At 80℃,95℃,112℃,when using 2,2-dichloroethyl ether,1,3-dibromropropane,1,4-dichlorobutane and ethyl cyanoacetate as bases,choosing toluene as solvent and DTMAB as catalyst,the apparent rate constant for systhesizing these products was obtained.
实验以DTMAB为催化剂,甲苯为溶剂,算出了在80℃,95℃,112℃时二氯乙醚,1,3—二溴丙烷,1,4—二氯丁烷与氰乙酸乙酯反应的表观速率常数。
