Abstract
Disclosed are compositions comprising at least one iodocarbon compound and preferably at least one stabilization agent comprising a diene-based compound. These compositions are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents.
Claims26
A heat transfer composition comprising:
- (A) at least one iodocarbon;
- and
- (B) at least one diene-based compound in an amount effective to stabilize said at least one iodocarbon against degradation.
-8. (canceled)
-12. (canceled)
-21. (canceled)
An iodocarbon-containing composition stabilized against decomposition of carbon-iodine bonds comprising:
- (C) at least one iodocarbon;
- and
- (D) at least one diene-based composition in an amount effective to stabilize said at least one iodocarbon against degradation.
(canceled)
-28. (canceled)
A method of stabilizing a composition comprising providing an iodocarbon containing composition and contacting said composition with a diene-based compound.
A heat transfer composition comprising:
- (A) at least one fluoroalkene of formula I:
- XCFzR3-z (I)
- where x is a c2 or a c3 unsaturated, substituted or unsubstituted, alkyl radical, r is independently cl, f, br, i or h, and z is 1 to 3;
- (B) at least one iodocarbon.
(canceled)
-65. (canceled)
A heat transfer composition comprising:
- (E) at least one iodocarbon;
- (F) at hydrofluorocarbon;
- and
- (G) at least one diene-based stabilizer.
