摘　　要：以丙烯酸(AA)和双环戊二烯(DCPD)为主要原料,合成了丙烯酸双环戊二烯酯(DCPA)。采用单因素试验法探讨了催化剂含量、单体配比、反应温度和反应时间等对DCPA收率的影响,从中优选出合成DCPA的最佳工艺条件。结果表明:以磷钨酸为催化剂,并且当反应温度为70℃、反应时间为10 h、n(AA)∶n(DCPD)=1.2∶1和w(磷钨酸)=2.0%时,DCPA的收率(52.41%)相对最高。With acrylic acid（AA） and dicyclopentadiene（DCPD） as main raw materials,a dicyclopentadiene acrylate（DCPA） was synthesized.The influences of catalyst contents,monomer ratio,reaction temperature and reaction time on yield of DCPA were discussed and optimal process conditions of synthesizing DCPA were preferred by single-factor experiment method.The results showed that the yield（52.41%） of DCPA was reversely maximal when phosphotungstic acid was used as a catalyst,and reaction temperature and reaction time were 70 ℃ and 10 h respectively,molar ratio of n（AA）∶n（DCPD） was 1.2∶1,and mass fraction of phosphotungstic acid was 2.0%.
