甲酸浓缩提纯新方法及应用研究
Application study on new approach of concentration and purification of Formic Acid
【摘要】 文章介绍了低浓度甲酸浓缩提纯方法———硼矸提纯法,克服了甲酸与水共沸而产生的分离难题,提纯后的甲酸浓度达93%以上,可替代试剂甲酸应用于分析检测,在节能降耗、降低测试成本和环境保护方面都具有实际意义。
【Abstract】 This paper introduces a new approach of concentration and purification of formic acid at low concentrations-boron oxide purification,which avoids the problem of separation introduced by the azeotrope of formic acid and water.After purification,the formic acid concentration is over 93% and can be used as a substitute for reagent grade formic acid used in analysis and detection.The result shows that it has practical significance in energy saving and consumption reducing,decreasing the test cost and environmental protection.
