Title
(EN) PROCESS FOR PRODUCING ORGANIC POLYSULFIDES
(FR) PROCEDE DE PRODUCTION DE POLYSULFIDES ORGANIQUES
Abstract
(EN)
A process for producing an organic polysulfide compound comprises contacting, in th presence of a catalyst, a mercaptan with elemental sulfur to produce a product medium and contacting the product medium with a material comprising carbon dioxide or a carbon dioxide-generating compound wherein the catalyst comprises a base and optionally a surfactant and the organic polysulfide contains about 3 or more sulfur atoms per molecule.
(FR)
L'invention porte sur un procédé de production d'un polysulfide organique, qui consiste à placer un mercaptan au contact d'un soufre élémentaire, en présence d'un catalyseur, en vue de produire un milieu de produits. Le milieu de produits est ensuite placé au contact d'une matière contenant du dioxyde de carbone ou un composé générateur de dioxyde de carbone. Le catalyseur comprend une base et, éventuellement, un tensioactif; et le polysulfide organique contient environ au moins 3 atomes de soufre par molécule.
