Blown and stripped plant-based oils |
摘要 |
A method for producing a high viscosity, low volatiles blown stripped plant-based oil is provided. The method may include the steps of: (i) obtaining a plant-based oil; (ii) heating the oil to at least 90C; (iii) passing air through the heated oil to produce a blown oil having a viscosity of at least 200 cSt at 40C; (iv) stripping the blown oil from step (iii) to reduce an acid value of the blown oil to from 5 mg KOH/g to about 9 mg KOH/g; (v) adding a polyol to the stripped oil from (iv); and (vi) stripping the oil from step (v) to reduce the acid value of the oil to less than 5.0 mg KOH/g or less. |

1. A method for producing a high viscosity, low volatiles blown stripped plant-based oil, the method comprising the steps of:
(a) obtaining a plant-based oil; (b) heating the oil to at least 90° C.; (c) passing air through the heated oil to produce a blown oil; (d) stripping the blown oil from step (c) to reduce an acid value of the blown oil to from 5 mg KOH/g to about 9 mg KOH/g; and (e) adding a polyol to the stripped oil from (d); and (f) stripping the oil from step (e) to reduce the acid value of the oil to less than 5.0 mg KOH/g or less. |
