Title:

METHOD FOR PRODUCING 2, 3, 3,3-TETRAFLUOROPROPENE

Document Type and Number:

WIPO Patent Application WO/2016/051900

Kind Code:

A1

Abstract:

Provided is a method with which a recycling process is established using substantially one reaction step, and 2,3,3,3-tetrafluoropropene (HFO-1234yf) can be efficiently produced. In the present invention, a method for producing 2, 3, 3, 3-tetrafluoropropene (HFO-1234yf) includes a step for reacting a fluorinating agent and at least one type of chlorine-containing starting compound selected from the group consisting of chlorine-containing alkanes represented by general formula (1) CX2YCHClCH2Z (where X, Y, and Z are each independently H, F, or Cl) and chlorine-containing alkenes represented by general formula (2) CH2YCCl=CZ2 (where X, Y and Z are each independently H, F, or Cl). The molar ratio of the chlorine-containing starting compound, represented by general formula (1) or (2), newly fed to a reactor inlet to the 2-chloro-3,3,3-trifluoropropene (HCFO-1233xf) of the components at a reactor outlet is less than 1.2.
