摘要： Disclosed is a method for preparing a 1,3-dicarbonyl compound based on a metal hydride/palladium compound system. The method includes the following steps: suspending a palladium compound and a metal hydride in a solvent under the protection of nitrogen, then adding an electron-deficient olefin compound, reacting same at 0° C.-100° C. for 0.3 to 10 hours, then adding a saturated ammonium chloride aqueous solution to stop the reaction, and then subjecting same to extraction, evaporation until dryness, and column chromatography purification to obtain the 1,3-dicarbonyl compound. The hydride and palladium compound catalysts used by the present invention are reagents easily obtained in a laboratory. Compared to a common hydrogen hydrogenation method, the method is easier to operate, and has a higher safety, mild conditions, and a high reaction yield.

摘要： Methods are disclosed for producing renewable base oil and a diesel oil from low-value biological oils. Low-value biological oils containing free fatty acids and fatty acid esters can be processed into a renewable base oil and a renewable diesel oil by first separating at least part of the saturated free fatty acids from the feedstock and then processing separately this saturated free acid feed in a ketonisation reaction followed by hydrodeoxygenation and hydroisomerisation reactions to yield a renewable base oil stream. The remaining free fatty acid depleted feed may be processed in a separate hydrodeoxygenation and hydroisomerisation step to yield a renewable diesel stream.

摘要： A number of different branched hydrocarbon compounds (formula I) having a star-like configuration (S) are prepared from renewable oils containing fatty acids or derivatives containing fatty acids. The branched hydrocarbon compounds may be isolated individually or in mixtures, and may be used as part of base oils, such as renewable base oils (RBOs). A process for preparing the branched hydrocarbon compounds of formula I involve conditions that favour a trimerisation reaction followed by hydrotreating conditions. The compounds of formula I may be made by catalytically treating renewable material in a process, and the compounds have desirable qualities relating to lubrication, cold flow as well as having a low Noack volatility.

摘要： In one aspect, the invention provides a method for synthesizing a fatty olefin derivative. The method includes: a) contacting an olefin according to Formula I with a metathesis reaction partner according to Formula IIb in the presence of a metathesis catalyst under conditions sufficient to form a metathesis product according to Formula IIIb: and b) converting the metathesis product to the fatty olefin derivative. Each R1 is independently selected from H, C1-18 alkyl, and C2-18 alkenyl; R2b is C1-8 alkyl; subscript y is an integer ranging from 0 to 17; and subscript z is an integer ranging from 0 to 17. In certain embodiments, the metathesis catalyst is a tungsten catalyst or a molybdenum catalyst. In various embodiments, the fatty olefin derivative is a pheromone. Pheromone compositions and methods of using them are also described.

摘要： A method for producing a renewable base oil from a feedstock of biological origin includes providing a feedstock, the feedstock including: 2-95 wt % of a mixture of free fatty acids; 5-98 wt % fatty acid glycerols selected from mono-glycerides, di-glycerides and tri-glycerides of fatty acids; 0-50 wt % of one or more compounds selected from the list consisting of: fatty acid esters of the non-glycerol type, fatty amides and fatty alcohols; a major part of the feedstock being a mixture of free fatty acids and fatty acid glycerols; subjecting all or part of the feedstock to ketonisation reaction conditions where two free fatty acids react to yield a ketone stream, and subjecting the ketone stream to both hydrodeoxygenation and to hydroisomerisation reaction conditions, to yield a deoxygenated and isomerised base oil product stream containing the renewable base oil.
