Abstract
Un proceso para preparar ácido acrílico y/o ésteres comprende los pasos de: (a) oxidacion de fase de gas catalítica de propeno y/o acroleina de ácido acrílico a fin de obtener un producto de reaccion gaseoso que comprende ácido acrílico, (b) absorcion con solvente del producto de reaccion, (c) destilacion del solvente cargado con el ácido acrílico para obtener un ácido acrílico crudo y el solvente, (d) purificacion del ácido acrílico crudo mediante cristalizacion, y (e) opcionalmente esterificacion del ácido acrílico cristalino.
