Title (EN) PROCESS FOR PRODUCING 2,3,3,3-TETRAFLUOROPROPENE
(FR) PROCÉDÉ DE FABRICATION DE 2,3,3,3-TÉTRAFLUOROPROPÈNE
(JA) 2,3,3,3-テトラフルオロプロペンの製造方法
Abstract: front page image
(EN)Provided is a process by which 2,3,3,3-tetrafluoropropene can be produced at a high transformation rate and stably for a long time. The process for producing 2,3,3,3-tetrafluoropropene involves causing 1,1-dichloro-2,3,3,3-tetrafluoropropene and/or 1-chloro-2,3,3,3-tetrafluoropropene as (a) starting compound(s) to react with hydrogen in the presence of a precious-metal catalyst loaded on activated carbon having an ash content of 3% or less as measured in accordance with ASTM D2866.
(FR)L'invention a pour objectif de fournir un procédé permettant de fabriquer un 2,3,3,3-tétrafluoropropène selon un taux de conversion élevé et stable sur une longue période. Plus précisément, l'invention concerne un procédé de fabrication de 2,3,3,3-tétrafluoropropène au cours duquel un composé de départ d'un 1,1-dichloro-2,3,3,3-tétrafluoropropène et/ou d'un 1-chloro-2,3,3,3-tétrafluoropropène, et un hydrogène sont mis en réaction en présence d'un catalyseur de métal noble chargé dans un charbon actif dont la teneur en cendres mesurée conformément à ASTM D2866 est inférieure ou égale à 3%.
(JA) 長時間安定して高い変換率で2,3,3,3-テトラフルオロプロペンを製造できる方法の提供を目的とする。 ASTM D2866に準じて測定される灰分が3%以下の活性炭に担持した貴金属触媒の存在下、1,1-ジクロロ-2,3,3,3-テトラフルオロプロペンおよび1-クロロ-2,3,3,3-テトラフルオロプロペンの少なくとも一方の原料化合物と、水素とを反応させる2,3,3,3-テトラフルオロプロペンの製造方法。
