| 摘要 |
<p>The invention relates to a method for producing anhydrous, or essentially anhydrous formic acid, comprising firstly generating hydrous formic acid, by hydrolysis of methyl formate, whereby the methyl formate has previously been depleted of the methanol contained therein. Said method is characterised in that, prior to the hydrolysis of the methyl formate, methanol-containing methyl formate is depleted of methanol in a distillation column, whereby said column is simultaneously used for other further separating functions in the working up of the formic acid.</p> |
