A lubricating composition containing an organic molybdenum compound having excellent oxidation stability that provides lubricity for long periods of time is provided.
The lubricant comprises a molybdenum amine compound obtained by reacting a compound containing a hexavalent molybdenum atom with an amine represented by the following formula (1):
where each of R1 to R3 represents a hydrogen atom and/or a hydrocarbon group having one or more carbon atoms, and at least one of R1 to R3 is a chain hydrocarbon group having 14 or more carbon atoms, or the following formula (2)
wherein R4 represents a chain hydrocarbon group having 10 or more carbon atoms, s represents 0 or 1, X and/or Y represents a hydrogen atom, a hydrocarbon group having at least one carbon atom, an alkanol group having 2 to 4 carbon atoms or an alkyl amino group having at least one carbon atom, and X and Y are not hydrogen atoms or hydrocarbon groups at the same time when s is 0. A lubricating composition containing the lubricant is also provided.
本发明提供了一种含有有机钼化合物的润滑组合物,该化合物具有出色的氧化稳定性,可长时间提供润滑。
该润滑剂包含一种钼胺化合物,该化合物是由含有六价钼原子的化合物与下式(1)所代表的胺反应而得:
其中 R1 至 R3 各代表一个氢原子和/或一个具有一个或多个碳原子的烃基,且 R1 至 R3 中至少有一个是具有 14 个或更多碳原子的链烃基,或下式 (2)
其中 R4 代表具有 10 个或更多碳原子的链状烃基,s 代表 0 或 1,X 和/或 Y 代表氢原子、具有至少一个碳原子的烃基、具有 2 至 4 个碳原子的烷醇基或具有至少一个碳原子的烷基氨基,当 s 为 0 时,X 和 Y 同时不是氢原子或烃基。 还提供了一种含有该润滑剂的润滑组合物。
