标 题:Facile synthesis of arylmaleic acids and anhydrides
发明人：DEAN WILLIAM D
权利人:AMERICAN CYANAMID CO
摘要:A process for making acrylmaleic acid and arylmaleic anhydride derivative useful as intermediates for the preparation of arylmaleimides in the synthesis of compounds having activity in the central nervous system. The process involves reacting arylacetonitriles with glyoxylic acid to provide novel intermediate 3-aryl-3-cyanopropeneoates which may be converted to the arylmaleic acid and arylmaleic anhydride derivatives.

摘要:The present disclosure provides a non-hydrocarbyl-based alcohol initiated polyetheramine. In particular, the polyetheramine of the present disclosure is produced from a tetrahydrofurfuryl alcohol-based initiator which is alkoxylated and then reductively aminated. The polyetheramine of the present disclosure may be used in a variety of applications, such as a raw material in the synthesis of a dispersant for use in an aqueous pigment dispersion.
