Study the Efficiency of Some Esters Based on 2- Ethyl Hexanoic Acid as Synthetic Lubricants

Esters have many important properties, such as biodegradation, low toxicity, good thermal stability and excellent solvability, because these features are definitely the most versatile of the various types of base fluids currently available and can be modified to provide unique physical and chemical properties that can be designed to meet the lubricant industry's challenges. In this article, Reaction was prepared by various branched synthetic esters of 2- ethyl hexanoic acid with different 2 groups of alcohols, the first one (1-hexanol, 2- ethyl hexanol,1-octanol, 1- dodecanol and 1- hexadecanol), and the second group (neopentyl glycol, trimethylol propane and pentaerythritol). All the preparation compound form were confirmed by examine the physical and chemical properties as (Nuclear Magnetic Resonance, Infra-Red Spectroscopy, Total Acid Number, Density, Thermo Gravimetric Analysis TGA, Specific gravity, Reflective index, Molecular weights estimation and flash point). As a synthetic lubricating oil, the performance of these compounds was studied. Prepared compounds have been found to contain low pour point (PP), high viscosity level (VI) and Newtonian fluid for rheological behavior.

USE OF ACID ANHYDRIDE ACCELERANTS FOR THE PRODUCTION OF HIGH PURITY POLYOL ESTERS

A method of producing high purity polyol esters comprises reacting a polyol with an excess amount of a linear or branched aliphatic monocarboxylic C3-20 acid to esterify less than the total amount of the polyol present to form an intermediate reaction composition having a hydroxyl value of from 7 to about 50 mg KOH/g. An anhydride of the corresponding linear or branched aliphatic monocarboxylic C3-20 acid is added to the intermediate reaction composition in an amount of from 1 to about 2.5 equivalents of available OH in the intermediate composition to form a reaction mixture. The reaction mixture is heated for 5-30 minutes or until all of the corresponding anhydride has reacted to form a reaction product. The reaction product is then de-acidified. No metal or acid catalyst or bleaching agents are present in any of the above reaction steps at a concentration above about 15 ppm.

ESTER COMPOUND

PROBLEM TO BE SOLVED: To provide a novel asymmetric polyol ester compound that can easily be synthesized under a mild reaction condition from a variety of carboxylic acids and carboxylic acid esters and that has a low melting point and is excellent in viscosity index, heat resistance and color number. SOLUTION: Provided are an ester compound represented by the following formula (1), and a lubricating-oil and cosmetic raw-material containing the same. In the formula, R1 and R6 are, each independently, an alkyl group, aralkyl group or aryl group having 1 to 20 carbon atoms. R2, R3, R4 and R5 are, each independently, an alkyl group having 1 to 10 carbon atoms, and the combination of R2 and R3 and the combination of R4 and R5 are different. COPYRIGHT: (C)2016,JPO&INPIT
