(JA) 潤滑油
(EN) Disclosed is a lubricating oil which has a low viscosity and a low vapor pressure at the same time, is free from a risk of inflammation and excellent in heat resistance. The lubricating oil has friction characteristics equivalent to those of the conventional hydrocarbon lubricating oils, and can be used for a long time under extremely severe conditions such as at high temperatures in vacuum condition. The lubricating oil contains, as a base oil, an ionic liquid which is composed of cations and anions and has an ion concentration of not less than 1 mol/dm3.
(FR) L'invention concerne un lubrifiant à faible viscosité et à faible pression de vapeur à la fois, dépourvu du risque d'inflammation et à excellente résistance à la chaleur. Le lubrifiant comporte des caractéristiques de friction équivalentes aux lubrifiants hydrocarbonés classiques, et peut être utilisé longtemps et dans des conditions extrêmes, telles qu'à des températures élevées en condition de vide. Le lubrifiant contient, comme huile de base, un liquide ionique composé de cations et d'anions et possède une concentration ionique non supérieure à 1 mol/dm3.
(JA)  低粘度であっても蒸気圧が低く、引火の危険性もなく、さらに耐熱性に優れ、従来の炭化水素系潤滑油と比べて何ら遜色のない摩擦特性を有し、高温下、真空下などの極めて厳しい条件の下でも長期間使用することができる潤滑油を提供すること。  基油として、カチオンとアニオンから構成され、イオン濃度が1mol/dm3以上であるイオン性液体を含む潤滑油である。
