Abstract
Official abstract text for this publication.
Disclosed herein are processes for the decarboxylation, isomerization, hydrogenation, dehydrogenation, and cyclization/aromatization of fatty acids involving contacting a starting material which is an unsaturated fatty acid, unsaturated fatty acid derivative, or an unsaturated triglyceride, in the presence of a catalyst at a temperature at which decarboxylation, isomerization, hydrogenation, dehydrogenation, and cyclization/aromatization occurs and recovering the unsaturated organic compound product; wherein the catalyst is chloro-1,5-cyclooctadiene iridium (I) dimer. The product may contain at least about 8% by volume aromatic content and less than about 25% by volume aromatic content, and wherein the product contains less than about 1% by volume of naphthalenes.
First claim
Opening claim text (preview).
We claim: 1. A process for the decarboxylation, isomerization, hydrogenation, dehydrogenation, and cyclization/aromatization of fatty acids, said process comprising contacting a starting material which is an unsaturated fatty acid, unsaturated fatty acid derivative, or an unsaturated triglyceride, in the presence of a catalyst at a temperature at which decarboxylation, isomerization, hydrogenation, dehydrogenation, and cyclization/aromatization occurs and recovering the unsaturated organic compound product; wherein said catalyst is chloro-1,5-cyclooctadiene iridium (I) dimer. 2. The process according to claim 1 , wherein said product contains at least about 8% by volume aromatic content and less than about 25% by volume aromatic content, and wherein said product contains less than about 1% by volume of naphthalenes. 3. The process according to claim 1 , wherein said product contains at least about 8% by volume aromatic content and less than about 25% by volume aromatic content, and wherein said product contains less than about 0.1% by volume of naphthalenes. 4. The process according to claim 1 , wherein said starting material is a mixture of fatty acids. 5. The process according to claim 1 , wherein said starting material is soybean oil based fatty acids. 6. The process according to claim 1 , wherein said starting material is at least about 80% oleic soybean oil based fatty acids. 7. The process according to claim 1 , wherein said catalyst is chloro-1,5-cyclooctadiene iridium (I) dimer and at least one Ru catalyst.
