The disclosure generally provides branched diester compounds having exceptional low-temperature and flow properties. The disclosure also provides uses of the branched diester compounds in lubricant compositions, for example, as a base oil, and in other applications where their low-temperature and flow properties can be employed beneficially. The disclosure also provides efficient and green methods for making the branched diester compounds. In certain embodiments, a vegetable oil-based diester (1,6-hexyldioleate) was branched with propanoic acid (C3) using a green synthetic approach involving solvent-free and catalyst-free epoxide ring opening followed by in situ normal esterification. A total of three branched ester derivatives possessing varied numbers of internal protruding branched ester groups and hydroxyl groups were obtained. All of the pure branched derivatives were comprised of mixtures of positional isomers and/or stereoisomers. Differential scanning calorimetry (DSC) showed that regardless of the composition inhomogeneity of each branched derivative, crystallization was suppressed completely in all of the branched compounds, and they all demonstrated glass transitions below −65° C. Without being bound by any theory, it is believed that this unique thermal behavior is attributed to the internal protruding branched moieties and hydroxyl groups, which dramatically slowed down mass transfer starting with the least branched compound (2-branched derivative). The viscosity of the branched compounds was one order of magnitude larger than that of the starting di ester due to the increased branching and increased resistance to flow associated with hydrogen bonding introduced by the OH groups. Overall, these branched diesters demonstrated superior low temperature and flow properties comparable to existing non-sustainable commercial lubricants and analogous biobased materials which makes them suitable alternatives for use in lubricant formulations particularly in high ...

Process for integrated production of renewable fuels and chemicals

The present disclosure provides a versatile process for producing valuable renewable hydrocarbons from triglyceride containing feedstock. In the stepwise process, the triglyceride containing feedstock is first split to provide a mixture comprising fatty acids, glycerol and water, from which a phase separation provides an oily phase, and an aqueous phase. Said oily phase comprising fatty acids is subjected to fractionation. Fractionation divides the fatty acids to specific fractions, which may be refined to products with controlled hydroprocessing. Products may comprise paraffinic renewable aviation fuel components, paraffinic renewable base oil, renewable paraffinic diesel fuel components, renewable paraffinic technical fluid, or any combination thereof.

Paraffinic products, a method for producing paraffinic products and a use of paraffinic products

An electrotechnical fluid composition, comprising more than 90 wt-% paraffins in the C17- C18 range, based on the total weight of the composition, is described. The ratio of the amount of C18 i-paraffins to the amount of C18 n- paraffins is more than 40, based on the weight of the C18 i-paraffins and the weight of the C18 n-paraffins in the composition.

Renewable base oil production engaging metathesis

Herein is provided a process for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process comprises subjecting a feedstock comprising free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. The ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of said metathesis product comprises recovery of a fraction comprising or consisting essentially of C16 fatty acid esters, which is subjected to ketonisation reaction conditions to produce long chain ketones, which after hydrotreatment meet requirements for a renewable base oil. Ketonisation reaction produces renewable alkene usable in metathesis reaction.

Renewable alkene production engaging metathesis

Herein is provided a process for producing renewable products, such as alkenes, from a feedstock of biological origin. The process comprises subjecting a feedstock comprising fatty acid glycerides and optionally free fatty acids, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. The ester stream thereby obtained is then fractionated and a fraction comprising esters of unsaturated C18 fatty acids is subjected to metathesis conditions in the presence of an alkene to obtain metathesis products. Fractionation of said metathesis products comprises recovery of at least renewable 1-decene, and unsaturated C10-C15 fatty acid esters.
