摘　　要：以自制活性炭负载Keggin型配合物[(CH2)5NH2]4SiMo12O40为催化剂,苯酚、丙酮为原料,催化合成双酚A。对产品进行了熔点测定、元素分析和红外光谱(IR)分析。考察了酚酮配比、催化剂用量、反应时间等因素对双酚A收率的影响。结果表明:丙酮6 mL(0.080 2 mol),n(苯酚)∶n(丙酮)=4∶1,催化剂质量分数为7%,甲苯50 mL,反应温度40℃,反应时间2 h,产品收率达到70%以上,且催化剂可以连续使用6次以上,催化活性无明显降低。Bisphenol A was synthesized from phenol and acetone using activated charcoal supported Keggin compound [（CH2）5NH2]4SiMo12O40 of homemade catalyst.And melting point,element analysis,IR have been measured.The effects of main reaction conditions on the yield of bisphenol A were examined.The optimum conditions were obtained as follows：acetone 6 mL（0.080 2 mol）,n（phenol）∶n（acetone）=4∶1,catalyst dosage 7%,toluene 50 mL,reaction temperature 40 ℃,reaction time 2 h,the yield of product was above 70%,and the catalyst was recycled six times without loss activity.
