Title:
BASE OIL FOR REFRIGERATION OIL COMPOSITION, REFRIGERATION OIL COMPOSITION AND COMPOSITION FOR COOLING
Document Type and Number:
WIPO Patent Application WO/2016/206246
Kind Code:
A1
Abstract:
A base oil for a refrigeration oil composition and refrigeration oil composition. The base oil comprises an alkylbenzene oil and an ester oil. The ratio of the 120˚C kinetic viscosity of the base oil to the 40˚C kinetic viscosity thereof is 0.23-0.30. A base oil having a viscosity overly decreasing with the increase of the temperature is formed by combining an alkylbenzene oil and an ester oil having a low viscosity and high viscosity index for use and adjusting the ratio of the 120˚C kinetic viscosity of the base oil to the 40˚C kinetic viscosity thereof.
