摘　　要：利用马来酸酐和 1 2、1 6、1 8醇合成马来酸单酯 ,确定n(酐 )∶n(醇 ) =1 .1∶1 ,温度 95～ 1 0 0℃ ,时间 3h ,马来酸1 2、1 6、1 8单酯的吸收率都高于 96%。用马来酸 1 8单酯与丙烯酸制备润滑型丙烯酸鞣剂 (MⅡ -1 8) ,通过正交试验 ,探讨酯 /酸、温度、过氧化苯甲酰 (BPO)和低碳醇用量对合成的影响 ,得到最佳条件∶n (酯 )∶n(酸 ) =1∶1 ,温度 80℃ ,BPO和低碳醇用量是单体质量的 0 .5 %和 2 2 % ,照此配方合成MⅡ 1 6/ 1 2。通过凝胶渗透色谱测定MⅡ分子量 ,数均分子量不超过 1 0 83 .1。将其用于铬鞣革的复鞣加脂 ,材料吸收率和成革增厚率高 ,革柔软、粒面细致 ,富有油感、弹性 ,具有一定防水性。用于铬鞣中的试验表明 :有助于铬的吸收 ,不降低收缩温度 。Maleic anhydride, dodecanol, hexadecanol and octadecanol were used as raw materials in synthesis of mono-maleate. In the condition of molar ratio of anhydride to alcohol 1.1∶1, reaction temperature 95～100℃and reaction time 3h, yields of mono-maleates can reach 96%. Mono-stearyl maleate and acrylic acid were used as raw materials in synthesis of lubricating acrylic tanning agent. Suitable conditions for synthesis of copolymer of acrylic acid and mono-stearyl maleate(MⅡ 18)were obtained: molar ratio of maleate to acrylic acid 1∶1, reaction temperature 80℃,amount of BPO 0.5 percent the weight of monomer and amount of alcohol 22 percent the weight of monomer. And copolymers of acrylic acid and mono-lauryl/ceto maleate(MⅡ 12/MⅡ 16)were synthesized in term of the conditions. Gel permeation chromatography showed that number-average molecular weight of MⅡ products were under 1083.1. They were applied in retanning and fatliquoring of wet blue. The thickness, nappinese, water resistance and softness as well as elasticity of the finished leather were increased. Tanning agents were applied in chrome tannage. The results showed that absorption of chrome and softness of chrome-tanned leathers were not improved and shrinkage temperatures didn't decrease.
