  • Publication number: 20130066090
    Abstract: 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 90° C.; (iii) passing air through the heated oil to produce a blown oil having a viscosity of at least 50 cSt at 40° C.; (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.

  • Patent number: 6958407
    Abstract: A phenyl ester is produced by allowing benzene, a carboxylic acid and molecular oxygen to react with each other in the presence of a catalyst comprising (A) palladium, (B) at least one element selected from elements of groups 13, 14, 15, and 16 and the fourth to sixth periods of the periodic table, and (C) at least one element selected from elements of groups 3, 4 and lanthanoid elements of the periodic table. Preferably, element (B) is selected from elements of group 16 and the fourth to sixth periods of the periodic table, and element (C) is contained in a metal oxide form in the catalyst. The catalytic activity can be maintained at a high level, and a phenyl ester is stably produced. The phenyl ester can be converted to phenol by a conventional procedure.
