Patent number: 4410709Abstract: The invention relates to new sulfobetaines and a process for the manufacture of cyclic sulfobetaines of a substituted 4-sulfomethyl-pyrrolidinium betaine type.Diallylammonium combinations are converted with salts of sulfurous acid, under good mixing and mild reaction conditions, in the presence of catalytic acting transition metallic ions of the first, fifth, seventh or eighth secondary groups of the Period Table and initiators at pH 2-9. The process is technologically easily carried out, requires only little energy, while the combinations according to this invention can be selectively manufactured with a nearly quantitative yield. The fact that no carcinogenic alkylates are employed, technical chemicals and tap water may be used, and hardly any by-products are formed, may be regarded as further advantages of this process.The substances can be used for multiple purposes, for instance as conductive coating and antistatic materials.Type: GrantFiled: July 8, 1981Date of Patent: October 18, 1983Assignee: Akademie der Wissenschaften der DDRInventors: Roland Ohme, Detlef Ballschuh, Jochen Rusche, Horst Seibt, Kristina Geneis, Gunter Kretzschmar
