Abstract
EQUIPO PARA PONER EN PRACTICA UN PROCEDIMIENTO PARA LA PRODUCCION CONTINUA DE UNA HIDROXIALQUILCELULOSA SOLUBLE EN AGUA O DE UN ESTER MIXTO SOLUBLE EN AGUA A BASE DE UNA HIDROXIALQUICELULOSA. CONSISTENTE EN UN APARATO QUE OPERA A PRESION ATMOSFERICA Y PROVISTO DE AGITADOR, EN EL QUE SE REALIZA LA ALCALINIZACION DE LA CELULOSA, A PARTIR DE LA SUSPENSION INTRODUCIDA EN EL MISMO. A CONTINUACION SE DISPONE POR LO MENOS UN APARATO PROVISTO DE AGUTADOR EN EL QUE SE VERIFICA LA ETERIFICACION PARCIAL Y/O SI ES NECESARIO, LA MODIFICACION DE LA CELULOSA, EFECTUANDOSE LA ETERIFICACION A UNOS 40C, BAJO PRESION MANOMETRICA DE HASTA UNAS 3 BATERIAS Y CON UN TIEMPO DE PERMANENCIA DE UNOS QUINCE A NOVENTA MINUTOS, HASTA ALCANZAR UN GRADO DE SUSTITUCION DE 0,5 A 1,5, APROXIMADANTE. DESPUES DE SER HOMOGENIZADA LA SUSPENSION MEDIANTE UN DISPOSITIVO ADECUADO, SE INTRODUCE EN UN REACTOR TUBULAR, EN EL QUE SE AJUSTA SU TEMPERATURA MEDIANTE UNA CAMISA Y SE COMPLETA LA ETERIFICACION. EL TIEMPO DE PERMANENCIA EN ELREACTOR TUBULAR ES DE SETENTA A CIENTO OCHENTA MINUTOS, A UNA TEMPERATURA DE 30C A 120C Y BAJO PRESION MONOMETRICA DE HASTA 10 BARIAS APROXIMADAMENTE. FINALMENTE LA PRESION, PROCEDENTE DEL ULTIMO TUBO DEL REACTOR, SE TRANSFIERE A UN DISPOSITIVO REFRIGERANTE, Y A CONTINUACION SE APLICA EL TRATAMIENTO FINAL SEGUN PROCEDIMIENTOS CONOCIDOS.
