Abstract
Procedimiento perfeccionado para la obtención de anhídridos alifáticos, inferiores particularmente al ácido y el anhídrido acético, por oxidación del aldehido correspondiente en un baño de reacción constituido esencialmente por una mezcla de acido y de anhídrido que contiene un catalizador, con arrastre de los productos de la reacción por medio de la corriente de gases oxigenados, caracterizándose por el hecho de que se someta la mezcla de gas y de vapores que salen del baño de reacción a una condensación parcial en un desflemador con caudal de agua regulable y se devuelve al baño la cantidad de líquido necesaria para mantener en él un nivel constante.
