Abstract

L'invention se rapporte à un procédé qui sert à produire des hydrochlorométhanes, par exemple du chloroforme, avec des niveaux de sélectivité élevés et selon des rendements élevés en réduisant des polychlorométhanes, par exemple du tétrachlorure de carbone, enprésence d'un catalyseur de réduction. Il est essentiel de procéder à la réduction dans la phase liquide pour empêcher efficacement la formation concomittante d'impuretés, par exemple polymères, qui désactivent le catalyseur. Ce faisant le catalyseur peut développer pleinement ses niveaux de sélectivité et d'activité élevés. Comme catalyseur, on choisit de façon appropriée au moins un élément parmi les éléments des groupes 8, 9 et 10 du tableau périodique, tel que le ruthénium, le rhodium, le palladium ou le platine. On peut également utiliser de façon appropriée un catalyseur à base de n'importe lequel des éléments mentionnés ci-dessus et contenant en outre au moins l'un des éléments du groupe 11, par exemple le cuivre, l'argent ou l'or. Au moment où il faut procéder en continu à la réduction en phase liquide, il est préférable d'utiliser un lit fixe et plus particulièrement un lit stillatoire. Ce procédé est également très valable comme procédé pour convertir du tétrachlorure de carbone, dont l'utilisation est régulée par la loi pour la sauvegarde de l'environnement, par exemple en chloroforme, lequel est utile comme matériau de départ de divers composés au fluor.
