在 2 5℃条件下 ,测定了不同浓度的羟丙基壳聚糖 (HPCHS)溶液 /表面活性剂 (聚氧乙烯(2 3)醚月桂醇 (BRIJ35)、十六烷基三甲基溴化铵 (CTAB)、十二烷基硫酸钠 (SDS)、二甲基十二烷基甜菜碱 (C1 2 BE) ) /正丁醇 (n- C4H9OH) /正辛烷 (n- C8H1 8)体系微乳液拟三元相图。结果表明 ,在所研究的浓度范围内 ,羟丙基壳聚糖对不同类型表面活性剂体系微乳液的形成有不同的影响 :(1 )除C1 2 BE体系外羟丙基壳聚糖的加入均在一定程度上改善了原有体系微乳区的形成和稳定 ;(2 )羟丙基壳聚糖溶液在 1 0 ,1 0和 5g/ L浓度时分别使 BRIJ35,CTAB和 SDS体系微乳区面积达到最大 ;(3)羟丙基壳聚糖的加入没有明显改变 C1 2 BE体系的微乳区面积。 Different concentrations of hydroxypropylchitosan (HPCHS) solution / surfactant (polyoxyethylene (2 3) ether lauryl alcohol (BRIJ 35), cetyltrimethylphosphonium bromide (CTAB), sodium dodecyl sulfate (SDS), dimethyl dodecyl betaine (C1 2 BE) / n-butanol (n-C4H9OH) / n-octane Microemulsion pseudo-ternary phase diagram. The results showed that hydroxypropyl chitosan had different effects on the microemulsion formation of different surfactant systems in the concentration range studied: (1) Addition of hydroxypropyl chitosan except C1 2 BE (2) When the hydroxypropyl chitosan solution at the concentrations of 10, 10 and 5 g / L, the microemulsion of BRIJ35, CTAB and SDS were respectively microencapsulated (3) The addition of hydroxypropyl chitosan did not significantly change the microemulsion area of ​​C1 2 BE system.
