Abstract

La presente invencion se refiere a un procedimiento para separar trioxano de una mezcla líquida que contiene trioxano, agua y formaldehído, caracterizado porque la mezcla líquida se destila en una primera etapa de destilacion a baja presion, el destilado resultante se destila en una segunda eta de destilacion a una presion mayor y el trioxano se recoge como producto de cola.
