Abstract

Procedimiento para la producción de metacrilato de metilo a partir de metacroleína en una reacción de esterificación oxidativa continua con oxígeno y metanol, que se lleva a cabo en fase líquida a una presión de 2 a 100 bar con un catalizador heterogéneo, en cuyo caso se trata de nanopartículas que contienen oro soportadas con un tamaño de partícula menor que 20 nm, caracterizado por que la fase líquida se extrae continuamente del reactor, y el valor de pH tras la extracción se ajusta a un valor de pH entre 5 y 9 tras la extracción por medio de adición de disolución básica fuera del reactor, y por que la fase líquida extraída se devuelve al reactor con un valor de pH entre 5 y 9 en al menos un 50 %.
