Skeletal isomerization of alkyl esters and derivatives prepared therefrom

The present invention relates to a process for the skeletal isomerization of unsaturated linear fatty acids to branched fatty acids which comprises contacting said unsaturated linear fatty acids with at least one large pore zeolite catalyst wherein said at least one zeolite catalyst comprises a material having a three dimensional channel structure having a pore diameter of at least 6.0 Å. In another embodiment, the invention relates to a process for the skeletal isomerization and hydrogenation of unsaturated linear fatty acids to saturated branched fatty acids which comprises contacting said unsaturated linear fatty acids in the presence of an acidic catalyst, wherein said acidic catalyst comprises a mesoporous crystalline phase having pore walls containing primary and secondary crystalline building unit structures.

Method of dry fractionation of fat or oil

It is intended to provide a procedure for, in the fractionation of vegetable butter, transesterified fat or oil, isomerized hydrogenated fat or oil, etc. without the use of solvents, obtaining high-concentration component G2U (defined below) by concentrating operation through reduction of the amount of liquid component residue in crystal portion. There is provided a method of dry fractionation of fat or oil characterized in that fat or oil (A) containing components G2U and GU2 is fractionated through crystallization / solid-liquid separation into crystal fraction of concentrated G2U (AF) and liquid fraction of concentrated GU2 (AL), subsequently this crystal fraction (AF) is mixed with liquid G2U-containing fat or oil (B) whose GU2 concentration is lower than that of the liquid fraction (AL) and thereafter the mixture is separated into crystal fraction (BF) and liquid fraction (BL). Provided that G represents a saturated or trans acid form fatty acid residue; U a cis form unsaturated fatty acid residue; and G2U a triglyceride of G2-residue and U1-residue bonded together.

Method for preparing biological lubricating oil base oil by using epoxy biodiesel

The invention aims at solving the defects of long reaction time and high reaction temperature of a heterogeneous etherification ring-opening reaction of epoxy biodiesel of prior arts, and provides a method for preparing biological lubricating oil base oil by using epoxy biodiesel. The method comprises the steps that: (1) under a condition of ultrasonic-assisted heat and mass transfer, the heterogeneous etherification ring-opening reaction is carried out, wherein long-chain fatty alcohol and a metal-ion-load-type cation exchange resin solid catalyst are mixed and heated to a reaction temperature; epoxy biodiesel is added for carrying out the ring-opening reaction; when an epoxy value is smaller than 0.1, the reaction is stopped; the reaction mixture is cooled to room temperature, and is washed by using distilled water; a lower-layer aqueous phase and the solid catalyst are separated, and the solid catalyst is recovered; an upper-layer organic phase is washed to neutral; and vacuum dehydration and light component removing are carried out, such that isomerized fatty alcohol ether is obtained; and (2) the product obtained in the step (1) is subjected to clay discoloration, such that clear and transparent biological lubricating oil base oil is obtained. According to the adopted catalyst, the catalytic active agent has high selectivity.

Preparation and application of polyunsaturated fatty acid containing rich conjugated linoleic acid

The invention discloses preparation and application of polyunsaturated fatty acid containing rich conjugated linoleic acid and belongs to the technical field of polyunsaturated fatty acid extraction and steady-state treatment of grease. A preparation method comprises the following steps: (1) preparing mixed fatty acid by utilizing an enzymolysis method; (2) enriching the polyunsaturated fatty acid by utilizing a urea-inclusion method; (3) enriching the conjugated linoleic acid by combining a super-critical CO2 extraction method and an alkali isomerization method to finally obtain the polyunsaturated fatty acid containing the rich conjugated linoleic acid, wherein the content of the conjugated linoleic acid reaches 90 percent or more and a product contains other polyunsaturated fatty acid at the same time so that the structure of the product is more reasonable. By adopting a method for preparing microcapsules or emulsion, the polyunsaturated fatty acid containing the rich conjugated linoleic acid is subjected to stabilization treatment, so that the storage stability of the product is improved and the storage period can reach 24 months; meanwhile, the bioavailability of the polyunsaturated fatty acid is improved and the polyunsaturated fatty acid is more easily digested and absorbed by human bodies.

Isolation and subsequent utilization of saturated fatty acids and α-olefins in the production of ester-based biolubricants

The present invention is generally directed to the synthesis and / or manufacture of ester-based lubricant compositions. The present invention is also directed to methods of making these and other similar lubricant compositions, and to systems for implementing such methods (processes). In some embodiments, the methods for making such ester-based lubricants utilize a biomass precursor (e.g., triglyceride-bearing vegetable oils) such that the lubricant compositions generated by the methods and systems of the present invention can be properly deemed biolubricants. In these or other embodiments, lubricant precursor species can also be sourced or derived from Fischer-Tropsch (FT) and / or long-chain paraffin pyrolysis reaction products. The ester component of the lubricant compositions, produced in accordance with the methods and systems of the present invention, comprises largely diester species.
