Abstract
There is disclosed an improved telomerized oil comprising no more than 4% polyunsaturated fatty acids and a plurality of aliphatic rings, wherein the improved telomerized oil is made from about 20% to about 70% of a conjugated triglyceride oil, wherein the conjugated triglyceride oil has at least 50% of fatty acids having at least two conjugated double bonds and from about 30% to about 80% of a vegetable triglyceride oil, wherein the vegetable triglyceride oil has from about 10% to about 75% of its fatty acids being polyunsaturated and having from about 16 to about 26 carbon atom chain length (unbranched). The present invention further provides an improved telomerized oil produced by a process comprising heating from about 20% to about 70% of a conjugated triglyceride oil, wherein the conjugated triglyceride oil has at least 50% of fatty acids polyunsaturated with at least two conjugated double bonds and from about 30% to about 80% of a vegetable triglyceride oil, wherein the vegetable triglyceride oil has from about 10% to about 75% of its fatty acids being polyunsaturated and having from about 16 to about 26 carbon atom chain length (unbranched), in a non-oxidizing atmosphere at from about 150.degree. C. to about 400.degree. C. for from about 3 hours to about 10 hours to lower the amount of polyunsaturation in the conjugated triglyceride oil and vegetable triglyceride oil to less 4% through the formation of aliphatic rings. The present invention further provides a process for synthesizing an improved telomerized oil, comprising heating from about 20% to about 70% of a conjugated triglyceride oil, wherein the conjugated triglyceride oil has at least 50% of fatty acids polyunsaturated with at least two conjugated double bonds and from about 30% to about 80% of a vegetable triglyceride oil, wherein the vegetable triglyceride oil has from about 10% to about 75% of its fatty acids being polyunsaturated and having from about 16 to about 26 carbon atom chain length (unbranched), in a non-oxidizing atmosphere at from about 150.degree. C. to about 400.degree. C. for from about 3 hours to about 10 hours to lower the amount of polyunsaturation in the conjugated triglyceride oil and vegetable triglyceride oil to less 4% through the formation of aliphatic rings.
