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. .

Sorbent sheet from polymer fibers and sorbent particles

Sorbent sheet from polymer fibers and sorbent particles. Kolpin, Barbara E.; Brownlee, David C. (Minnesota Mining and Mfg. Co. , USA). Eur. Pat. Appl. EP 88533 A2 14 Sep 1983, 19 pp. DESIGNATED STATES: R: CH, DE, FR, GB, IT, LI, SE. (English). (European Patent Organization). CODEN: EPXXDW. CLASS: IC: D04H001-56; A61L015-00. APPLICATION: EP 83-300776 16 Feb 1983. PRIORITY: US 82-354806 4 Mar 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) A sorbent sheet product comprises a web of blown fibers and an array of solid high-sorbency liq.-sorbent polymer particles carried in the web. The blown fibers are prepd. by extruding liq. fiber-forming material into a high-velocity gaseous stream where the extruded material is attenuated and drawn into fibers. Thus, 2 sets of sheets were prepd. from 5 mm polypropylene microfibers, sorbent particles comprising Permasorb 29 [89468-84-8] and surfactant particles of Aerosol OT-B [577-11-7]. The sorbent and surfactant particles were mixed together and introduced into a stream of microfibers using an app. in which the die orifices of the 2 dies were sepd. from one another by 6 in.In this experiment, several chemicals are used like 9005-25-8 and 89468-84-8 The polymer was extruded through the orifices and air heated to 370° was forced through them. The resulting sheets were immersed in water and the sorbency was measured. .
