Solventless esterification of fatty acids with trimethylolpropane using sulfonated amorphous carbons derived from wood powder

Polyolesters synthesized by an esterification between polyols and fatty acids are value-added oleochemicals widely used as lubricants, cosmetics, and food additives among other applications. However, homogeneous acid catalysts are still preferred in their industrial production, despite their associated energy cost and the environmental issues that they present. In this paper, we describe lignocellulose-derived amorphous carbons with a high loading level of SO3H and their application to the synthesis of polyolesters as a biobased heterogeneous acid catalyst. These sulfonated amorphous carbons could be readily prepared via (i) heat treatment at 400?°C for 1?h and (ii) sulfonation with chlorosulfuric acid. XRD and BET analyses demonstrated that these carbonaceous materials were not crystalline but were amorphous structures with a low surface area. The attachment of SO3H groups was confirmed by FT-IR and XPS, and the loading level of SO3H was determined by CHNS elemental analysis. Chlorosulfuric acid gave a higher loading level of SO3H than other sulfating agents, such as conc. sulfuric acid and fuming sulfuric acid. The higher SO3H-loaded amorphous carbons exhibited a greater catalytic activity for esterification between trimethylolpropane and fatty acids under solventless conditions. Esterification of oleic acid derived from vegetable oil with trimethylolpropane using this catalyst afforded the desired biolubricant at over 93% yield in 3?h. The sulfonated amorphous carbons could be reused three times without any significant loss of catalytic activity.

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.

METHOD FOR PREPARING ESTER COMPOUND USING SULFONIC ACID OR SULFONATE CATALYSTS

The present invention provides a manufacturing method of an ester compound, which obtains an ester compound by using any one of sulfonic acid and sulfonate as a catalyst and performing an esterification reaction of polyhydric alcohol and fatty acid. Accordingly, the method has excellent activities in comparison with the existing acid catalyst, thereby efficiently manufacturing a polyhydric fatty acid ester compound during rapid reaction time even with a small amount. In addition, the method has the advantages of easily filtering a perfluorosulfonic acid catalyst from a reaction mixture after an ester reaction, and reusing the same by drying.(AA) CF3SO3H(9mg) example 1(BB) CF3SO3H(3mg) example 3(CC) CF3SO3H(12mg) example 5(DD) Nafion NR-50(25mg) example 7(EE) Twice-reused nafion NR-50(25mg) example 9(FF) Not using comparative example 1(GG) CF3SO3H(18mg) example 2(HH) CF3SO3H(18mg) example 2(II) CF3SO3H(2mg) example 6(JJ) Once-reused nafion NR-50(25mg) example 8(KK) Nafion-Sc(25mg) example 10(LL) PTSA(3.8mg) comparative example 2(MM) Triester production rate(%)(NN) TimeCOPYRIGHT KIPO 2016
