Abstract
Official abstract text for this publication.
This application relates to branched diester compositions that can be used as a base stock for lubricant applications, or as a base stock blend component for use in a finished lubricant or for particular applications, and methods for making the same.
First claim
Opening claim text (preview).
The invention claimed is: 1. A lubricant base stock diester composition comprising octyl 9-(octanoyloxy) decanoate. 2. The lubricant base stock diester composition of claim 1 , wherein the composition has a kinematic viscosity at 100° C. of about 3.2 cSt, a pour point of about −33° C., and a Noack volatility of about 10.3%. 3. A lubricant base stock diester composition comprising 10-(octanoyloxy)decan-2-yl octanoate. 4. The lubricant base stock diester composition of claim 3 , wherein the composition has a kinematic viscosity at 100° C. of about 3.12 cSt, a pour point of about −33° C., and a Noack volatility of about 10.6%. 5. A lubricant base stock diester composition comprising 2-ethylhexyl 9-(octanoyloxy)decanoate. 6. The lubricant base stock diester composition of claim 5 , wherein the composition has a kinematic viscosity at 100° C. of about 3.2 cSt, a pour point of about −45° C., and a Noack volatility of about 15%. 7. A lubricant base stock diester composition comprising 10-[(2-ethylhexyl)oxy]-10-oxodecan-2-yl dodecanoate. 8. The lubricant base stock diester composition of claim 7 , wherein the composition has a kinematic viscosity at 100° C. of about 4.0 cSt, a pour point of about −40° C., and a Noack volatility of about 5.5%.
