Description

Hydrolysis device applied to sodium methoxide wastewater Technical Field The utility model relates to the technical field of sodium methoxide wastewater recovery equipment, in particular to a hydrolysis device applied to sodium methoxide wastewater. Background Sodium methoxide is mainly used in pharmaceutical industry, and is used as condensing agent, chemical reagent, catalyst for edible oil treatment, etc. in organic synthesis. The sodium methoxide product has two forms, namely solid and liquid, wherein the solid is sodium methoxide pure product, the liquid is sodium methoxide methanol solution, and the sodium methoxide content is 27.5% -31%. Sodium methoxide by an alkaline method is prepared by taking sodium hydroxide and methanol as raw materials, reacting in a synthesis tower to generate sodium methoxide product and water, removing water generated by the reaction by using the synthesis tower, obtaining sodium methoxide methanol solution product with the content of 30% at the bottom of the tower, rectifying methanol gas and water vapor at the top of the tower by entering a methanol recovery tower, obtaining anhydrous methanol at the top of the methanol recovery tower, and discharging process wastewater at the bottom of the methanol recovery tower.
