Abstract
A method for producing a high viscosity, low volatiles blown stripped oil blend is provided. The method may include the steps of: (i) obtaining an oil blend of corn stillage oil and soybean oil having a weight ratio of corn stillage oil to soybean oil of from about 1:2 to 3:1; (ii) heating the oil blend to at least 90° C.; (iii) passing air through the heated oil blend to produce a blown oil having a viscosity of at least 50 cSt at 40° C.; and (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram.
Claims11
A method for producing a high viscosity, low volatiles blown polymerized plant-based oil, the method comprising the steps of:
- (a) obtaining a plant-based oil;
- (b) heating the plant-based oil to a temperate of from about 100° C. to 120° C.;
- (c) passing air through the heated plant-based oil to produce a blown plant-based oil having a viscosity of at least 50 cSt at 40° C.;
- (d) stripping the blown plant-based oil at a temperature of from about 230° C. to about 270° C. to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram;
- (e) adding glycerin during step (d);
- and
- (f) producing a polymerized plant-based oil having a viscosity at 40° C. of at least about 300 cSt.
