The invention provides a process for the preparation of 1234yf comprising (a) contacting 1,1, 2,3,3, 3-hexafluoropropene (1216) with hydrogen in the presence of a hydrogenation catalyst to produce 1,1,2,3,3,3-hexafluoropropane (236ea); (b) dehydrofluorinating 236ea to produce 1,2,3,3,3-pentafluoropropene (1225ye); (c) contacting 1225ye with hydrogen in the presence of a hydrogenation catalyst to produce 1,2,3,3,3-pentafluoropropane (245eb); and (d) dehydrofluorinating (245eb) to produce (1234yf).
该发明提供了一种制备1234yf的方法,包括(a)在氢化催化剂的存在下将1,1,2,3,3,3-六氟丙烯(1216)与氢接触,以产生1,1,2,3,3,3-六氟丙烷(236ea);(b)脱氟化236ea以产生1,2,3,3,3-五氟丙烯(1225ye);(c)在氢化催化剂的存在下将1225ye与氢接触,以产生1,2,3,3,3-五氟丙烷(245eb);以及(d)脱氟化(245eb)以产生(1234yf)。
