ABSTRACT:
Novel 3-sulfinatomethyl or 3-sulfonatomethyl-4-sulfomethyl-pyrrolidinium betaines are disclosed which have the formula ##STR1## These novel compounds are obtained by reacting diallyl-triallyl ammonium salts or their methallyl derivatives with hydrogen sulfite in the presence of peroxo disulfates alone or in a mixture with other oxidation agents with a pH-value-range from 1.5 to 6.0 in a watery solution, whereby in light of the selection of the amount of hydrogen sulfite in combination with the amount peroxo disulfate different SO.sub.2.sup.- --or SO.sub.3 .sup.- substituted sulfomethyl-pyrralidinium betaines are generated.
The novel compounds are effective as specific tensides in a wide pH-range and can be extensively used as intermediary products.
