Synthesis and performance of polymeric surfactants based on epoxidized soybean oil grafted hydroxyethyl cellulose
摘要
Abstract
Epoxidized soybean oil grafted hydroxyethyl cellulose (ESO - HEC)was synthesized through the grafting reaction between epoxidized soybean oil (ESO)and hydroxyethyl cellulose (HEC)with stannic chloride (SnCl 4 )as catalyst in dimethyl sulfoxide (DMSO)as process agent. After hydrolysis in the presence of sodium hydroxide,and the hydrolyzed product was treated with hydrochloric acid,the ESO - HEC converted into an acidic product H - ESO - HEC. Then three kinds of polymeric surfactant,H - ESO - HEC - Na,were obtained through neutralizing the carboxyl groups of H - ESO - HEC. Chemical structure of H - ESO - HEC was characterized by Fourier transform infrared spectroscopy (FT - IR). Thermogravimetric (TG)analysis demonstrated that the thermo - stability of H - ESO - HEC was noticeably higher than that of HEC. The dynamic surface tension of the surfactant decreases as the mass concentration of surfactant increases. Furthermore,when the mass concentration of the surfactant reaches its critical micelle concentration value,the minimum surface tension could reach to 29 mN/ m. The results showed that the foaming power and foam stability of the surfactants increases with the increase of ESO that was grafted on HEC. The H - ESO - HEC - Na surfactants prepared under different conditions may reduce heptane / water interfacial tension to a similar value around 9. 8 mN/ m.关键词
