| 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. |
| Keywords: | low concentration formic acid purification boron oxide |
