Abstract

Provided is a composition comprising (a) at least one halogenated compound selected from the group consisting of C 3 -C 5 hydrofluoroolefin, CF 3 I, and combinations thereof, and (b) an effective stabilizing amount of a sesquiterpene selected from the group consisting of farnesol, farnesene, and mixtures thereof.

Claims (8)

1. A composition consisting essentially of about 95 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 5 weight percent farnesene.

2. The composition of claim 1 consisting essentially of about 99 to about 99.7 weight percent HFO-1234yf and about 0.3 to about 1 weight percent farnesene.

3. The composition of claim 1 having a temperature of greater than about 50° C.

4. A method for chemically stabilizing a refrigerant composition comprising HFO-1234yf comprising:

mixing HFO-1234yf with farnesene to form a mixture consisting essentially of about 95 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 5 weight percent farnesene.

5. A method for chemically stabilizing a solvent comprising HFO-1234yf comprising the steps of:

a. mixing HFO-1234yf with farnesene to form a mixture consisting essentially of about 95 to about 99.9 weight percent HFO-1234yf and about 0.1 to about 5 weight percent farnesene; and

b. increasing the temperature of the solvent to at least 50° C.
