Abstract

In this study, nano-emulsions were prepared by phase inversion temperature within the system liquid paraffin /Span80-Tween80/–water and also the effect of NaCl concentrations on phase inversion temperature (PIT) system and droplet sizes of liquid paraffin were studied. The changes in electrical conductivity with temperature for emulsions with 10 wt % liquid paraffin, 12 wt % surfactant mixture of Span80 and Tween80 and 0.01 to 0.5 M NaCl aqueous solution were measured by conductivity meter, and middle temperature within the range of extra reduction in conductivity as PIT in each case was considered. The results show that, with increasing concentration of NaCl from 0.01 to 0.5 M, PIT decreased logarithmically from 62 to 53°C, and also the mean droplet size of paraffin increased from 21.1 to 30.3 nm respectively. Nano-emulsions also are transparent.

NaCl浓度对液体石蜡纳米乳液的相转化温度和液滴尺寸的影响

摘要

在这项研究中，通过在液体石蜡/ Span80-Tween80 /-水系统中的相转化温度制备纳米乳液，并研究了NaCl浓度对相转化温度（PIT）系统和液体石蜡液滴大小的影响。用电导率仪测量含10 wt％液体石蜡，12 wt％Span80和Tween80的表面活性剂混合物以及0.01至0.5 M NaCl水溶液的乳液的电导率随温度的变化，中间温度在电导率额外降低的范围内因为在每种情况下都考虑了PIT。结果表明，随着NaCl浓度从0.01 M增加到0.5 M，PIT从62到53°C呈对数减少，石蜡的平均液滴尺寸也从21.1 nm增加到30.3 nm。纳米乳液也是透明的。
