摘要:
采用磷酸与甲酸钠为原料,并加入五氧化二磷作脱水剂,在高压釜内反应,制取甲酸并联产磷酸钠盐.对原料配比、五氧化二磷加入量、蒸馏温度对甲酸产品浓度、产率的影响进行了实验.实验结果表明:在一定实验体系中,甲酸钠与磷酸摩尔比为1∶1.03、五氧化二磷加入量为35.73 g、蒸馏温度为115℃时,甲酸最终浓度可达到95.75 %.
Abstract:
Formic acid and mixture of phosphate was synthesized by phosphoric acid and sodium formate in highpressure reaction kettle with phosphorus pentoxide as dehydrating agent.This article discussed the influence factors of productivity of formic acid such as the mol ratio of sodium formate and phosphoric acid,the addition of phosphorus pentoxide, vapouring temperature.The results showed that the ultimately productive rate of formic acid reached 95.75% when the mol ratio of sodium formate and phosphoric acid was 1∶1.03,the quantity of phosphorus pentoxide was 35.73 g, vapouring temperature was 115℃.
