RENEWABLE FATTY ACID WAXES AND METHODS OF MAKING

摘要

Natural oil based fatty acid wax compositions and their methods of making are provided. The methods comprise providing a natural oil and hydrogenating and metathesizing the natural oil and then converting the hydrogenated metathesized natural oil to obtain a fatty acid wax comprising free fatty acids and/or salts of fatty acids glycerol and/or alcohol and paraffin wherein the fatty acid wax has at least 50 wt% of carbon chain compositions with at least 18 carbon atoms. The compositions may comprise 85 100 wt% long chain fatty acids 0 15 wt% esters wherein the fatty acid comprises between 15 60 wt% long chain di acids and 40 85 wt% long chain mono acids. The compositions may comprise about 50 100 wt% long chain fatty acids and about 0 50 wt% esters wherein the fatty acid may comprise between about 15 80 wt% long chain di acids and about 20 85 wt% long chain monoacids.
