Study on Preparation and Properties the of Water in-gasoline Microemulsion

探讨了汽油微乳体系中 ,不同乳化方式、表面活性剂的配比、助表面活性剂对掺水量和稳定性的影响 ;并对制得的微乳汽油进行性能测试。研究结果表明 :当助表面活性剂与阳离子表面活性剂的质量比为 2时 ,制得的微乳汽油中掺水量最适宜燃烧 ;阴阳离子表面活性剂质量比为 9∶1复配作乳化剂时 ,不用助表面活性剂也易制得稳定的微乳汽油 ;上述微乳汽油的电导率、粘度符合燃油标准 ;稳定性在 10～4 0℃ ,可存在一年以上。该微乳汽油具有节能、环保作用。

The influence of different emulsion process,mixture ratio of surface active agent and cosurfactant to the watering quantity and stability in the petrol microemulsion system was discussed.The performance of the maked petrol microemulsion was tested.The result indicates that,when the mass ratio of the cosurfactant to the cationic surface active agent is 2∶1,the watering quantity of the petrol microemulsion is most suitable to combustion;when the mass ratio of the anionic surface active agent to the cationic surface active agent in the retum-service emolsifier is 9∶1,the stable petrol microemulsion is easy to achieve even without cosurfactant.The electric conductivity and viscosity of the petrol microemulsion meet the necessity of fuel oil standard.Its stability can hold over one year at 10～40℃.This petrol microemulsion has the function of energy conservation and environmental protection.
