Sulfated ethers

The detergent range alcohols and their derivatives have a wide variety of uses ia consumer and iadustrial products either because of surface-active properties, or as a means of iatroduciag a long chain moiety iato a chemical compound. The major use is as surfactants (qv) ia detergents and cleaning products. Only a small amount of the alcohol is used as-is rather most is used as derivatives such as the poly(oxyethylene) ethers and the sulfated ethers, the alkyl sulfates, and the esters of other acids, eg, phosphoric acid and monocarboxyhc and dicarboxyhc acids. Major use areas are given ia Table 11. [Pg.449]

To 10 g of cyclohexane-1,4-oxide is added 40 ml of 12 N hydrochloric acid solution. The solution is mixed thoroughly and allowed to stand at room temperature for 8 days. Water (50 ml) is added to the mixture, the phases are separated, the aqueous phase is extracted with 25 ml of ether, and the ether extract is combined with the organic phase. The ether solution is washed with bicarbonate solution and water and dried over anhydrous sodium sulfate. Ether and unreacted oxide are removed on a rotary evaporator, and the product is recrystallized from petroleum ether, mp 82-83 (yield, 8 g). [Pg.52]

The major subgroups of anionic surfactants include the alkali carboxylates (soaps), sulfates, sulfonates, and to a smaller degree, phosphates. The esterification of alcohol with sulfuric acid yields probably the best-studied surfactant, sodium dodecylsulfate or SDS. SDS, a sulfate ester, is an extremely effective emulsifier because of its high-electrostatic repulsion. Other sulfates are, for example, sulfated esters from fatty acids, sulfated ethers, and sulfated fats and oils. Sulfonates stem from the reaction of sulfonic acid with suitable substrates. Members of the class of sulfonates are, for example, sulfonic acid salts or aliphatic sulfonates. Other anionic surfactants include substances such as carboxylated soaps and esters of phosphoric acid. [Pg.1829]

Temperature Stability The long-term thermal stability of injected surfactants in the reservoir environment is a must for an effective surfactant formulation. The thermal stability of several ionic and nonionic surfactants has been reported in terms of the time required for half of the surfactant to decompose (e.g. half-life).Most of the surfactants investigated decomposed by first-order kinetics. The interfacial activity of surfactant solutions after six months at 80°C was reported by Akstinat. The results showed that the stability of the surfactants was in the order ether sulfonates > ether carboximethylates > ether sulfates > ether phosphates. [Pg.217]
