PROCEDIMIENTO CONTINUO PARA LA PREPARACION DE SOLUCIONES A- CUOSAS CONCENTRADAS DE HIDRATO DE HIDRAZINA.

摘要

A continuous method for the preparation of concentrated aqueous solutions of hydrazine hydrate from ketazines which are slightly soluble in water, by hydrolysis and distillation under pressure using a distillation column. The column is fed with the ketazine or ketazines and water wherein the water/azine molar ratio ranges between 5 and 7.75.
