Abstract
PROCEDIMIENTO PARA LA OBTENCION DE CLORURO DE ACIDO GAMMA-CLOROACETOACETICO A PARTIR DE CLORO Y DICETENA. SE INTRODUCEN DE MODO CONTINUO EN ISOCORRIENTE EN UN REACTOR TUBULAR UNA DISOLUCION DE CLORO Y OTRA DE DICETENA EN EL MISMO DISOLVENTE INERTE, UN HIDROCARBURO CLORADO, EN UNA PROPORCION MOLAR DE CLORO A DICETENA DE 0,9:1 A 0,9:1,2, MEZCLANDOSE AMBAS DISOLUCIONES INMEDIATAMENTE Y PRODUCIENDOSE UNA CIRCULACION TURBULENTA. TANTO LA DISOLUCION DE CLORO COMO DE DICETENA SON DEL 1 AL 15 POR 100. EL TUBO DE REACCION SE ENFRIA DESDE EL EXTERIOR MEDIANTE SALMUERA, DE MODO QUE SE CONSIGA UNA TEMPERATURA DE REACCION INFERIOR AL PUNTO DE EBULLICION DEL DISOLVENTE. EL PRODUCTO DE REACCION SE SEPARA POR DESTILACION.
