Haloolefin-based composition

Abstract

The present invention provides a highly stable haloolefin-based composition that inhibits decomposition or oxidization. The haloolefin-based composition comprising (a) a haloolefin; (b) at least one compound selected from the group consisting of HFC-1234ze, HFC-254eb, HFC-1243zf, HFC-245eb, HFC-245fa, HC-245cb, HFC-236ea, HFC236fa, HFC1225ye, 3,3,3-trifluoropropine, HFC-23, HFC-32, HFC-125, HFC-143a, HFC-134a, FC-1216, HCFO-1233xf, HCFO-1233zd, HCFO-1232xf, HCFO-1223xd, and chloromethane; and (c) water.

1 . A haloolefin-based composition comprising:
 (a) at least one haloolefin selected from the group consisting of HFO-1234yf, HFO-1234ye, HFO-1234yc, HFO-1225ye, HFO-1225zc, HFO-1243zf, HFO-1336mzz, and HFO-1429myz;   (b) HFO-1234ze; and   (c) water in an amount of 200 ppm by weight or less based on the total amount of the (a) haloolefin.   
     
     
         2 . The composition according to  claim 1 , which further comprises (d) oxygen. 
     
     
         3 . The composition according to  claim 2 , wherein the amount of the (d) oxygen is 0.35 mol % or less based on the total amount of the (a) haloolefin. 
     
     
         4 . The composition according to  claim 1 , wherein the (a) haloolefin is HFO-1234yf. 
     
     
         5 . (canceled) 
     
     
         6 . The composition according to  claim 1 , which further comprises (e) at least one component selected from the group consisting of polyalkyleneglycol and polyolether. 
     
     
         7 - 9 . (canceled)
