1. A refrigerant composition for use in a refrigeration system comprising:
a) water, an alcohol and compound of the formula 1, or mixtures thereof:wherein A is selected from N, P or S; and wherein
i) when A is N, each R1, R2, R3 and R4 independently form a double bond with N and an adjacent R1, R2, R3 or R4 group or are each independently selected from the group consisting of hydrogen, (C1-C20)alkyl, aryl, (C3-C10)heterocyclyl, (C3-C10)cycloalkyl, (C3-C10)heterocyclyl(C1-C8)alkyl, aryl(C1-C8)alkyl, hetero aryl and hetero aryl(C1-C8)alkyl group that may be unsubstituted or substituted by one or two halo, nitro, trifluoromethyl, trifluoromethoxy, methoxy, carboxy, —NH2, —OH, —SH, —NHCH3, —N(CH3)2, cyano, —SMe, —SO3H, —P((C1-C5)alkyl)2 and —P(O)(OEt)2; or wherein R1, R2 and R3 together with N form a heteroaromatic or R1 and R2 together with N form a heterocyclic ring each unsubstituted or substituted by a group selected from halo, nitro, trifluoromethyl, trifluoromethoxy, methoxy, carboxy, —NH2, —OH, —SH, —NHCH3, —N(CH3)2, —SMe, cyano, (C1-C3)alkyl, aryl, (C3-C6)cycloalkyl, aryl(C1-C3)alkyl and heteroaryl; ii) when A is S, R1, R2, R3 and R4 are each independently selected from the group consisting of hydrogen, (C1-C20)alkyl, aryl, (C3-C10)heterocyclyl, (C3-C10)cycloalkyl, (C3-C10)heterocyclyl(C1-C8)alkyl, aryl(C1-C8)alkyl, hetero aryl and heteroaryl(C1-C8)alkyl group that may be unsubstituted or substituted by one or two halo, nitro, trifluoromethyl, trifluoromethoxy, methoxy, carboxy, —NH2, —OH, —SH, —NHCH3, —N(CH3)2, cyano, —SMe, —SO3H, —P((C1-C5)alkyl)2 and —P(O)(OEt)2; and iii) when A is P, R1, R2, R3 and R4 are each independently selected from the group consisting of hydrogen, (C1-C20)alkyl, aryl, (C3-C10)heterocyclyl, (C3-C10)cycloalkyl, (C3-C10)heterocyclyl(C1-C8)alkyl, aryl(C1-C8)alkyl, heteroaryl and heteroaryl(C1-C8)alkyl group that may be unsubstituted or substituted by one or two halo, nitro, trifluoromethyl, trifluoromethoxy, methoxy, carboxy, —NH2, —OH, —SH, —NHCH3, —N(CH3)2, cyano, —SMe, —SO3H, —P((C1-C5)alkyl)2 and —P(O)(OEt)2; and b) at least one gas refrigerant that can undergo reversible chemical reaction during refrigeration cycles. |
