本文系统地研究用不同浓度的NaOH,KOH和NH_4OH对D_2EHPA(1M)-仲辛醇(15％)-煤油萃取体系进行皂化过程中微乳状液的生成和相区变化:1.测定了有机相中微乳状液生成的条件;2.测定了皂化过程中有机相的电导、粘度和含水量,发现在等当点时有机相都生成微乳状液,而且电导、粘度和含水量也有最大值;3.研究了长链醇的存在与含量对生成微乳状液的影响.通过这些研究,有助于选择和确定这一体系的皂化与萃取条件.
In this paper, we systematically studied the formation and phase change of microemulsion in the saponification of D_2EHPA (1M) -soctanol (15%) - kerosene extraction system with different concentrations of NaOH, KOH and NH 4 OH: 1. The effects of organic phase Microemulsion generated conditions; 2 Determination of the organic phase conductivity, viscosity and moisture content of the saponification process and found that the organic phase at the equivalent point of the formation of micro-emulsion, and the conductance, viscosity and water content also has the maximum; The effects of the presence and amount of long-chain alcohols on the formation of microemulsions were investigated, and these studies will help to select and determine the saponification and extraction conditions of this system.
