ABSTRACT:
A method is disclosed for partially resolving the components of a pentaerythritol waste liquor which contains pentaerythritol, polypentaerythritols, organic syrups, water, and an alkali metal formate which comprises acidifying the waste liquor to convert the alkali metal formate to formic acid and an alkali metal salt, adding a lower aliphatic alcohol to the acidified waste liquor to react with the formic acid to form a formate ester and to precipitate the alkali metal salt, removing the formate ester by distillation, and removing the precipitated alkali metal salt.
