Abstract

Alkali metal acrylates are produced by reacting acrolein in an aqueous solution containing an alkali metal base and having a pH in excess of 10.5 at a temperature below 20 DEG C., preferably between -5 DEG and +15 DEG C., with free oxygen in the presence of a silver catalyst. Suitable bases are hydroxides or carbonates of sodium and potassium. The acrolein is added as an aqueous solution or by charging the oxidizing gas with vaporized acrolein. The process may be batchwise or continuous and part of the catalyst may be replaced by fresh catalyst and the spent catalyst reactivated. The products may be polymerized to polyacrylates. The free acid is obtained in high purity by acidification, preferably after filtering of the catalyst, followed by extraction with esters, ketones or hydrocarbons. The acid is esterified with an alcohol in the presence of an acid catalyst, preferably in a continuous column at the top of which high purity ester and excess alcohol are withdrawn. Examples are given of continuous and repeated batch processes using silver oxide as catalyst and comparative runs using temperatures above 20 DEG C. and using sodium bicarbonates as the alkaline medium.
