Abstract

Procédé perfectionné pour préparer des monohalogénocétones par réaction d'une cétone avec un halogène vaporisation On vaporise la cétone dans un récipient de vaporisation surmonté d'un tube, récipient de vaporisation dont la partie supérieure constitue un condenseur et la partie inférieure une colonne, la partie médiane contenant la chambre de réaction, on condense les vapeurs dans le condenseur de manière que le condensat goutte sur un dispositif pénétrant dans la chambre de réaction et réagisse à cet endroit avec l'halogène injecté au travers dudit dispositif, avec formation d'un produit de réaction qui est entraîné dans le récipient de vaporisation par le condensat gouttant du condenseur au travers d'un tube engagé dans la colonne. Le procédé selon l'invention donne les monohalogénocétones avec des rendements élevés et dans de hauts états de pureté.
