权利要求: What is claimed is:1. A composition comprising a chlorine-containing refrigerant blend; and a. a compressor lubricant comprising: i. an oil of lubricating viscosity comprising at least one oxygenate; and ii. at least one phosphorous additive.2. The composition of claim 1, wherein the at least one phosphorous additive is present at 0.1 to 4 wt% (or 0.1 to 3 wt%, or 0.2 to 1 wt%, or 0.3 to 0.6 wt%), based on a total weight of the compressor lubricant.3. The composition of claim 1 or 2, wherein the at least one phosphorous additive comprises a phosphate, phosphite, phosphonate, or mixtures thereof.4. The composition of any of the above claims, wherein the at least one phosphorous additive comprises an aryl phosphate or an aryl phosphate in combination with an alkenyl phosphite, for example a Ci6 - Cis alkenyl phosphite.5. The composition of any of the above claims, wherein the at least one phosphorous comprises butylated triphenyl phosphate, tricresyl phosphate, dimethyl octadecyl phosphonate, or mixtures thereof.6. The composition of any of the above claims, wherein the compressor lubricant further comprises at least one acid scavenger and/or at least one antioxidant (for example, ditertbutyl cresol) and/or at least one metal passivator (for example, benzotri azole).7. The composition of claim 6, wherein the acid scavenger is a hydrocarbyl substituted glycidol ether (for example, glycidyl epoxide).8. The composition of any of the above claims, wherein the chlorine-containing refrigerant blend comprises a chlorine-containing compound and a hydrofluoro olefin (“HFO”).9. The composition of claim 8, wherein the chlorine-containing refrigerant blend comprises R-514A.10. The composition of any claim 1 to 9, wherein the oxygenate comprises at least one alcohol, ester oil, ether oil, or combinations thereof.11. The composition of claim 10, wherein the oxygenate comprises at least one polyol ester, at least one polyalkylene glycol, at least one polyvinyl ether, or combinations thereof.12. The composition of claim 11, wherein the oxygenate comprises at least one polyol ester, for example a polyol ester derived from the reaction mixture of di-pen- taerythritol, heptanoic acid, iso-nonanoic acid, caprylic acid, or capric acid.13. The composition of any claim 1 to 12, wherein the oil of lubricating viscosity further comprises as at least one hydrocarbon oil.14. The composition of claim 13, wherein the at least one hydrocarbon oil is present at 0.1 to 25 wt% (or 5 to 25 wt%), based on a total weight of the oil of lubricating viscosity.15. The composition of claim 13 or 14, wherein the hydrocarbon oil is an aromatic hydrocarbon.16. The composition of claim 15, wherein the aromatic hydrocarbon is alkylbenzene.17. The composition of any claim 1 to 16, wherein the compressor lubricant has a viscosity grade of 46 to 170 at 40 °C as measured using ASTM D445.18. A refrigeration compressor charged with a chlorine-containing refrigerant blend and the compressor lubricant of any claim 1 to 17.19. The refrigeration compressor of claim 18, wherein the compressor is a centrifugal compressor.20. A method of reducing tin corrosion in a compressor system, the method comprising: a. adding at least one phosphorus containing additive to a compressor lubricant, wherein the compressor lubricant comprises:b. an oil of lubricating viscosity comprising at least one oxygenate; and wherein the compressor system contains a chlorine-containing refrigerant.21. The method of claim 20, wherein the tin corrosion is reduced as measured using ASHRAE 97. 22. The method of claim 21, 97wherein the tin corrosion is reduced as compared to a lubricant without the at least one phosphorus containing additive.23. The method of any claim 20 to 23, wherein wear in the compressor is also reduced.24. The method of claim 23, wherein the wear is reduced as measured using ASTM D4172 and/or ASTM D2783.25. The method of any claim 20 to 24, wherein at least one of steel, copper, or aluminum corrosion is also reduced.26. The method of any claim 20 to 25, wherein the compressor operates under anaerobic conditions. 27. The method of any claim 20 to 26, wherein the compressor is a centrifugal compressor.
