LYMPHATIC SYSTEM-DIRECTING LIPID PRODRUGS

The present invention provides lymphatic system-directing lipid prodrugs, pharmaceutical compositions thereof, methods of producing such prodrugs and compositions, as well as methods of improving the bioavailability or other properties of a therapeutic agent that comprises part of the lipid prodrug. The present invention also provides methods of treating a disease, disorder, or condition such as those disclosed herein, comprising administering to a patient in need thereof a provided lipid prodrug or a pharmaceutical composition thereof.

MIXED OXIDE COMPOSITE COMPRISING CALCIUM OXIDE AND TRICALCIUM ALUMINATE

The invention relates to a composite oxide comprising CaO stabilised by Ca.sub.3Al.sub.2O.sub.6 (C3A), wherein the composite is in the form of particles. The mixed oxide composite is useful as a catalyst in the transesterification of triglycerides, e.g. in the production of biodiesel. Calcium leaching is more hindered in CaO—Ca.sub.3Al.sub.2O.sub.6 (2Ca/Al) than in CaO—Al.sub.2O.sub.3.

Production of insect pheromone precursors in plants

Wax esters (WE) and triacylglycerols (TAG) can be accumulated in large amounts in plant cells. The present invention relates to insect pheromone precursors which are produced as components of WE or TAG in plants. Further the invention concerns means and methods for the production of plant cells producing WE and/or TAG containing insect pheromone precursors in form of either a fatty acid or a fatty alcohol. Said method uses plants where wax esters are modified by desaturase, fatty acyl reductase and wax ester synthase or the triacylglycerol is modified by a desaturase. Finally the insect pheromone precursors can be extracted and used in the manufacturing of insect pheromones from WE and TAG.

Renewable base oil production engaging metathesis
11643616 · 2023-05-09 · ·

A process is disclosed for producing renewable products, such as a renewable base oil, from a feedstock of biological origin. The process includes subjecting a feedstock containing free fatty acids and fatty acid glycerides, wherein at least one hydrocarbon chain is unsaturated, to esterification reaction in the presence of an alcohol. An ester stream thereby obtained is then subjected to metathesis conditions in the presence of a renewable alkene to obtain a metathesis product. Separation of the metathesis product includes recovery of a fraction containing 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.

Process for producing alkyl methacrylates with improved water and acid management

A process for producing alkyl methacrylates, in particular methyl methacrylate (MMA), includes production of methacrolein (MAL) in a first reaction stage; direct oxidative esterification (DOE) of the methacrolein with an alcohol, preferably methanol, to afford an alkyl methacrylate in a second reaction stage; and workup of the alkyl methacrylate crude product from the second reaction stage. An optimized workup of the reactor output from the oxidative esterification of methacrolein involves minimizing the amount of employed water, the amount of employed acid, and/or the amount of aqueous waste streams, through an optimized recycling of the generated process water streams.

METHOD OF MANUFACTURING BIO-DIESEL AND REACTOR

A reactor and process for the production of bio-diesel. The reactor includes one or more coiled reaction lines. The lines are positioned within a tank containing a heat transfer media such as molten salt, maintained at about 750° F. A pump circulates the media within the tank. An emulsion of alcohol; refined feed stock, including glycerides and/or fatty acids; and preferably water is pumped through the reaction lines at temperatures and pressures sufficient to maintain the alcohol in a super-critical state. The curvature of the coils, pump pulsing, and the flow rate of the emulsion keep the emulsion in a turbulent state while in the reactor, ensuring thorough mixing of the alcohol and feed stock. The alcohol reacts with the glycerides and fatty acids to form bio-diesel. The reaction is fast, efficient with regard to energy input and waste generation, and requires minimal alcohol.
