摘要
<正>纤维素基表面活性剂是一类具有亲水亲油基团的高分子化合物,它具有降低表面(界面)张力、润湿、乳化、发泡、洗涤等一系列性能。以羟乙基纤维素与环氧大豆油为原料,通过高速剪切将两者在水溶液中乳化,在SnCl_4催化条件下于室温发生反应,反应时间为20min。反应液通过乙酸乙酯洗涤,经纯化后得到
Cellulose-based surfactant is a kind of polymeric compound with both hydrophilic and lipophilic groups,which has the properties of lowering surface(interfacial) tension,wetting,emulsifying,foaming and washing.Epoxidized soybean oil(ESO) and hydroxyethyl cellulose(HEC) were used as raw materials and were homogeneous mixing through a homogenizer.SnCl_4 was added into the mixture as a catalyst.The reaction temperature and reaction time were 25℃ and 20 min,respectively.ESO modified HEC surfactants(ESO-HEC) were obtained through purification.The chemical structure and properties of ESO-HEC were characterized by FT-IR,NMR and TG.The properties of ESO-HEC-stabilized oil-in-water emulsions were studied.ESO-HEC-stabilized oil-in-water emulsions were prepared by blending 50%w/w soybean oil and 50%w/w ESO-HEC aqueous solution(0.01、0.1、0.5、0.8 and 1 g/L) together using a rotor-stator at 15000 rpm for 3 min.The emulsion stability,size determination,rheology behavior,surfactant behavior were investigated through ESO-HEC-stabilized oil-in-water emulsions under the condition of different ESO-HEC concentrations.
