Abstract

LA PRESENTE INVENCION SE REFIERE A UN PROCESO MEJORADO DE PREPARACION DE CITRAL EN FASE LIQUIDA A PARTIR DE PRENOL Y DE PRENAL EN EL QUE, EN UN MISMO RECINTO DE REACCION, SE CONDENSA EL PRENAL Y EL PRENOL EN PRESENCIA DE UN ACIDO MINERAL CON UNA CONCENTRACION DE APROXIMADAMENTE 5.10 ELEVADO A -3 MOLES POR UN MOL DE PRENAL, SE NEUTRALIZA 90 A 95% DEL ACIDO INTRODUCIDO Y TRAS LA ELIMINACION DEL PRENAL Y DEL PRENOL EXCEDENTARIO, SE DISTILA EL CITRAL.
