##STR00001## in which R.sup.1 a straight or branched C1-C24 alkyl group; R.sup.2 is a C1-C8 alkyl group; R.sup.3 is a C1-C8 alkyl group.

The invention also relates to industrial products such as additive blends, engine oils and polymer compositions comprising this compound of the general formula (I) and to the use the compound of the general formula (I) as an additive such in industrial products such as additive blends, engine oils and polymer compositions.

Provided is a an additive or composition for imparting lubricity which has high lubricity, is excellent in low-corrosion property, low-temperature fluidity, thermal conductivity, thermal stability, and oxidative stability, and has high flashing point. The lubricant according to the present invention is an additive or composition, wherein the following components (A) an amine or an ammonium compound; and (B) an acid or a salt thereof, have been added therein, wherein at least one of the components (A) and (B) contains a hydrogen-bonding functional group.

A sofa bed sliding system (100, 200, 300, 400, 500, 600, 700) for a sofa bed (1,1) is provided. The sliding system is forming a connection between a moveable sofa bed part (3, 3) and an associated frame structure (10, 10), wherein said sliding system (100, 200, 300, 400, 500, 600, 700) comprises at least one sliding surface (110, 210, 310, 410, 510, 610) being coated with a lacquer comprising a resin, wherein said lacquer in turn is at least partly coated with a lipophilic composition coating to provide a slide layer with a lowered friction.

The present invention relates to a lubricant base oil containing an aromatic ester lubricant represented by Chemical Formula 1 and to a method for preparing the aromatic ester lubricant. By containing an aromatic ester lubricant, the lubricant base oil exhibits an excellent dispersibility and fluidity and is ecofriendly due to a high biodegradability. In addition, the method for preparing the aromatic ester lubricant does not generate such toxic substances as S, N, aromatic compounds and heavy metals and enables an easy control of the physical properties of a desired lubricant base oil by selecting a suitable alcohol compound to be introduced for an esterification reaction.

Implementations of wax ester compositions may include: a product of transesterfying oleyl oleate, stearyl stearate, and behenyl behenate using one of a chemical or an enzyme catalyst. The ratio of the oleyl oleate to stearyl stearate to behenyl behenate in the mixture prior to transesterification is one of 65%/23%/12%, 56%/29%/15%, or 36%/34%/30%, respectively, measured by weight. The product may demonstrate a substantially equivalent physical property to a physical property of a transesterified wax ester composition including a jojoba ester.

A lubricating composition comprising a base oil of lubricating viscosity and one or more lubricant additives, wherein the base oil comprises or consists of a base stock which comprises or consists of at least one isoprenoid compound comprising: (i) one or two oxygen-containing moieties independently selected from ether and ester moieties; (ii) a first acyclic isoprenoid moiety containing 1 to 5 isoprenyl units; and (iii) optionally, a second acyclic isoprenoid moiety containing 1 to 5 isoprenyl units with the proviso that at least one isoprenoid moiety contains 3 to 5 isoprenyl units where the isoprenoid compound contains a single ether moiety.

The invention provides a lubricating composition containing an antiwear agent and an oil of lubricating viscosity. The invention further relates to the use of the lubricating composition in an internal combustion engine, or a driveline device.

Stable water-in-oil emulsions suitable for use as fire-resistant aerosol multipurpose lubricants. The water-in-oil emulsion comprises a synthetic ester base oil, compatible invert emulsifier, water, and a preservative. The aerosol apparatus employs a larger than standard stem orifice to produce a non-flammable aerosol.
