Abstract
Procedimiento para la obtención de ésteres a partir de ácidos carboxílicos insaturados con un punto de ebullición más elevado que agua, en especial ácido acrílico o metacrílico, y alcoholes polivalentes en un reactor (2), conteniendo la mezcla de reacción líquida (1) inhibidores de polimerización, y separándose al menos parcialmente el agua de reacción producida en estado de vapor, caracterizado porque se elimina una parte de la fase de gas/vapor de la mezcla de reacción (1) del reactor (2), se condensa parcialmente la misma en un desflemador (6), se alimenta a la mezcla de gas/vapor ascendente, así como al condensado saliente un líquido que contiene el inhibidor de polimerización desde la cabeza del desflemador (6), y se devuelve de nuevo al reactor (2) la mezcla saliente total.
