium and at lease one allyl halide selected from allyl cloride, allyl bromide, or a mixture of any two or all three of these, in the absence of any additional solvent other than water, at a temperature in the range of about 40˚C to about 60˚C, such that diallyl disulfide is formed.
(FR)L’invention porte sur un procédé de fabrication de bisulfure diallyle. Le procédé consiste A) à mélanger du soufre et au moins un sulfure de métal alcalin dans un milieu aqueux initial dans lequel au moins environ 90 pour cent en volume dudit milieu aqueux est de l’eau, de telle sorte qu’une source de bisulfure est formée dans ledit milieu aqueux initial formant ainsi un milieu aqueux contenant une source de bisulfure et B) à mélanger au moins une portion dudit milieu aqueux contenant une source de bisulfure et au moins un halogénure allyle sélectionné parmi le chlorure allyle, le bromure allyle ou bien un mélange de deux d’entre eux ou des trois, en l’absence de tout solvant supplémentaire autre que l’eau, à une température comprise entre environ 40°C et environ 60°C, de manière à former du bisulfure diallyle.
