Cryo-distillation de produits organiques. Cette technique permet de distiller sans chauffer, en travaillant sous vide et en utilisant de l’azote liquide pour permettre la purification des produits organiques. Le solvant de polymérisation est ici séché sur un mélange sodium benzophénone (liquide violet dans le ballon à gauche) puis récupéré après cryo-distillation dans une burette graduée.
