Abstract
Methods to convert biobased oils, oil derivatives, and modified oils to highly functionalized esters, ester polyols, amides, and amide polyols. The products can be used to make polyurethane and polyester films and foams.
Claims20
A method for producing amides comprising:
- A. amidifying a biobased oil, or oil derivative so that substantially all of the fatty acids are amidified at the fatty acid glyceride sites;
- B. reacting the amidified biobased oil, or oil derivative with ozone and excess alcohol in the presence of a solvent at a temperature between about −80° C. to about 80° C. to produce intermediate products;
- C. refluxing the intermediate products or reacting the intermediate products at lower than reflux temperature, wherein ester alcohols are produced from the intermediate products at double bond sites to produce a hybrid ester/amide.
