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.

First claim

What is claimed is:

1. A heat transfer system comprising at least one member selected from the group consisting of air conditioners, heat pumps, mobile refrigerators and mobile air conditioning units; and a working fluid composition comprising HFO-1234yf, HFO-1234ze, HFO-1243zf and at least one additional compound comprising HCFC-1131.

2. The system of claim 1 containing less than about 1 weight percent of the at least one additional compound.

3. The system of claim 1 wherein said composition further comprises HCFO-1233xf.

4. The system of claim 1 wherein said composition further comprises HCFC-244bb.

5. The system of claim 2 wherein said additional compound comprises HCFO-1233xf and HCFC-1131.

6. The system of claim 5 wherein the amount of the at least one additional compound is greater than 0 and less than about 1 weight percent.

7. A heat transfer system comprising at least one member selected from the group consisting of air conditioners, heat pumps, mobile refrigerators and mobile air conditioning units; and a working fluid composition comprising HFO-1234yf, HFO-1234ze, HFO-1243zf, HCFC-1131 and HFC-143a.

8. A heat transfer system comprising at least one member selected from the group consisting of air conditioners, heat pumps, mobile refrigerators and mobile air conditioning units; and a working fluid composition comprising HFO-1234yf, HFO-1234ze, HFO-1243zf, HCFC-1131, HFC-143a and at least one additional compound selected from the group consisting of HCFC-244db, HFC-245cb and HFC-245fa.

9. The system of claim 8 wherein the amount of the at least one additional compound is greater than 0 and less than about 1 weight percent.

10. The system of claim 9 wherein the additional compound comprises HCFC-244bb.

11. The system of claim 9 wherein the additional compound comprises HFC-245cb.

12. The system of claim 9 wherein the additional compound comprises HFC-245fa.
