摘　　要：针对所研究的甜菜碱乳状液运用了宏观脱水率和微观显微镜观察的方法,并通过粘度计测定了乳状液的粘度,对A(烷基二甲基磺丙基甜菜碱)和B(烷基二甲基羟丙基磺基甜菜碱)两个系列甜菜碱的乳化性能进行了研究。结果表明,AB两个系列甜菜碱的乳化性能都随长烷基链碳原子数的增加先逐渐增强,当A系列长烷基链碳原子数达到14,B系列长烷基链碳原子数达到16,乳化性最好,继续增加长烷基链碳原子数,乳化性能减弱。AB两个系列的甜菜碱都随着浓度的增加乳化性能逐渐增强。随着甜菜碱长烷基链碳原子数的增加。The macro-dehydration rate and the microscopic observation method were applied to study betaine emulsion, and the viscosity of the emulsion was measured by a viscometer. The emulsifying properties of two series betaine of A（alkyl dimethyl sulfopropyl betaine） and B（alkyl dimethyl hydroxypropyl sulfobetaine） were studied. The results showed that, when carbon atoms of the long alkyl chain increased, the emulsifying properties of the two series of betaine were improved. When the number of carbon atoms of the long alkyl chain of the series A reached 14, the number of carbon atoms of the long alkyl chain of the series B reached 16, their emulsifying properties were the best, and then with increasing of the carbon number of the long alkyl chain, emulsifying properties weakened. When the concentration of two series of betaine increased, the emulsifying properties were improved. With increasing of carbon atoms of the long alkyl chain, the emulsifying property of series B was better than that of series A.
