Abstract

Disclosed are compositions comprising HCFC-243db, HCFO-1233xf, HCFC-244db and/or HFO-1234yf and at least one additional compound. For the composition comprising 1234yf, the additional compound is selected from the group consisting of HFO-1234ze, HFO-1243zf, HCFC-243db, HCFC-244db, HFC-245cb, HFC-245fa, HCFO-1233xf, HCFO-1233zd, HCFC-253fb, HCFC-234ab, HCFC-243fa, ethylene, HFC-23, CFC-13, HFC-143a, HFC-152a, HFC-236fa, HCO-1130, HCO-1130a, HFO-1336, HCFC-133a, HCFC-254fb, CHF=CHCl, HFO-1141, HCFO-1242zf, HCFO-1223xd, HCFC-233ab, HCFC-226ba, and HFC-227ca. Compositions comprising HCFC-243db, HCFO-1233xf, and/or HCFC-244db are useful in processes to make HFO-1234yf. Compositions comprising HFO-1234yf are useful, among other uses, as heat transfer compositions for use in refrigeration, air-conditioning and heat pump systems.

2. The composition of claim 1 wherein said additional compound comprises HCFO-1233xf.

3. The composition of claim 1 wherein said additional compound comprises HCFC-HFC-254eb.

4. The composition of claim 1 wherein said additional compound further comprises HFC-143a.

5. The composition of claim 1 wherein said additional compound comprises HCFC-244bb.

6. A composition comprising HFO-1234yf, HFO-1234ze, HFO-1243zf, HCFC-1131, HFC-152a and optionally HFC-23.

7. A method for carrying heat from a heat source to a heat sink wherein a media comprising the composition of claim 1 is used as heat transfer fluid.

8. A heat transfer system comprising at least one member selected from the group consisting of air conditioners, freezers, refrigerators, heat pumps, water chillers, flooded evaporator chillers, direct expansion chillers, walk-in coolers, heat pumps, mobile refrigerators, mobile air conditioning units and combinations thereof; and wherein the system comprises a working fluid comprising the composition of claim 1 .

9. The heat transfer system of claim 8 wherein the system comprises a mobile refrigeration apparatus.

10. A method for carrying heat from a heat source to a heat sink wherein a media comprising the composition of claim 9 is used as heat transfer fluid.

11. A method for carrying heat from a heat source to a heat sink wherein a media comprising the composition of claim 6 is used as heat transfer fluid.

12. The compositions of any of claims 1 - 6 further comprising HCFC-253fb.
