STABILIZER AND INHIBITOR FOR CHLOROPROPENES, SUCH AS TETRACHLOROPROPENE 1,1,2,3-TETRACHLOROPROPENE (1230xa), USED IN THE MANUFACTURE OF 2,3,3,3-TETRAFLUOROPROPENE (1234yf)

摘要

The present invention relates in part to a method of stabilizing chloropropenes, such as 1,1,2,3-tetrachloropropene, otherwise known to decompose and degrade, and to the resulting stabilized chloropropene, using a morpholine compound and/or a trialkyl phosphate compound as defined herein. Such stabilized chloropropenes are useful in the manufacture of hydrofluoroolefins such as 2,3,3,3-tetrafluoroprop-1-ene (1234yf).
