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.

b) HFO-1234ze, HFO-1243zf, and HFC-245cb,
c) one of HCFC-253fb or HCFO-1233xf, and optionally, at least one additional compound selected from HCFC-243db, HCFC-244db, HFC-245fa, HCFO-1233zd, HCFC-234ab, HCFC-243fa, ethylene, HFC-23, CFC-13, HFC-143a, HFC-152a, HFC-236fa, HCO-1130, HCO-1130a, HCFC-133a, HCFC-254fb, HFC-1141, HCFO-1242zf, HCFO-1223xd, HCFC-233ab, HCFC-226ba, and HFC-227ca.

2. The composition of claim 1 wherein said at least one additional compound comprises HFC-143a.

3. The composition of claim 1 further comprising HCFC-244bb.

4. The composition of claim 1 , wherein the total amount of HCFC-1131 or HFO-1336 and said at least one additional compound is greater than 0 and less than 1 mole percent based on the total amount of the composition.

5. 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.

6. 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 .

7. The heat transfer system of claim 6 wherein the system comprises a mobile refrigeration apparatus.

8. A composition comprising (a) HFO-1234yf, (b) HCFC 1131 (c) HFC-245cb, and (d) additional compounds selected from HFO-1336, HCFC-253fb, HCFC-234ab, CFC-13, HCO-1130, HCO-1130a, HCFC-133a, HCFO-1242zf, HCFC-233ab, and HCFC-226ba, HCFO-1233xf, HCFO-1233zd, HCFO-1223xd and HCFC-243fa, wherein the total amount of the additional compounds, including HFC-245cb, is greater than 0 and less than about 1 mole percent based on the total amount of the composition.

9. The composition of claim 8 wherein one of said additional compounds comprises HCFC-253fb.

10. The composition of claim 8 further comprising HFC-143a.

11. The composition of claim 8 further comprising HCFC-244bb.

12. The composition of claim 8 wherein one of said additional compounds comprises HCFO-1233xf.

13. A method for carrying heat from a heat source to a heat sink wherein a media comprising the composition of claim 8 is used as heat transfer fluid.

14. 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 8 .
