Problems solved by technology

However, among the many possible lubricating oils covered by the aforementioned U.S. patents, there are still lubricating oils that cannot simultaneously meet the requirements of low viscosity, low pour point, low Noack volatilization loss, and high non-polarity index characteristics. This also shows that the aforementioned The U.S. patent does not take into account all of the above feature requirements

Embodiment 1

[0041] The preparation methods of the base oils of Example 1 and Comparative Examples 1 to 8 are as follows.

[0042] base oil

[0043] Mix the monoester obtained from isotetracohol and heptanoic acid (abbreviated as isotetradecyl alcohol-C7) and the monoester prepared from isoformyl alcohol and heptanoic acid (abbreviated as Cetyl alcohol-C7), obtain the base oil of embodiment 1. Based on the total weight of the base oil as 100wt%, the weight range of the monoester (isotetracosanol-C7) prepared from isotetracosyl alcohol and heptanoic acid is 40 wt%. The weight range of the monoester (isobehenyl alcohol-C7) prepared by alcohol and heptanoic acid is 60wt%.

[0044] base oil

[0045] The base oils of Comparative Examples 1, 6-7 are made of monoester [isotridecyl stearate (isotridecyl stearate)] or diester [diisodecyl adipate (diisodecyl adipate)] listed in Table 1 respectively. Or diisotridecyl adipate (diisotridecyl adipate)].

Abstract

A base oil and lubricating oil comprising at least two monoesters. Each monoester is prepared from a monoalcohol and a monocarboxylic acid. Wherein, the unit alcohol is C 16 ~C 36 Saturated branched chain aliphatic unit alcohol, the monocarboxylic acid is C 5 ~C 10 a saturated aliphatic monocarboxylic acid, and said monoester is prepared from the same monocarboxylic acid. The lubricating oil contains the aforementioned base oil. The base oil of the present invention can simultaneously meet the characteristics of low viscosity, low pour point, low Noack volatilization loss and high NPI, thereby achieving the purpose of energy saving and carbon reduction.

Description

technical field [0001] The present invention relates to a base oil and a lubricant comprising the base oil, in particular to a base oil comprising an ester compound and a lubricating oil comprising the base oil. Background technique [0002] In order to achieve the goal of energy saving and carbon reduction, future automotive engine lubricating oils need to develop in line with the GF-6 specification formulated by the International Lubricant Standardization and Certification Committee (ILSAC). [0003] In order to better meet the GF-6 specification, the lubricating oil and the base oil it contains must simultaneously meet low viscosity, low pour point (P.P.), low Noack evaporation loss (evaporation loss) and high non-polarity index (nonpolarity index). -polar index; referred to as NPI) characteristics. Among them, the low pour point can make the lubricating oil not need to use additional heating equipment to maintain its fluidity in cold environment. In addition, the low N...
