摘要
本文研究了丙三醇/水混合溶剂中十六烷基三甲基氯化铵(CTAC)溶液的粘度性质,考察了水杨酸钠(NaSal)浓度、CTAC浓度以及丙三醇体积分数等因素对CTAC胶束溶液粘度的影响,并与乙二醇/水混合溶剂中胶束的粘度进行比较。结果表明:在丙三醇/水混合溶剂中,当CTAC浓度一定时,CTAC溶液的相对粘度随着NaSal浓度的增大而增大;当NaSal浓度一定时,CTAC溶液的相对粘度随着CTAC浓度的增大出现最大值;CTAC溶液的相对粘度随着丙三醇体积分数的增大而下降。这种变化趋势与乙二醇/水混合溶剂中的粘度性质相类似。
The viscosity of cetyltrimethyl ammonium chloride（CTAC） solution in glycerol/water mixtures was studied in this paper.The effects of concentration of sodium salicylate（NaSal） and CTAC,the volume fraction of glycerol on the viscosity of CTAC were investigated,and the results were compared with the viscosity of CTAC in ethylene glycol/water mixtures.It is shown that relative viscosity of CTAC solution increases with the increase of the concentration of NaSal when the concentration of CTAC is certain.Relative viscosity of CTAC solution appears maximum with the increase of the concentration of CTAC when the concentration of NaSal is certain.Relative viscosity of CTAC solution decreases with the increase of the volume fraction of glycerol.This trend is similar with the viscosity in ethylene glycol/water mixtures.
