Disclosed herein, inter alia, are fatty acid and polymer compositions and methods of making the same.

A method for producing an EPA alkyl ester-containing composition includes: preparing a raw material oil containing an EPA alkyl ester in an amount of from 50 to 92% by mass in the total fatty acids, in which a mass ratio of a DHA alkyl ester to the EPA alkyl ester contained in the raw material oil is 3.3% by mass or less and further a ratio of trans isomers in the EPA alkyl ester contained in the raw material oil is 2% by mass or less; bringing the raw material oil into contact with an aqueous solution containing a silver salt; recovering the aqueous solution containing the silver salt brought into contact with the raw material oil; bringing the recovered aqueous solution containing the silver salt into contact with an organic solvent; and recovering the organic solvent brought into contact with the aqueous solution containing the silver salt.

Present invention relates to a novel process for purification of lipid material for further use as such as e.g. a source of fuel or chemicals.

Disclosed is a method for extracting one or more chemical extracts from a plant product. The chemical extracts are purified and extracted by first separating at least a phytochemical bearing part of a plant product from one or more other portions of the plant product. A carrier oil is then heated at a target temperature to be used as the vehicle for extraction and then mixed with the at least a phytochemical bearing part while the target temperature is maintained. The process may be streamlined by having heating and mixing occur in a press device. The mixed carrier oil and the at least a phytochemical bearing part are then passed through the press device to produce an oil mixture. At least a chemical extract may be extracted from the oil mixture, and in some cases may be further purified by evaporation and/or centrifugation.

A process for producing flavorants made or derived from tobacco or, more generally, made or derived from any biomass derived from any one or more species of genus Nicotiana, or that otherwise incorporate tobacco, is provided. Provided are flavorants obtained or derived from plants or portions of plants from the Nicotiana species, such as from one or more flowers from one or more Nicotiana species, and products comprising one or more such flavorants.

The present disclosure provides an efficient process for separating components of tall oil fatty acids (TOFA) and for purifying TOFA from rosin. The process includes mixing TOFA with a novel solvent system containing urea to form urea clathrates, resulting in separation of saturated fatty acids from unsaturated ones and rosin from TOFA by utilizing proper urea to TOFA ratio.

The invention provides methods that can be used to separate mixtures of fatty acids and fatty acid esters into individual components or into more concentrated mixtures of individual components.

The present invention is related to a method for purifying crude -sulfo fatty acid salt obtained by the reaction of fatty acid and sulfur oxides, comprising the following steps: a) diluting the crude -sulfo fatty acid in a solvent and adjusting the ph from 2 to 4; b) heating up the slurry of a-sulfo fatty acid salt obtained in the step a) until being fully solubilized: c) cooling down the solution of -sulfo fatty acid salt obtained in the step b) to room temperature gradually to obtain the crystals; d) filtering the crystal obtained in the step c) to remove the motherinsing the filter cake at least twice with acid aqueous solution to obtain the purified -sulfo fatty acid salt.
