摘　　要：为了解决农用乳化剂对石油依存度大、环境友好性差等问题,以可再生资源松香为原料,经异构化及Diels-Alder加成反应合成了马来松香,然后与聚乙二醇600反应,合成马来松香聚乙二醇酯表面活性剂(SM600);用傅里叶红外光谱仪(FT-IR)和凝胶色谱仪(GPC)对产物的结构进行表征,并对其外观颜色、酸值、水溶液的pH值、粘度、浊点、聚合度(DP)进行检测,以及对表面张力(γ)、临界胶束质量分数(w_(CMC))、泡沫性能(FP)、乳化性能(EP)和亲水亲油平衡值(HLB)等表面活性性能进行研究。结果表明:SM600在室温下呈棕红色液体单相透明,具有酸值低、粘度低及浊点高等特点,其水溶液呈中性,聚合度为1.81,表面张力和临界胶束质量分数分别为36.139 mN·m^(-1)和0.063%,表现出良好的泡沫性能、乳化性能和亲水性。原料天然可再生,合成工艺简单,产品性能良好,可用于替代烷基酚聚氧乙烯醚乳化剂。In order to solve the problems of high dependence on petroleum and poor environmental friendliness of agricultural emulsifiers,rosin,a renewable resource,was utilized as the raw material to synthesize maleic rosin through isomerization and Diels-Alder addition reactions.Subsequently,maleic rosin was reacted with polyethylene glycol 600 to synthesize a malay rosin polyethylene glycol ester surfactant(SM600).The structural characterization of the product was performed using Fourier-transform infrared spectroscopy(FT-IR)and gel permeation chromatography(GPC).Additionally,the appearance color,acid value,pH value of the aqueous solution,viscosity,cloud point and degree of polymerization(DP)were measured.Furthermore,surface tension(γ),critical micelle mass fraction(w_(CMC)),foam performance(FP),emulsification performance(EP),and hydrophilic-lipophilic balance(HLB)were studied to evaluate the surface activity performance.The results indicate that SM600 appears as a reddish-brown liquid at room temperature,exhibiting characteristics such as low acid value,low viscosity and high cloud point.Its aqueous solution is neutral with a polymerization degree of 1.81.The surface tension and critical micelle mass fraction are 36.139 mN·m^(-1)and 0.063%,respectively,demonstrating excellent foam performance,emulsification performance and hydrophilicity.The raw materials are naturally renewable,the synthesis process is simple,and the product exhibits excellent performance,making it a potential substitute for alkylphenol polyoxyethylene ether emulsifiers.
