Experimental Study on Preparation and Stability of Methanol —Diesel Microemulsion
The methanol diescl micro-emulsion was prepared by mixing surfactants oleic acid,diethanolamine,span80,OP-4 in the methanol-diesel hybrid system.And by orthogonal experiment method and viscosity index ,the impact of preparation temperature,stirring time,stirring speed,cosurfactant dosage and methanol content on stability of the methanol diesel micro-emulsion were investigated.The experimental results show that when m(oleic acid)/m (diethanolamine)/ m (span80)/m(OP-4) = 10:2:3:2,content of dissolved methanol increases to the maximum ,viscosity index of the sample is minimum ,viscosity change is minimum at the constant temperature 50 ℃,which presents the best stability of methanol diesel micro-emulsion formula,the order of impact factors is as follows: methanol content > preparation temperature> stirring time> cosurfactant dosage> stirring speed.Methanol diesel microemulsions with best stability can be prepared under the experimental conditions of temperature 30 ℃,stirring time 12min,stirring speed 300 r/min,methanol 5.0 % (wt).
