Reaction Conditions:
with quaternary ammonium salt anion exchange resin in lithium hydroxide monohydrate at 30; for 4 h;Inert atmosphere;Temperature;
Steps:
1-19 Specific Example 19:
Adding absolute ethanol and ethyl acrylate to a 2-liter four-necked flask and before Example 19A total of 1500 grams of the fraction of anhydrous ethanol: ethyl acrylate, controlled temperature of 30 degrees ± 2 degrees, added to the catalyst of Example 18, stirring, rotating at a speed of not more than 120 rpm, the catalyst suspension dispersion is uniform, after 4 hours of reaction, Stirring was stopped, the catalyst was filtered off, and the ethyl acrylate content in the filtrate was determined to be 0.5%.The filtrate is added to the column of the rectification column, heated, and slowly rectified between 74-165 degrees to remove the ethanol and ethyl acrylate and a small amount of the forward fraction of ethyl 3-ethoxypropionate.99% of the product was collected with a yield of 98%.The catalyst is regenerated by recycling to the ethyl acrylate reaction until the end point content is above 1%.
