新型胺解原油降凝剂PSMA的合成与性能评价
Synthesis and properties evaluation of new aminated crude oil pour point depressant PSMA
摘要
Abstract
The copolymer poly(PSMA‐a) composed of maleic anhydride and octadecyl methacrylate was synthesized with dispersion copolymerization method by using polyvinylpylrrolidone (PVP) as the dispersant and ethanol as the dispersion medium .Then the polymer was amidated by aminobenzene . The structure and thermal stability of the final polymer (PSMA) were characterized by Fourier trans‐form infrared spectroscopy (FTIR) and thermal weight loss (TGA) .In this thesis ,the crude oil from Daqing Oilfield station was taken as the experimental subject ,the property of pour point depression and viscosity reduction were measured by differential scanning calorimetry (DSC) ,oil solidifying point tester and viscosity tester .Then ,the best ratio of monomer ,reaction temperature ,reaction time and dosage of initiator was determined through the orthogonal test .The results of the experi‐ment indicated that the best pour point depression and viscosity reduction effect were achieved when the amount of the PPD taken in the experiment was 750 mg/L and the PVP dosage was 8% of total monomer mass .关键词
