1555. ---------------. [INDUSTRIAL CHEMIST AND CHEMICAL MANUFACTURER.] Mersol and Hostapon – Manufacture of Sulfonated Detergents in Germany. Vol. 23, 1947, pp. 242-249; CIOS Rept. XXVI-2, PB 6, 684, and XXXII-107, PB 6,650; BIOS Final Rept. 805, PB 49,196.
The nature, manufacture, and uses of Mersol and Hostapon are given. Mersol is a mixture of sulfo-chlorinated paraffins in the C9-C15 range, made by the action of SO2 and Cl in the presence of ultraviolet light on a hydrogenated Fischer-Tropsch Kogasin distillate (Mepasin). The reaction is known as the Reed reaction. Hostapon is a mixture of alkyl sulfonic acids produced directly by the sulfo-oxidation of Mepasin, the reaction being promoted either by ultraviolet light or with acetic anhydride. The Fischer-Tropsch fraction used for starting material was the 220°-330° C. or the 230°-320° C. cut. Flowsheets, detailed descriptions of the processes, and the outputs from the plants are given.
