Embodiment

[0082] EXAMPLES - PREFERRED EMBODIMENTS

[0083] In order to conduct tests to demonstrate the desired properties of the oils of the present invention, an oil was synthesized, designated "Sample 1", containing an alkylbenzene compound having an alkane side chain of 8 carbon atoms :

[0084]

[0085] In addition, an antiwear (AW) additive was added to the "Sample 1" oil, defined as follows:

[0086] Chemical name: butylated triphenyl phosphate

[0087] Chemical formula: mixture

[0088] Chemical class: aryl phosphate

[0089] Dosage: 2.0±0.3% (m / m), relative to the total weight of oil

[0090]

[0091] The inventive oils described above were compared with the commercial sample LAB 240A (alkylbenzene with paraffin side chains, having 10-13 carbon atoms, average molecular weight 238-245), and with another paraffin-containing A lubricating oil of an alkylbenzene compound having a side chain of 10 carbon atoms, referred to as "Sample 2":

[0092]

[0093] The alkylbe...

Abstract

The present invention discloses an oil comprising at least one alkyl aromatic compound wherein the oil viscosity is lower than 3.0 cSt at the temperature of 40 °C. The oil of the present invention shows a lower viscosity variation as a function of the temperature, what contributes to reduce the cooling system equipment wear and increase the equipment operation lifetime, for example, the operation lifetime of the cooling compressors. It also an object of the present invention a composition comprising said oil in combination with at least one fluid of the hydrocarbon (HC) type and its uses in mechanical equipments and mechanical equipments made with said oil and / or composition.

Description

technical field [0001] The present invention relates to an oil with improved lubricity and increased coefficient of performance, to a lubricating composition and its use, and to a cooling machine. More specifically, the oils of the present invention contain an alkylaromatic compound and are especially useful in the preparation of lubricating compositions and in high performance improved coolers. The invention is particularly applicable to hermetic compressors, which may be of the type used in small, domestic, commercial or even industrial cooling systems, preferably run with HC (hydrocarbon) type coolants. The invention further discloses a high-performance cooler containing the lubricating oil component. Background technique [0002] Traditional coolants used in domestic coolers were CFC-based compounds until the mid-1990s. However, when the use of the compound is proven to damage the ozone layer in the atmosphere, the use of the compound is limited and restricted by the p...
