Implementations of wax ester compositions may include: a product of transesterifying oleyl oleate, stearyl stearate, and behenyl behenate using one of a chemical or an enzyme catalyst. The ratio of the oleyl oleate to stearyl stearate to behenyl behenate in the mixture prior to transesterification is one of 65%/23%/12%, 56%/29%/15%, or 36%/34%/30%, respectively, measured by weight. The product may demonstrate a substantially equivalent physical property to a physical property of a transesterified wax ester composition including a jojoba ester.

The use of hypophosphorous acid as a corrosion inhibitor for esterification reactions of free fatty acids contained in a fatty substance is described, particularly in the presence of an organosulfonic acid. The invention also relates to a method for the esterification of fatty acids.

According to one or more embodiments of the present disclosure, a method for producing an emulsifier suitable for use in an emulsion drilling fluid may comprise esterifying a processed vegetable oil to produce a first mixture comprising fatty acid alkyl esters. The processed vegetable oil may comprise less than 1 wt. % of compounds having an atmospheric boiling point less than or equal to 150° C. The method may further comprise removing at least 99 wt. % of each of glycerol, water, and short-chain alcohols having a main chain of less than or equal to 12 carbon atoms from the first mixture to produce a modified mixture, and hydrolyzing the fatty acid alkyl esters of the modified mixture with a base to produce the emulsifier comprising at least one salt of a fatty acid. Emulsion drilling fluids comprising the emulsifier and methods of producing emulsion drilling fluids are also disclosed.

The present disclosure provides compounds useful as ionizable cationic lipids. The ionizable cationic lipids are useful for preparing lipid nanoparticles for the delivery of therapeutic nucleic acids to cells. Cationic ionizable lipids were engineered with improved stability to oxidative degradation while in storage.

This disclosure provides methods for the chemical modification of triglycerides that are highly enriched in specific fatty acids and subsequent use thereof for producing functionally versatile polymers.

Provided is a system and method for producing and purifying biodiesel. In particular, the system comprises a tandem arrangement of at a modular biodiesel reactor and a continuous flow separation and purification unit. The system can further comprise an evaporation unit that is placed between the biodiesel reactor and the continuous flow separation and purification unit.

An improved biodiesel production process includes the steps of processing a feedstock to produce biodiesel, cooling the biodiesel so as to form sediment, and filtering the biodiesel to remove the sediment. The resulting biodiesel from the cold filtration process avoids problems of sediment formation during storage and transportation.

The present application relates to methods of producing one or more fatty alcohols and/or one or more fatty aldehydes from one or more unsaturated lipid moieties by combining the obtainment or production of the one or more unsaturated lipid moieties from a biological source with conversion by non-biological means of the one or more unsaturated lipid moieties to one or more fatty alcohols and/or one or more fatty aldehydes. The present application also relates to recombinant microorganisms having a biosynthesis pathway for the production of one or more unsaturated lipid moieties. The one or more fatty alcohols can further be chemically converted to one or more corresponding fatty acetates. The one or more fatty alcohols, one or more fatty aldehydes and/or one or more fatty acetates produced by the methods described herein may be one or more insect pheromones, one or more fragrances, one or more flavoring agents, or one or more polymer intermediates.

A transesterification catalyst that is heterogeneous and a method for preparing said transesterification catalyst are provided. The catalyst can be used in a variety of transesterification reactor configurations including CSTR (continuous stirred tank reactors), ebullated (or ebullating) beds or any other fluidized bed reactors, and PFR (plug flow, fixed bed reactors). The catalyst can be used for manufacturing commercial grade biodiesel, biolubricants and glycerin.
