  • Patent number: 10196585
    Abstract: A method for producing a blown and stripped biorenewable oil is provided. The method may include the steps of (a) heating a biorenewable oil to at least 90° C.; (b) exposing an oxygen containing stream to the heated oil to produce a blown oil having a viscosity of at least 40 cSt at 40° C.; (c) adding a base metal catalyst to the blown oil; and (d) stripping the blown oil from step (c) until the stripped oil has an acid value of from about 1 mg KOH/g to about 20 mg KOH/g; wherein the stripped oil from step (d) has a flash point of at least 220° C.

  • Patent number: 10150827
    Abstract: Imidazoline functionalized oxidized fatty substance emulsifiers are made by obtaining a fatty substance composition; performing an oxidative oligomerization of the fatty substance composition to produce an oxidized fatty substance composition comprising from about 10 to about 75% by weight of oligomeric fatty acid components based on the total weight of fatty acid containing components in the composition; reacting the oxidized fatty substance composition with a polyamine comprising at least one ethylene diamine functional group with at least three hydrogens attached to the two nitrogens to form an aminoethylamido functionalized oxidized fatty substance composition; and forming an imidazoline functionalized oxidized fatty substance emulsifier from the aminoethylamido functionalized oxidized fatty substance composition. Such compositions are particularly useful in asphalt applications and corrosion inhibition.
