Abstract

Process for the manufacture of pentaerythritol, in which sodium hydroxide is added to an aqueous solution containing pentaerythritol and sodium formate, in order to crystallize sodium formate for the separation thereof and the formate liberated solution is circulated for use as part of the initial reaction solution, characterized in that at least a part of the reaction solution containing pentaerythritol formals is thermally treated within a ph range of 4.5 to 5.5 at a temperature of 120 to 170º c. For 20 to 120 minutes, the pentaerythritol that has formed is separated and crystallized, sodium hydroxide is added to the separate solution containing pentaerythritol and sodium formate, in order to crystallize the sodium formate, and the crystallized sodium formate is removed.
