| Abstract: | The preparation process of formic acid(FA) by the method of phosphorus acid in high-pressure reaction kettle was studied.At the same time,the influence of the ratio of phosphoric acid and sodium formate,temperature,reaction time,the addition of pyrophosphoric acid(PPi)on synthesize yield rate of formic acid ratio were observed and the best process conditions for synthesize formic acid.The result showed that the ultimately productive rate of formic acid reach 90%and concentration of formic acid reach 96% whe... |
