摘　　要：以对硝基苯甲酸(PNBA)、十二醇(LAC)、十四醇、十六醇和十八醇为原料,用浓硫酸催化,直接合成了系列新型增塑剂对硝基苯甲酸长碳链醇酯。通过熔点、红外光谱及核磁共振(1H NMR)等方法对产物的结构进行了表征。并以对硝基苯甲酸十二醇酯合成为例,通过正交试验确定了最佳反应条件:n(PNBA)∶n(LAC)=1∶2,反应时间t为8 h,催化剂用量为1%,产率达95.35%。A new series of plasticizers higher alkyl 4-nitrobenzoates were synthesized with 4-nitrobenzoic acid, dodecyl alcohol, tetradecyl alcohol, hexadecyl alcohol and stearyl alcohol as raw materials.The structures of target compounds were characterized by means of melting point, infrared spectrum and ~H-NMR spectra.Through the orthogonal experiment of the 4-nitrobenzoic acid dodecyl ester, the optimal preparation condition was n （ PNBA ） ： n （ LAC ） =1：2, the reaction time t was 8 h, the amount of catalyst was 1%, the production rate was 95.35%.
