Liquid surfactants containing sulfosuccinates

Liquid surfactants containing sulfosuccinates. Peterka, Vlastimil; Haumer, Jaroslav; Kepl, Jiri; Vodak, Zdenek; Nikl, Stanislav; Vacha, Jaroslav (Czech. ). Czech. 1639-66-3 and 57-50-1 are also occured in this study. CS 204939 B 1 Jul 1983,7 pp. (Czech). (Czechoslovakia). CODEN: CZXXA9. CLASS: IC: C11D001-04. APPLICATION: CS 79-8686 13 Aug 1979. DOCUMENT TYPE: Patent CA Section: 46 (Surface Active Agents and Detergents) Title products, useful as laundry agents, are prepd. from crude sulfonation products of dialkyl maleates and additives which bind free NH3 and remove turbidity. Thus, crude gel after sulfonation of di(2-ethylhexyl) maleate with aq. NaHSO4 contained di(2-ethylhexyl) Na sulfosuccinate [577-11-7] 58, 2-ethylhexanol [104-76-7] 1, NH3 1.5, water 39, and nonidentified by-products 2 parts. Treating the mixt. with 4 parts sorbitol [50-70-4] and 2 parts 40% aq. HCHO [50-00-0] gave a clear soln. having cloud point 0°, viscosity 180 mPa-s, and good wetting and washing properties. .
