METHOD OF MANUFACTURING RENEWABLE DIESEL FROM BIOLOGICAL FEEDSTOCK
A method for producing renewable diesel includes introducing a primary feedstock comprising biologically-derived triglycerides with catalyst poisons into a first reaction chamber and hydrolyzing the primary feedstock within the first reaction and liquid-liquid extraction chamber for at least an hour such that the reacted triglycerides are separated into an aqueous solution comprising glycerol and catalyst poisons, and an intermediate feedstock comprising free fatty acids and catalyst poisons. The method also includes distilling the intermediate feedstock to separate the intermediate feedstock into a purified intermediate stream and a lower volume bottom stream containing unreacted triglyceride, diglyceride, monoglyceride, FFA and catalyst poisons. The method also includes combining the purified intermediate feedstock with a hydrogen stream and converting, in a second reaction chamber comprising a metallic catalyst bed, the purified intermediate feedstock into a product comprising long-chain alkanes. The method also includes hydrotreating the purified intermediate feedstock into a renewable diesel product.

Method for preparing 2-monoacylglycerides
Methods for preparing and purifying 2-monoacylglyceride compounds are disclosed. In one method, an unsaturated triglyceride is reacted with water, a C.sub.1-C.sub.8 alcohol, or a mixture thereof in the presence of a lipase to produce a mixture comprising a 1,3-dihydroxy-2-monoacylglyceride and fatty esters or acids. Reaction of the 1,3-dihydroxy-2-monoacylglyceride with an aldehyde or ketone gives a mixture comprising a 2-monoacylglyceride acetal or ketal. Fatty esters or acids are removed from the mixture as an overhead product by distillation or wiped-film evaporation to isolate a purified 2-monoacylglyceride acetal or ketal. The inventive methods provide a 2-monoacylglyceride protected at the 1- and 3-positions such that the acyl unit remains at the 2-position. The products are enriched in unsaturated fatty acid content when compared with the unsaturated fatty acid content of the original unsaturated triglyceride. Each method utilizes a practical purification scheme that avoids the scale-up or toxicity issues of commonly employed purification strategies.
FLEXIBLE WAX AND METHOD OF MAKING SAME
The disclosure relates to flexible wax compositions and a method of making the same. Described herein is a wax composition containing about 20 wt % to about 45 wt % monoacylglycerides, about 28 wt % to about 40 wt % diacylglycerides, and about 10 wt % to about 45 wt % acylglyceride polymers, which contain one or more dimerized fatty acid residue and a plurality of glycerol moieties. The flexible wax composition described herein has an average creep stiffness of less than about 30 MPa and can be used in candles, paper coatings, box coatings, fruit coatings, broadsizing for OSB, tire and rubber, polyvinyl chloride piping, crayons, and personal care applications.
