摘　　要：以苯酚、丙酮为原料,以自制的多金属氧酸盐[(CH_2)_5NH_2]_5BW_(12)O_(40)为催化剂,催化制备双酚A,对双酚A进行熔点测定和红外光谱(IR)分析。探索了酚酮摩尔比、催化剂用量、反应时间等因素对双酚A收率的影响。实验结果表明:溶剂甲苯45 m L,丙酮6 m L(0.08 mol),最佳反应温度45℃,最佳反应时间2.5 h,n(丙酮):n(苯酚):n(催化剂)=1:4:0.03,产物收率达到75%以上。Bisphenol A was synthesized from phenol and acetone using Keggin compound[（CH2）5NH2]5BW（12）O（40） as catalyst. And its melting point was determined, and IR analysis was carried out. The effect of main reaction conditions on the yield of bisphenol A was investigated. The optimum conditions were obtained as follows： n（phenol）∶n（acetone）∶n（catalyst）= 4∶1∶0.03, toluene 45 ml,reaction temperature 45 ℃,reaction time 2 h.Under above conditions,the product yield is above 75%.
