| Abstract: | An oil-soluble viscosity reducer is designed and synthesized with monomers including poly-alcohol,acrylic acid and maleic anhydride.The effect of synthesis conditions on the viscosity-reducing result of the product is discussed,and the effects of the dosage of viscosity reducer agent and temperature on its viscosity-reducing result are investigated,then the optimal reaction conditions are obtained:the substance mass ratio of poly-alcohol to acrylic acid to maleic anhydride is 1.0 ∶ 0.4 ∶ 1.0,reaction temperature is 115~120 ℃,reaction time is 4.5~5 h,it has the best viscosity-reducing result,whose viscosity reducing rate reached 86.90%,when its concentration in viscous crude oil is 750 mg/L at 50 ℃. |
