Title (EN) METHOD OF PRODUCING HYDROFLUOROCARBONS
(FR) PROCEDE DE PRODUCTION D'HYDROFLUOROCARBONES
Abstract: front page image
(EN)A process for producing fluorinated C1 HFCs comprising fluorinating a reactive organic compound, such as dichloromethane, to produce a reaction product comprising at least the desired C1 HFC, such as difluoromethane (HFC-32), unreacted reactive organic compound and a byproduct, such as chloromethane (HCC-40), having a boiling point between the boiling point of said desired hydrofluorocarbon compound and said reactive organic compound; and removing from the reaction product at least a substantial portion of the byproduct to produce a high purity product stream.
(FR)L'invention concerne un procédé de production de C1 HFC fluorés, consistant à fluorer un composé organique réactif, tel que dichlorométhane, afin de produire un produit de réaction comprenant au moins le C1 HFC voulu, tel que difluorométhane (HFC-32), un composé organique réactif n'ayant pas réagi et un sous-produit, tel que chlorométhane (HCC-40), possédant un point d'ébullition se situant entre le point d'ébullition du composé d'hydrofluorocarbone voulu et celui du composé organique réactif, et à éliminer du produit de réaction au moins une partie substantielle du sous-produit pour produire un flux de produit de grande pureté.
