PROCESS FOR PREPARING 3,3,3-TRIFLUOROPROP-1-ENE
The present application provides a process of preparing 3,3,3-trifluoroprop-1-ene, comprising reacting 3-chloro-1,1,1-trifluoropropane with a base in an aqueous solvent component in the absence of a phase transfer catalyst.
1 . A process for identifying a major refrigerant component, the process comprising adding at least one of about 0.01 mole percent or less 2-chloro-3,3,3-trifluoropropene (1233xf) and about 0.01 mole percent or less 1,1,1,3-tetrafluoropropane (254fb) to the major refrigerant component.
2 . A composition comprising:
a refrigerant lubricant selected from one of mineral oils, alkylbenzenes, synthetic paraffins, synthetic naphthenes, poly(alpha)olefins, polyol esters (POE), polyalkylene glycols (PAG), polyvinyl ethers (PVE), or perfluoropolyethers (PFPE), or mixtures thereof; and
at least one of 3,3,3-trifluoroprop-1-ene (1243zf), 2-chloro-3,3,3-trifluoropropene (1233xf), 1,1,1,3-tetrafluoropropane (254fb), and 1,1,1-trifluoro-2,3-dichloropropane (243db).
3 . The composition of claim 2 , further comprising 2,3,3,3-tetrafluoropropene (HFO-1234yf).
4 . The composition of claim 2 , comprising about 0.01 mole percent or less of 1,1,1,3-tetrafluoropropane (254fb).
5 . The composition of claim 2 , comprising about 0.1 percent or less of 2-chloro-3,3,3-trifluoropropene (1233xf), as measured by GC-MS.
6 . The composition of claim 2 , comprising about 0.05 to about 0.1 mole percent 2-chloro-3,3,3-trifluoropropene (1233xf) and about 0.01 to about 0.05 mole percent 1,1,1,3-tetrafluoropropane (254fb).
7 . The composition of claim 2 , comprising about 0.05 to about 0.07 mole percent 2-chloro-3,3,3-trifluoropropene (1233xf) and about 0.01 to 0.02 mole percent 1,1,1,3-tetrafluoropropane (254fb).
8 . The composition of claim 2 , the composition comprising 2,3,3,3-tetrafluoropropene (HFO-1234yf), about 0.01 mole percent or less of 1,1,1,3-tetrafluoropropane (254fb), and about 0.1 percent or less of 2-chloro-3,3,3-trifluoropropene (1233xf) as measured by GC-MS.
