Abstract
Official abstract text for this publication.
An ester compound is represented by the following formula (1). In the formula: R 1 and R 2 each independently represent an alkyl group having 5 to 18 carbon atoms; R 3n represents a hydrogen atom or an alkyl group having at most 5 carbon atoms; R 4n represents hydrogen or CH 2 OR 5n ; R 5n represents an alkyl group having 5 to 18 carbon atoms; and n represents an integer of 1 to 3.
First claim
Opening claim text (preview).
The invention claimed is: 1. An ester compound according to formula (2): wherein: each of R and R′ independently represents an alkyl group having 5 to 18 carbon atoms; and R″ represents hydrogen or an alkyl group having at most 5 carbon atoms. 2. The ester compound according to claim 1 , wherein a total number of carbon atoms in the ester compound is 24 to 42. 3. The ester compound according to claim 1 , wherein R″ represents an ethyl group or a propyl group. 4. A lubricant base oil, comprising the ester compound according to claim 1 . 5. A lubricant, comprising the lubricant base oil according to claim 4 . 6. The lubricant according to claim 5 , wherein the lubricant is suitable for an oil-impregnated bearing or a fluid dynamic bearing. 7. A grease base oil, comprising the ester compound according to claim 1 . 8. A grease, comprising the grease base oil according to claim 7 . 9. An ester compound according to formula (3): wherein: each of R and R′ independently represents an alkyl group having 5 to 18 carbon atoms; and a total number of carbon atoms in the ester compound is 24 to 40. 10. A lubricant base oil, comprising the ester compound according to claim 9 . 11. A lubricant, comprising the lubricant base oil according to claim 10 . 12. The lubricant according to claim 11 , wherein the lubricant is suitable for an oil-impregnated bearing or a fluid dynamic bearing. 13. A grease base oil, comprising the ester compound according to claim 9 . 14. A grease, comprising the grease base oil according to claim 13 . 15. A manufacturing intermediate selected from the group consisting of 5-(2-ethylhexyloxy)-2,4-diethyl-1-pentanol, 5-nonyloxy-2,4-diethyl-1-pentanol, 5-decyloxy-2,4-diethyl-1-pentanol, 5-undecyloxy-2,4-diethyl-1-pentanol, and 5-dodecyloxy-2,4-diethyl-1-pentanol.
