PROBLEM TO BE SOLVED: To provide a new heterocyclic ring-containing compound having a superior lubricant performance and a lubricant composition. SOLUTION: This heterocyclic ring-containing compound is represented by general formula (1). In the formula (1), D represents a heterocyclic ring residue having a 5- to 7-membered ring structure and substituted with (m+n) of substituents; X represents a divalent linking group consisting of a single bond, NR<SP>3</SP>group (R<SP>3</SP>represents hydrogen atom or a 1-30C alkyl group), an oxygen atom, a sulfur atom, a carbonyl group, a sulfonyl group or a combination thereof; R<SP>1</SP>represents an alkyl group, an alkenyl group, an alkynyl group, an aryl group or a heterocyclic group, which may be substituted or unsubstituted, R<SP>2</SP>represents a halogen atom, a hydroxyl group, an unsubstituted amino group, a mercapto group, a cyano group, a sulfide group, a carboxy group or salt thereof, a sulfo group or salt thereof, a hydroxyamino group, an ureido group or an urethane group; m represents 1 or 2, and n represents an integer of≥1. This lubricant composition contains the heterocyclic ring-containing compound. COPYRIGHT: (C)2003,JPO |
