摘　　要：以油酸甲酯与马来酸酐(MA)为原料制备了油酸甲酯基琥珀酸酐(ASA)、油酸甲酯基琥珀酸(MSA)、油酸甲酯基琥珀酸单甲酯(MMS)和油酸甲酯基琥珀酸双甲酯(MDS)作为防锈剂,采用气相色谱-质谱联用、电喷雾电离质谱、傅里叶红外光谱、核磁共振氢谱等手段分析确定了4种防锈剂的结构,并考察4种防锈剂在加氢柴油和150SN润滑油基础油中的防锈蚀性能。结果表明:在加氢柴油中,MSA添加质量分数25μg/g时防锈效果能达到无锈级别,MMS添加质量分数50μg/g时的防锈效果能达到无锈级别;在润滑油中,MSA添加质量分数50μg/g时防锈效果能达到无锈级别,MMS添加质量分数50μg/g时防锈效果能达到无锈级别。并且MSA酸值比工业防锈剂T746低100 mgKOH/g, MMS酸值比工业防锈剂T747低50 mgKOH/g,适用于调制酸值要求低的汽轮机油和液压油。Using methyl oleate and maleic anhydride(MA)as raw materials,methyl oleate succinic anhydride(ASA),methyl oleate succinic acid(MSA),methyl oleate monomethyl succinate(MMS)and methyl oleate dimethyl succinate(MDS)were prepared as anti-rust additive.The structures of four anti-rust additive were analyzed and determined by gas chromatography-mass spectrometry,electrospray ionization mass spectrometry,Fourier transform infrared spectrum and nuclear magnetic resonance spectroscopy,and the antirust properties of four anti-rust additives in hydrogenated diesel and 150SN lubricating base oil were investigated.The results show that when the mass fraction of MSA and MMS added in hydrogenated diesel is 25 and 50μg/g,respectively,the antirust effect can reach the rust-free level.When the mass fraction of MSA and MMS added in lubricating oil is 50μg/g,respectively,the anti-rust effect can reach the rust-free level.Besides,the MSA acid value is 100 mgKOH/g lower than the industrial anti-rust additive T746,and MMS acid value is 50 mgKOH/g lower than the industrial anti-rust additive T747,which is suitable for modulating steam turbine oil and hydraulic oil with low acid values.
