Zusammenfassung:The invention discloses a sodium ethoxide production process, which belongs to the technical field of sodium ethoxide production, and specifically comprises the following steps: S1, preparing an ethanol alkali solution in which sodium hydroxide is dissolved with absolute ethyl alcohol, recovering the heat of the product through a raw material preheater E1, and introducing the ethanol alkali solution to the top of a reactive distillation tower T1; and S2, the ethanol alkali solution is in reverse contact with absolute ethyl alcohol steam introduced from the bottom of the rectifying tower, sodium ethoxide and water are generated through reaction, and the qualified product sodium ethoxide is sent out from the bottom of the tower. The invention relates to a technology for preparing sodium ethoxide through reaction of absolute ethyl alcohol (or 95% ethyl alcohol) and sodium hydroxide (caustic soda flakes), a high-purity sodium ethoxide solution can be prepared by utilizing a reactive distillation tower, hydrous et
