Disclosed is a process for production of a final vegetable oil composition having at least 50% palmitic acid present in the sn2-position out of total palmitic acid in the triglycerides of the final vegetable oil composition, wherein the process comprises a step of providing a starting vegetable oil composition comprising palmitic acid in the triglycerides, a step of performing an enzymatic transesterification process, and a step of using excess free fatty acids and/or non-glyceride esters thereof obtained during the process and recycling them back into the process; wherein at least 70% by weight out of the total amount of palmitic acid in the starting vegetable oil composition is present in the final vegetable oil composition. A vegetable oil composition obtained by the disclosed process, use of said vegetable oil composition in the manufacture of an infant formula, and an infant formula comprising the vegetable oil composition is further disclosed.

Disclosed are petrolatum-like compositions that include metathesized unsaturated polyol esters. Also disclosed are emulsions that include metathesized unsaturated polyol esters. The petrolatum-like compositions may be used as substitutes for petroleum-based petrolatum. The emulsions may be water-in-oil or oil-in-water emulsions and may be suitable for a variety of end uses.
摘要:
A system and method for the conversion of free fatty acids to glycerides and the subsequent conversion of glycerides to glycerin and biodiesel includes the transesterification of a glyceride stream with an alcohol. The fatty acid alkyl esters are separated from the glycerin to produce a first liquid phase containing a fatty acid alkyl ester rich (concentrated) stream and a second liquid phase containing a glycerin rich (concentrated) stream. The fatty acid alkyl ester rich stream is then subjected to distillation, preferably reactive distillation, wherein the stream undergoes both physical separation and chemical reaction. The fatty acid alkyl ester rich stream is then purified to produce a purified biodiesel product and a glyceride rich residue stream. The glycerin rich second liquid phase stream may further be purified to produce a purified glycerin product and a (second) wet alcohol stream. Neutralization of the alkaline stream, formed during the alkali-catalyzed transesterification process, may proceed by the addition of a mineral or an organic acid.
摘要:
The present invention provides a method for producing a refined fatty acid alkyl ester (FAAE) product from feed-stocks containing free fatty acids. The method comprises glycerolysis and transesterification processes combined with end-product refining. Products produced from a transesterification reaction are separated into a crude FAAE stream and a crude glycerin stream. The crude glycerin stream is further processed to produce a glyceride stream from which additional FAAEs may be produced.
摘要:
A method is disclosed for the preparation of glycerol esters (triglycerides) of medium-chain length monocarboxylic fatty acids which consists of the reaction of the precursor free fatty acid and glycerol in the presence of a catalyst under partial vacuum. The process preferably uses a metal catalyst such as an oxide or a chloride of tungsten, molybdenum, calcium, zinc, chromium or magnesium. The method of the invention allows the preparation in high yield and high purity (>99.5%) of the final triglyceride. The present method allows the formation of triglycerides without solvent. Are also contemplated, the triglyceride obtained by the method, and the pharmaceutical composition containing the triglyceride as an excipient or as an active ingredient.
摘要:
The disclosed apparatus, systems and methods relate to the conversion of high free fatty acid (“HFFA”) containing oils defined as oils containing 20-100% free fatty acids (“FFA”) and low free fatty acid (“LFFA”) containing oils defined as oils containing 1-20% free fatty acids (FFA) into oil with less than about 0.5-1% FFA. If the feedstock is HFFA oil, the process includes a combination of partial glycerolysis of HFFA oils to produce LFFA oils and subsequent stripping of LFFA oils to produce NFFA oils via steam distillation. If the feedstock is LFFA oil, the process includes stripping of LFFA oils to produce NFFA oils via steam distillation and subjecting FFA to partial glycerolysis to convert FFA to oil.
摘要:
A method for producing an ester polyol, comprising transesterifying a first ester polyol with a primary polyol to produce a second ester polyol, wherein the second ester polyol has a higher hydroxyl value than the first ester polyol.
摘要:
The invention discloses an improved process for preparing fatty acid esters with 100 mol % selectivity suitable as biodegradable lubricant base oils, comprising contacting a fatty compound with an alcohol in presence of a solid, phosphonate catalyst having molecular formula: M(X)2-nYn.mH2O where X refers to phenyl phosphonate, Y refers to HPO42− or HPO32−, M refers to a metal or metalloid ion preferably taken from the group consisting of Zr, Zn, Cd, Al, Sn, La and Ce, the value of n varies from 0.2 to 1.8 and the value of m varies from 0 to 5, wherein the fatty compound is a fatty acid or fatty acid methyl or ethyl ester or vegetable oil or animal fat or their mixture thereof and alcohol is a monohydric alcohol with 6 to 22 carbon atoms or a polyol with at least two hydroxyl groups.
