Document Type and Number:
WIPO Patent Application WO/1996/011246
Kind Code:
A1
Abstract:
A refrigerator oil composition prepared by blending a base oil comprising a mineral or synthetic oil with at least one member selected from the group consisting of metal salts of inorganic phosphoric acid (e.g. potassium phosphate), amine salts of inorganic phosphoric acid (e.g. octylamine salt of phosphoric acid), metal salts of organic phosphoric acid (e.g. dipotassium lauryl phosphate), amine salts of organic phosphoric acid (e.g. monooctylamine salt of dioleyl phosphate), metal salts of organic phosphonic acid (e.g. dipotassium oleylphosphonate), amine salts of organic phosphonic acid (e.g. octylamine salt of dilaurylphosphonic acid), metal salts of organic phosphorous acid (e.g. sodium dioleyl phosphite), and amine salts of organic phosphorous acid (e.g. oleylamine salt of dioleyl phosphite). The composition has an excellent lubricating performance, improves the lubricity of the interface between an aluminum material and a steel material, can inhibit seizure and wear, and is suitable as a lubricating oil for refrigerators using a hydrochlorofluorocarbon refrigerant which does not cause environmental pollution, such as R134a.
