以二甲基二烯丙基氯化铵(DMDAAC)、丙烯酰胺(AM)和顺丁烯二酸(MA)为乳化单体,正丁醇为助乳化剂,聚氧乙烯辛基苯酚醚-10(Triton X-10)、失水山梨醇油酸酯(Span 80)和聚氧乙烯山梨醇酐硬脂酸酯(Tween 60)为乳化剂,液体石蜡、异辛烷和环己烷为有机溶剂,进行体系增溶实验。采用电导法和染料法研究了单体总质量浓度、AM摩尔分数、阴阳离子单体配比、乳化剂质量分数、助乳化剂与复合乳化剂质量比等对微乳液体系最小乳化剂用量(Smin)和最大增溶水量的影响。结果表明,异辛烷与Span80/Tween60复合乳化剂组成的乳化体系增溶性较好;当单体总质量浓度为40%、n(AM)∶n(MA)∶n(DMDAAC)=6∶2∶2、亲水亲油平衡值(HLB值)为11.30、w(复合乳化剂)=33%和m(助乳化剂)∶m(复合乳化剂)=1∶7时,所形成的反相微乳液增溶水量大、乳化剂用量少且稳定性强。
Diallyl ammonium chloride (DMDAAC), acrylamide (AM) and maleic acid (MA) as emulsifier, n-butanol as co-emulsifier, polyoxyethylene octylphenol ether-10 (Triton X-10), sorbitan oleate (Span 80) and polyoxyethylene sorbitan stearate (Tween 60) as emulsifiers, liquid paraffin, isooctane and cyclohexane as organic solvents , The system solubilization experiments. The minimum amount of emulsifier (Smin), the amount of emulsifier (Mmin), the amount of emulsifier and the mass ratio of emulsifier to emulsifier were studied by conductivity method and dye method. ) And the maximum amount of solubilized water. The results showed that the solubilization of emulsified system composed of isooctane and Span80 / Tween60 emulsifier was better. When the monomer concentration was 40%, the ratio of n (AM): n (MA): n (DMDAAC) = 6: 2 : 2, an HLB value of 11.30, w (composite emulsifier) = 33% and m (co-emulsifier): m Microemulsion solubilized water, emulsifier dosage and stability.
