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.
Opening claim text (preview).
The invention claimed is: 1. A method of making a diester lubricant base stock compound, comprising: reacting methyl 9-decenoate with an alcohol of formula R—OH, wherein R is a C 1 -C 36 alkyl group, to form a monoester, wherein the monoester is a compound of formula and reacting the monoester with an acid of formula R 1 —COOH, wherein R 1 is a C 1 -C 36 alkyl group, to form a diester lubricant base stock compound of formula 2. The method of claim 1 , wherein R is 2-ethylhexyl, isobutyl, n-hexyl, or n-octyl. 3. The method of claim 1 , wherein R 1 is n-heptyl, n-nonyl, or n-undecyl. 4. The method of claim 2 , wherein R 1 is n-heptyl, n-nonyl, or n-undecyl. 5. A method of making a diester lubricant base stock compound, comprising: reacting methyl 9-decenoate with an alcohol of formula R—OH, wherein R is a C 1 -C 36 alkyl group, to form a first monoester, wherein the monoester is a compound of formula reacting the first monoester with formic acid, followed by hydrolysis, to form a second monoester, wherein the second monoester is a compound of formula and reacting the second monoester with an acid of formula R 1 —COOH, wherein R 1 is a C 1 -C 36 alkyl group, to form a diester lubricant base stock compound of formula 6. The method of claim 5 , wherein R is 2-ethylhexyl, isobutyl, n-hexyl, or n-octyl. 7. The method of claim 5 , wherein R 1 is n-heptyl, n-nonyl, or n-undecyl. 8. The method of claim 6 , wherein R 1 is n-heptyl, n-nonyl, or n-undecyl.
