Acetic acid derivatives of the formula: ##STR1## and pharmaceutically acceptable alkali metal salts thereof, wherein R represents the radical ##STR2## in which R.sub.1 and R.sub.2, which may be the same or different, each represent an alkyl radical having from 1 to 4 carbon atoms, R.sub.3 represents a hydrogen atom or a methyl radical and n is an integer in the range of from 0 to 3 inclusive. They possess a competitive inhibitory activity with respect to .gamma.-aminobutyric .alpha.-ketoglutaric transaminase as well as antianoxic and anticonvulsant properties and they are useful for treating central neurological disorders whether resulting or not from cerebral ischemia.

A refrigerating machine oil composition suitable for a compressor using a hydrofluorocarbon as a refrigerant, which comprises 100 parts by weight of a polyol ester as a base oil, from 7.0 to 15.0 parts by weight of a phosphate, and from 0.2 to 3.0 parts by weight in total of a 1,2-epoxy-alkane and/or a vinylcyclohexene dioxide. The use of the refrigerating machine oil composition improves wear resistance of sliding portions of compressors and is free from the formation of sludges derived from the polyol ester used as a base oil of the oil composition. A rotary compressor using the oil composition is also disclosed.
