The invention discloses a method for continuously synthesizing 1, 1-diethoxypropane. The invention mixes absolute ethyl alcohol and propionaldehyde in a mixer, then pumps the mixture into a preheater, after preheating, continuously reacts in a trickle bed of an immobilized catalyst, and after neutralization and rectification of reaction liquid, 1-diethoxypropane with the purity of more than 98% is obtained. The invention can realize continuous industrial production, does not produce waste salt such as calcium chloride and the like, and realizes green synthesis. |
