  • Procedure for the production of polymeric sulfur
    Patent number: 6555087
    Abstract: A procedure for the production of polymeric sulfur with improved stability that comprises the stages of: (a) cooling in a vessel for rapid cooling the sulfur vapor from the vaporization of molten sulfur, by bringing it into direct contact with a refrigerating suspension composed of carbon disulphide, soluble sulfur and polymeric sulfur, to a temperature such that part of the sulfur vapor is transformed into a powder-like polymeric sulfur, insoluble in carbon disulphide. (b) extracting the resulting suspension from the cooling vessel; (c) recycling part of said suspension to the vessel for cooling; and (d) sending the rest of the suspension to a maturation stage to stabilize the polymeric sulfur.
