Dimethoxymethane Production process introduction

The neopentyl glycol product synthesis method at home and abroad is divided into two kinds, sodium formate method and hydrogenation method. At present, most of the neopentyl glycol units in our country use sodium formate method.

Sodium formate process principle
 Isobutyraldehyde and formaldehyde at 30-35 ° C, pH value of 9-11, the presence of an alkali catalyst condensation to produce hydroxyl tert-butyraldehyde, With excess formaldehyde in the alkali conditions reduced to neopentyl glycol, Formaldehyde is oxidized and reacts with alkali to form sodium formate. The reaction solution was neutralized with formic acid and distillation dehydration under reduced pressure. The concentrated solution was subjected to a layered extraction and  remove the sodium formate. After cooling, crystallization and separation, the neopentyl glycol product was obtained.
