(FR) PROCÉDÉ DE COPRODUCTION DE 1-CHLORO -3,3,3-TRIFLUOROPROPÈNE, DE 2,3,3,3-TÉTRAFLUOROPROPÈNE ET DE 1,3,3,3-TÉTRAFLUOROPROPÈNE
(ZH) 一种联产1-氯-3,3,3-三氟丙烯、2,3,3,3-四氟丙烯和1,3,3,3-四氟丙烯的方法
Abstract:
(EN) Disclosed is a method for the coproduction of 1-chloro-3,3,3-trifluoropropene, 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene. A gas mixture of hydrogen fluoride and 1,1,1,3,3-pentachloropropane and 1,1,2,3-tetrachloropropene are simultaneously fed into a first reactor and reacted to obtain a reaction product; the obtained product is directly fed into a second reactor and reacted under the action of a catalyst, and hydrogen chloride is separated from the obtained product; and 1-chloro-3,3,3-trifluoropropene, 2,3,3,3-tetrafluoropropene and 1,3,3,3-tetrafluoropropene products are respectively obtained after washing with water, washing with an alkali, drying and then rectifying. The present invention has the advantages of flexible production, a simple process, small investment, low energy consumption and a high conversion rate.
(FR) L'invention concerne un procédé de coproduction de 1-chloro -3,3,3-trifluoropropène, de 2,3,3,3-tétrafluoropropène et de 1,3,3,3-tétrafluoropropène. Un mélange gazeux de fluorure d'hydrogène et de 1,1,1,3,3-pentachloropropane et de 1,1,2,3-tétrachloropropène sont simultanément introduits dans un premier réacteur et mis à réagir pour obtenir un produit de réaction; le produit obtenu est directement introduit dans un second réacteur et mis à réagir sous l'action d'un catalyseur, et du chlorure d'hydrogène est séparé du produit obtenu; et du 1-chloro -3,3,3-trifluoropropène, le 2,3,3,3-tétrafluoropropène et les produits de 1,3,3,3-tétrafluoropropène sont respectivement obtenus après lavage à l'eau, lavage avec un alcali, séchage puis rectification. La présente invention présente les avantages d'une production flexible, d'un procédé simple, d'un faible investissement, d'une faible consommation d'énergie et d'un taux de conversion élevé.
(ZH) 本发明公开了一种联产1-氯-3,3,3-三氟丙烯、2,3,3,3-四氟丙烯和1,3,3,3-四氟丙烯的方法,将氟化氢和1,1,1,3,3-五氯丙烷混合气与1,1,2,3-四氯丙烯同时通入第一反应器进行反应,得到反应产物;将得到的产物直接进入第二反应器,在催化剂的作用下进行反应,将得到的产物分离氯化氢、水洗、碱洗、干燥后精馏分别得到1-氯-3,3,3-三氟丙烯、2,3,3,3-四氟丙烯和1,3,3,3-四氟丙烯产品。本发明具有生产灵活、工艺简单、投资小、能耗低,转化率高的优点。
