Abstract
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.
Claims20
A method comprising:
- providing a starting liquid that comprises two or more compounds selected from the group consisting of fatty acids and fatty acid esters, wherein each compound is present in a starting mole ratio with respect to each other compound;
- passing the liquid through a membrane that comprises covalent organic frameworks to provide a filtered liquid;
- and
- collecting a fraction of the filtered liquid wherein at least one mole ratio between two compounds has changed from the corresponding mole ratio in the starting liquid.
1 more element
A method for increasing the purity of a fatty acid or a fatty acid ester, from a starting liquid that comprises the fatty acid or the fatty acid ester and at least one other fatty acid or at least one other fatty acid ester, comprising:
- passing the starting liquid through a membrane that comprises covalent organic frameworks under conditions that allow the fatty acid or the fatty acid ester and the at least one other fatty acid or the at least one other fatty acid ester to pass through the membrane at different rates, so that the purity of the fatty acid or the fatty acid ester is increased on one side of the membrane.
