Abstract

Description d'un procédé de distillation des esters de glycidile, qui sont des produits d'une réaction entre un acide monocarboxylique saturé à chaîne droite ou ramifiée, ou un sel de cet acide, et un monoépoxyde halosubstitué; selon ce procédé, le produit de ladite réaction est soumis à l'action du vide et de la température dans un appareil de distillation à film mince et à passage court, par exemple, dans un évaporateur de film balayé. Le distillat est beaucoup moins coloré que le produit avant la distillation et possède une stabilité de couleur et une thermostabilité accrues.
