Metallic soap compositions for various applications
View Patent ↗Metallic soap compositions for use in various applications, including as adhesives, as having anti-corrosion properties on certain surfaces or materials, and as asphalt modifiers to reduce viscosity in an asphalt mixture, and process for making the same, are disclosed. The processes comprise at least a partial saponification of a mixture of an oil, often a natural oil which may be hydrogenated and/or metathesized, and a metal compound via a fusion process, or may comprise at least a partial saponification of a mixture of a similar oil and a metal compound, or optionally a fatty acid derived from a similar oil, via an aqueous process, with an optional addition of an inorganic metal salt via at least one ion exchange reaction.
1. A method of forming a metallic soap composition, the method comprising:
(a) introducing an oil to a reactor, wherein the oil comprises a self-metathesized natural oil, a hydrogenated self-metathesized natural oil, or a mixture thereof;
(b) heating and purging the oil in the reactor at a temperature between about 70° C. and about 140° C. in a nitrogenous atmosphere;
(c) introducing a metal compound to the oil in the reactor to form a mixture, and heating and purging the mixture at a temperature between about 200° C. and about 400° C. in a nitrogenous atmosphere to form a partially saponified oil, wherein the metal compound comprises metal oxides, metal hydroxides, metal carbonates, metal alkoxides, or mixtures thereof; and
(d) cooling the partially saponified oil to obtain a metallic soap composition.
2. The method of claim 1 , wherein said metal compound is a metal hydroxide selected from the group consisting of calcium hydroxide, strontium hydroxide, lithium hydroxide, sodium hydroxide, potassium hydroxide, and magnesium hydroxide.
3. The method of claim 1 , wherein said natural oil is selected from the group consisting of canola oil, rapeseed oil, coconut oil, corn oil, cottonseed oil, olive oil, palm oil, peanut oil, safflower oil, sesame oil, soybean oil, sunflower oil, linseed oil, palm kernel oil, tung oil, jatropha oil, mustard oil, pennycress oil, camellina oil, castor oil, lard, tallow, poultry fat, yellow grease, algal oil, fish oil, tall oils, and mixtures thereof.
4. The method of claim 1 , wherein said partial saponification comprises between about 10 percent to about 100 percent saponification as measured by FTIR.
