Abstract:
1. A heat transfer composition comprising: (a) at least one iodocarbon; (b) at least one refrigerant compound other than said iodocarbon; (c) a first stabilizing compound selected from the group consisting of dienes having at least four carbon atoms; (d) a second stabilizing compound selected from the group consisting of: (1) diene-based compounds having at least two carbon-carbon double bonds and at least four carbon atoms, different from (c); (2) epoxy compounds selected from compounds according to Formulas (E1) and (E2): where R 1 is an aliphatic radical having at least 3 carbon atoms; R 2 is an aliphatic radical having 4 or 5 carbon atoms or a polycyclic aromatic radical; (3) phosphites according to formula P1 below: where each R is independently a phenyl radical or a carboxylate radical having at least 6 but less than 15 carbon atoms; (4) unhindered or mildly hindered phenols; and (5) combinations of any two or more of these, said stabilizer compound(s) being present in an amount effective to stabilize said at least one iodocarbon against degradation; and (e) 30 wt % to about 50 wt % of at least one lubricant.
