Abstract
Process for recovering pentaerythritol and alkali formate from the mother liquor obtained in the production process of pentaerythritol characterized in that alkali formate is precipitated from the mother liquor by means of a suitable organic solvent, preferably methanol which is recovered by distillation after removing the the resulting aqueous solution is recycled for a successive pentaerythritol preparation operation in which the pentaerythritol contained in the recycled aqueous solution is extracted together with the pentaerythritol produced by the condensation of the formaldehyde and the acetaldehyde.
