Abstract

PROCEDIMIENTO DE PRODUCCION DE OXIMAS ANHIDRAS QUE RESULTA SENCILLA POR LA SEPARACION DE LA OXIMA DE UNA SOLUCION ACUOSA. EL PROCEDIMIENTO ES VENTAJOSO PORQUE SE ELIMINAN LOS POTENCIALES RIESGOS DE EXPLOSION DE LOS PROCEDIMIENTOS ACTUALES Y SE PARA LA OXIMA FACILMENTE DE LA FASE ACUOSA. EL PROCEDIMIENTO COMPRENDE LAS ETAPAS DE (A) VAPORIZAR UNA SOLUCION ACUOSA DE OXIMA; (B) VAPORIZAR UN DISOLVENTE ORGANICO HIDROINMISCIBLE DE LA OXIMA EN QUE EL PUNTO DE EBULLICION DEL DISOLVENTE ES INFERIOR AL PUNTO DE EBULLICION DE LA OXIMA; (C) COMBINAR LOS VAPORES; (D) CONDENSAR LOS VAPORES RECOGIDOS; (E) SEPARAR LA FASE ORGANICA DEL CONDENSADO DE LA FASE ACUOSA; Y (F) RECUPERAR LA OXIMA ANHIDRA DE LA FASE ORGANICA RETIRADA. LAS OXIMAS ANHIDRAS PRODUCIDAS POR EL PRESENTE PROCEDIMIENTO SON UTILES EN APLICACIONES TALES COMO CONDENSACION DE ISOCIANATOS Y LA FORMACION DE CARBONATOS.
