Abstract
A bio-organic composition includes residues of a fatty acid glyceride-containing composition, residues of a first epoxide or glycol, and the residues of a second epoxide. The fatty acid glyceride-containing composition is characterized by the viscosity at room temperature. The first epoxide or glycol and second epoxides are present in a sufficient amount that the room temperature viscosity of the bio-organic composition is lower than the room temperature viscosity of the vegetable oil prior to formulation and/or the first epoxide or glycol and second epoxides are present in a sufficient amount that the pour point of the bio-organic composition is lower than the pour point of the fatty acid glyceride-containing composition prior to formulation.
Claims17
A method of forming a bio-organic composition, the method comprising:
- a) mixing a fatty acid glyceride-containing composition and a first reaction promoter at a first predetermined temperature to form a first intermediate reaction mixture, the first predetermined temperature being from 200° F. to 350° F.;
- b) adding a first epoxide or glycol to the first intermediate reaction mixture to form a second intermediate reaction mixture;
- c) combining at least a portion of the second intermediate reaction mixture with water and additional reaction promoter to form a third intermediate reaction mixture, the water partially hydrolyzing fatty acid glycerides in the fatty acid glyceride-containing composition such that the bio-organic composition includes less than 5 weight percent free glycerol;
- d) adding a second epoxide to the third intermediate reaction mixture to form a fourth intermediate reaction mixture;
- and
- e) removing the water under a vacuum such that the bio-organic composition is recovered, the bio-organic composition including glycerol esterified with one or two acid groups and free glycerol in an amount that is less than 5 weight percent.
A bio-organic composition comprising:
- residues of a fatty acid glyceride-containing composition, the fatty acid glyceride-containing composition having a first viscosity and a first pour point, the residues of the fatty acid glyceride-containing composition including glycerol being esterified with one or two acid groups from an initial fatty acid glyceride-containing composition;
- residues of a first epoxide present in a first epoxide concentration or residues of a first glycol present in a first glycol concentration;
- residues of a second epoxide present in a second epoxide concentration, wherein the first epoxide is the same or different than the second epoxide;
- glycerol esterified with one or two acid groups;
- and
- free glycerol in an amount that is less than 5 weight percent wherein the bio-organic composition has a viscosity lower that the first viscosity and/or a pour point lower than the first pour point.
