Abstract
PROCEDIMIENTO PARA PREPARAR ETERES CICLICOS SUSTITUIDOS CON NITRATOALQUILO. CONSISTE EN (A) MEZCLAR SIMULTANEAMENTE UNA CORRIENTE DE NSI2OSI6 Y UNA CORRIENTE DE UN ETER CICLICO SUSTITUIDO CON HIDROXIALQUILO, CADA UNO DISUELTO EN UN DISOLVENTE ORGANICO INERTE, Y (B) SEPARAR RAPIDAMENTE LOS COPRODUCTOS DE ACIDO NITRICO Y NITRATOALQUILO ANTES DE QUE PUEDAN REACCIONAR ENTRE SI, PARA ROMPER EL ANILLO DE ETER. LA ETAPA (B) SE REALIZA CONVENIENTEMENTE ENFRIANDO BRUSCAMENTE LA CORRIENTE DE PRODUCTO, EN EL ESPACIO DE APROXIMADAMENTE 15 SEGUNDOS DESDE SU FORMACION, EN UNA SOLUCION ACUOSA DE CARACTER BASICO EN LA QUE EL ACIDO NITRICO SE TRANSFIERE DESDE LA FASE ORGANICA Y SE NEUTRALIZA. EL INVENTO ES UTIL PARA OBTENER OXIRANOS Y OXETANOS SUSTITUIDOS CON NITRATOALQUILO.
