Abstract
SE FABRICA UN ESTER DE ACIDO ACRILICO POR REACCION DE DICHO ACIDO Y POR UN ALCOHOL ENTRE LOS MONOALCOHOLES PRIMARIOS Y SECUNDARIOS ALIFATICOS EN C{SUB,5} O POR ENCIMA, EN PRESENCIA DE UN ACIDO COMO CATALIZADOR DE ESTERIFICACION Y DE UN INHIBIDOR DE POLIMERIZACION, SIENDO EL ALCOHOL CAPAZ DE FORMAR UN HETEROAZEOTROPO CON AGUA, SIENDO EL AGUA FORMADA POR LA REACCION DE ESTERIFICACION ARRASTRADA POR DESTILACION EN UNA COLUMNA EN FORMA DE UNA MEZCLA HETEROAZEOTROPICA CON EL ALCOHOL, COMPRENDIENDO DICHA MEZCLA UNA CANTIDAD DE ACIDO ACRILICO QUE NO HA REACCIONADO, SE SOMETE A CONTINUACION, TRAS LA CONDENSACION, A UNA SEPARACION PARA DAR UNA FASE ORGANICA SUPERIOR QUE SE RECICLA EN CABEZA DE LA COLUMNA DE DESTILACION Y UNA FASE ACUOSA INFERIOR QUE SE TRASIEGA; SEGUN LA INVENCION SE CONDUCE UNA EXTRACCION (POR EJEMPLO EN UNA COLUMNA DE EXTRACCION CE) DE ACIDO ACRILICO CONTENIDO EN LA MEZCLA HETEROAZEOTROPICA CONDENSADA (M) DIRIGIDO A LA SEPARACION DE FASES POR UNA MEZCLA RICA EN ALCOHOL ESTERIFICANTE, Y SE REENVIA EN CABEZA DE LA COLUMNA DE DESTILACION (CD), EL ACIDO ACRILICO ASI EXTRAIDO, COMO CONSTITUYENTE DE LA FASE ORGANICA RECICLADA, CON AUMENTO DE LA TASA DE REFLUJO EN LA COLUMNA DE DESTILACION (CD) RESPECTO DEL REFLUJO NATURAL.
