Abstract

PROCEDIMIENTO PARA LA PREPARACION CONTINUA DE DIMETILVINILCARBINOL (DMVC) MEDIANTE REACCION CONTINUA DE PRENOL CON LA SOLUCION ACUOSA DE UN ACIDO PROTONICO EN EL RESIDUO, O EN LA PARTE INFERIOR DE UNA COLUMNA DE RECTIFICACION DEL DMVC FORMADO, EN FORMA DE UNA MEZCLA AZEOTROPICA CON AGUA, QUE SE CARACTERIZA PORQUE A) DURANTE LA REACCION SE PROCURA, QUE NO SE FORME EN LA MEZCLA NINGUNA MEZCLA LIQUIDA DE DOS FASES, B) EL DMVC FORMADO SE DESTILA EN UNA RELACION DE RECICLAMIENTO DE AL MENOS 2, SIN QUE HAYA DESTILADO DE LA COLUMNA PRACTICAMENTE NINGUN PRENOL, Y C) EL VOLUMEN DE LA REACCION Y/O LA CANTIDAD QUE SE AÑADE DE PRENOL POR HORA Y/O LA CONCENTRACION EN PROTONES EN LA MEZCLA SE MIDE DE TAL MANERA, QUE EL COCIENTE DE FLUIDO COMO INDICE DE CONCENTRACION DE PERMANENCIA, PROCEDENTE DEL VOLUMEN DE LA REACCION Y DEL VOLUMEN AÑADIDO DE PRENOL POR HORA, SE MULTIPLICA POR LA CONCENTRACION EN PROTONES DE LA MEZCLA UN VALOR ENTRE 0,001 H . MOL/L, Y 1 H . MOL/L. AQUI SE EVITA LA FORMACION DE UNA MEZCLA LIQUIDA DE DOS FASES EN LA MEZCLA REACTIVA ADEMAS DE QUE SE EVITA UN GRAN EXCESO DE PRENOL, PORQUE DE LA MEZCLA REACTIVA SE TOMA DE MANERA CONTINUA UNA CORRIENTE PARCIAL, QUE SE LLEVA A TRAVES DE UN RECIPIENTE SEPARADOR DE FASES, AHI SE RETIRA LAS CANTIDADES MINIMAS FORMADAS EN EL TRANSCURSO DE LA REACCION EN PRODUCTOS SECUNDARIOS ORGANICOS QUE SON PARCIALMENTE SOLUBLES EN AGUA O NO SON HIDROSOLUBLES, Y LA FASE ACUOSA SE RECICLA OTRA VEZ AL VOLUMEN DE LA REACCION.
