A working fluid composition for use in a refrigeration system which comprises a refrigerating oil comprising a compound having one or more ketone groups in the molecular structure as a base oil and a hydrofluorocarbon.
The nickel(II) Schiff base complexes with 2-methylbutyl or 2-methylpentyl groups and their benzoyl derivatives have been prepared and characterized by H-1 and C-13 NMR spectroscopy. The structure of the benzoyl derivatives in chloroform solution can be estimated as follows: the donor set of N2O2 has a square planar coordination, the benzoyl substituents are perpendicular to the chelate plane and the long alkyl chains (2-methylbutyl or 2-methylpentyl groups) move segmentally to approach the benzoyl substituents.
