  • Methods of preparing hydroxy functional vegetable oils
    Patent number: 8350070
    Abstract: Simple, economical preparative processes for the provision of pure hydroxyl functional materials that are derived by converting the alkene groups of the unsaturated molecules found in vegetable oils, into hydroxyl groups.
    Type: Grant

  • Method of preparing enhanced reactive vegetable oils
    Publication number: 20090306435
    Abstract: A method of preparing enhanced reactive vegetable oils wherein the method comprises providing a hydroxy functional vegetable oil having a predetermined hydroxyl value and, under nitrogen, treating the hydroxyl functional vegetable oil with a catalyst using heat and pressure. Any water that is formed is removed. The mixture is heated under pressure and then an alkylene oxide is added while heating under pressure. In one embodiment, thereafter, there is added ethylene oxide and the material is heated and then the material is neutralized with acid. This process results in a primary hydroxyl functional vegetable oil polyol that is an enhanced reactive vegetable oil.
