Preparation and Characterization of Rubber Seed Oil Based Polyol
摘要
Abstract
Rubber seed oil based polyol was prepared by using epoxidized rubber seed oil(ERSO) as raw materials,methanol and isopropanol as ring-opening reagents,and fluoboric acid as catalyst,the preparation conditions were investigated with the hydroxyl value of product as index,and the characterization of product was also studied.The results showed that the optimum reaction conditions were reaction time 30min,reaction temperature 70℃,the mass ratio of to alcohol to ERSO 4∶1,the amount of fluoboric acid 1%(based on the mass of ERSO),the mass ratio of isopropanol to methanol 1∶1.The results of verification experiment showed that the acid value,hydroxyl value,average molecular weight,moisture content and viscosity of rubber seed oil based polyol prepared under the optimum reaction conditions were 2.68mg/g,219.32mg/g,870.21,0.08% and 4791mPa·s,respectively.Furthermore,the chemical structure of rubber seed oil based polyol was characterized by FT-IR,1H NMR and 13C NMR,the results showed that the polyol was formed by the ring-opening reaction of epoxy group of ERSO.关键词
