Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE VAPORIZACION DE UNA SOLUCION DE HIDRATO DE HIDRACINA QUE CONSISTE EN CALENTAR ESTA SOLUCION EN FASE LIQUIDA Y A CONTINUACION EN EXPANDIRLA PARA PROVOCAR LA VAPORIZACION. SE HA DESCUBIERTO QUE ESTE PROCEDIMIENTO PERMITE EVITAR LA DESCOMPOSICION DEL HIDRATO DE HIDRACINA.LA INVENCION ES PARTICULARMENTE UTIL PARA EL HERVIDOR DE UNA COLUMNA EN LA QUE SE EFECTUA LA HIDROLISIS DE UNA AZINA R 1 R 2 C=N.N=CR 1 R 2 (EN LA QUE R 1 Y R 2 SON ALQUILOS QUE TIENEN HASTA 12 ATOMOS DE CARBONO) CON RECUPERACION DE HIDRATO DE HIDRACINA EN EL PIE Y DE CETONA R 1 R 2 C=0 EN LA CABEZA.
