【摘要】 本文测定了四种两性表面活性剂（ＢＳ－１２，ＯＢ－２，ＬＡＢ，ＬＡＯ）的表面张力、临界胶束浓度（ｃｍｃ）、等电区、发泡能力、润湿性、乳化作用、Ｋｒａｆｔ点和增稠性能；探讨了化学结构对其性能的影响关系更多还原

【Abstract】 We have determined surface tension, cmc, isoelectric zone, foam property, wetting property, emulsification, Krafft point, thickening property and hard waterresisting property of the four kinds of amphoteric surfactants (BS 12, OB 2, LAB, LAO). The relationships between the structures and the properties of these surfactants are discussed.更多还原
