Abstract

En un proceso para esterificar ácido (met)acrílico con alcanol en presencia de un catalizador de esterificacion en el que los compuestos de partida no reaccionados y el éster (met)acrílico se separan mediante destilacion y un producto inferior que contiene ésteres oxi se obtiene, el producto inferior se separa y el producto inferior se mezcla directamente con ácido (met)acrílico oligomérico y los ésteres oxi presentes en el producto inferior se disocian a una temperatura elevada en presencia de catalizadores ácidos diferentes del ácido (met)acrílico oligomérico o bien, los ésteres oxi se separan primero mediante destilacion el producto inferior, el destilado se mezcla con ácido (met)acrílico oligomérico y se disocia a una temperatura elevada en presencia de catalizadores ácidos diferentes alácido (met)acrílico oligomérico.
