摘要： Fatty acids are made from corresponding carboxylate soaps by a method which comprises dissolving the soaps in at least one fatty acid in a melted state in the absence of oxygen, contacting the liquid solution of soap in fatty acid with an aqueous solution containing an amount of strong mineral acid at least stoichiometrically equivalent to the soap and allowing the cations of soap and strong acid to exchange phases, the amount of water being just sufficient to dissolve substantially all of the mineral salt thus formed.

摘要： A method of separation and recovery of neutral and lipid components contained in saponifiable mixtures such as lipids and residues of plant and animal origin or saponified such as Tall Oil Soap (TOS), or in their saponified derivatives, which is based on differences in their solubility in a solvent or in a mixture of solvents from the group consisting of water and alcohols.

摘要： Embodiments of the present invention provide a method, comprising obtaining a lecithin-containing material, in some aspects derived from a crude refining stream, comprising 20-80 wt % acetone insoluble matter, 1-30 wt % free fatty acid, and less than 10 wt % water, adding a fatty acid or carboxylic source to the lecithin-containing material to obtain a lecithin fatty acid blend or lecithin carboxylic acid blend and incorporating the blend into asphalt or oil field applications.

摘要： A process for production fatty acids comprising: adjusting pH of a saponifiable material to a value above pH 7 by adding alkaline material; saponifying all saponifiable material by passing alternate electrical current through the material, wherein the said step of saponification occurs in a saponification reactor; acidulating the saponified material by adding acid to pH value below 4; isolating obtained free fatty acids from aqueous layer.
