摘要
采用碱熔融法由4—氯代邻苯二甲酸酐制备4—羟基邻苯二甲酸酐,测定了产物的理化性质,并考察了反应物、温度、时间、添加剂及碱用量等条件对产物收率和纯度的影响。
4-Hydroxyphthalic anhydride was prepared from 4-chlorophthalic anhyolride by an alkali-melt process and characterized by melting point measurement,colourating reaction,elemental analysis,IR and 1H NMR,The influences of reaction condition on the purity and yield of product were also discussed.
