Abstract
Methods of generating a surfactant composition from natural oil and utilizing greenhouse gas in its manufacture are described. The methods involve the reaction of a lipophilic cyclic carbonate functionalized material with a functionalized amine to form the surfactant. The surfactant has a significant level of biobased carbon content and utilizes either petroleum-derived, biobased, or fermentation-derived greenhouse gas in its manufacture.
Claims36
A method of making a surfactant comprising a hydroxy urethane linkage comprising:
- reacting a lipophilic cyclic carbonate functionalized material with a functionalized amine to form the surfactant;
- wherein the lipophilic cyclic carbonate functionalized material is derived from a plant or animal oil, a fatty acid, a fatty acid ester, a fatty acid amide, or combinations thereof;
- wherein the functionalized amine comprises an amine having a first functional group which forms the hydroxy urethane linkage and a second functional group having hydrophilic functionality.
A surfactant having a formula:
- wherein R1, R2, and R3 are independently polar groups comprising a hydroxyl, an amine, an acid, or mixtures thereof;
- wherein n is an integer from 0 to 3, and m is 9-3n or when the acid is stearic or palmitic acid, m is 9 or 6, wherein the tertiary screen is at a bottom of the burn zone or in the reheat zone.
A surfactant having a formula
- wherein R1 are independently is a polar groups comprising a hydroxyl, an amine, an acid, or a mixtures thereof;
- wherein n is typically an integer from 0 to 3.
A surfactant having a formula
- wherein R1 are independently is a polar groups comprising a hydroxyl, an amine, an acid, or a mixtures thereof;
- wherein o is typically an integer from 0 to 3, and p is 9-30 or when the acid is stearic or palmitic acid, m is 9 or 6.
A surfactant having a formula:
- wherein A is natural oil comprising a plant or animal oil or derivative thereof, a triglyceride group, a fatty acid group, a fatty acid ester group, a fatty acid amide group, or combinations thereof;
- B is a polar hydrophilic group comprising a hydroxyl, an amine, an acid, or combinations thereof;
- and x is 1-9.
