摘要：以煤油、盐酸、表面活性剂和助表面活性剂为主要原料,考察了表面活性剂配比对煤油微乳酸稳定性的影响、不同表面活性剂用量下的最大增溶酸量、微乳液和微乳酸的拟三元相图、煤油微乳酸的粒径分布、耐盐能力及缓释效果。结果表明,采用CTAC与NP-15复配可获得稳定的煤油微乳酸体系;体系中表面活性剂的最佳用量为10.7%(w),氯化氢含量达到10.9%(w);当CTAC∶NP-15=3∶2,AS1∶AS2=1∶2,助表面活性剂∶表面活性剂=1∶1时,可以得到较大的微乳酸单相区。该微乳酸体系粒径小、分布均匀,具有良好的稳定性和耐温性,耐CaCl2能力可以达到60000mg/L。与相同浓度的盐酸水溶液相比,煤油微乳酸缓释反应效果显著。
The microemulsified acid system composed by kerosene, hydrochloric acid, surfactants and cosurfactants was investigated in this paper. The stability of microemulsified acid,the phase behavior of the microemulsified system and the maximal dissolution capacity of the acid under different surfactant concentration were studied. The granularity distributing,the salt tolerance ability and the controlled acid release were also observed. The results showed that the stable microemulsified acid system could be prepared using CTAC and NP-15. The appropriate weight of mixture surfactants was 10.7%, and the weight of HCl got to the maximum 10.9% in the microemulsified acid system. A big amount of microemulsified acid region appeared when CTAC/NP-15=3∶2,AS1/ AS2=1∶2,cosurfactants / surfactants=1∶1. The kerosene microemulsified acid system possessed small granularity and good stability under different temperatures. The tolerance of CaCl2 reached 60 000mg/L. Compared with the same concentration hydrochloric acid solution, the effect of controlled acid release in the kerosene microemulsified acid system was remarkable.
