  • Patent number: 8470932
    Abstract: The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH3—(CH2)n—CH2OH, where n=22-24, are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the presence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than 85° C., and solidifying the acrylate. The methods may thereby provide safe and cost effective methods for curable wax production at large scale.
    Type: Grant
    Filed: April 8, 2010
    Date of Patent: June 25, 2013
    Assignee: Xerox Corporation

  • Patent number: 8207274
    Abstract: The methods of manufacturing a curable wax, such as an acrylate of a hydroxyl-terminated polyethylene wax having the structure CH3—(CH2)n—CH2OH, where n=22-24, and removing a fouled material in a reactor are disclosed. The methods may include reacting a wax having a transformable functional group and a curable compound in the absence of an organic solvent to form an acrylate. The methods may further include removing excess curable compound using hot water having a temperature of more than about 85° C., solidifying the acrylate, removing the acrylate, and removing a fouled material in the reactor by emulsification.

  • Patent number: 7718825
    Abstract: A process for converting an arylamine into an arylamine derivative, includes (i) providing a first arylamine compound; (ii) formylating the first arylamine compound to form a formyl substituted arylamine compound, where the first arylamine compound is not a formyl substituted arylamine compound; and (iii) acidifying the formyl substituted arylamine compound, in the presence of a solvent and a solid organic catalyst, to convert formyl functional groups into acid functional groups to form an acidified compound.
