POLYOL AND COMPLEX ESTERS FOR USE WITH, IN PARTICULAR, FLUORINATED REFRIGERANTS |
摘要 |
The invention concerns a refrigerant composition which comprises a chlorine-free hydrofluorocarbon based refrigerant and, mixed with the refrigerant, a lubricant comprising a polyol ester. According to the invention the polyol ester comprises an ester of 2-butyl-2-ethyl-1,3-propane diol, the carboxylic acid residue of which is derived from a linear or branched C4...C18-carboxylic acid or an anhydride thereof, or it is derived from a mixture of linear or branched C4...C18-carboxylic acids or anhydrides thereof. The present invention also concerns novel complex esters of 2-butyl-2-ethyl-1,3-propanediol, which contain residues of mono- or bivalent carboxylic acids. The novel esters exhibit good solubility in fluorinated hydrocarbons and excellent lubricating properties.
