95% high concentration formic acid production method
2006
The invention discloses a manufacturing method of high-density formic acid, which is characterized by the following: adopting low-oxidation phosphoric acid with strong reducing property and pentavalent phosphor polymer pattern phosphoric acid as acidifying agent to acidify sodium formate; reducing the decomposition of formic acid greatly; reducing the generation of water; improving the density of formic acid obviously.
