  • Accelerated preparation of carboxylic acid esters
    Patent number: 4868329
    Abstract: The instant invention involves a process for preparing carboxylic acid esters which comprises coreacting a carboxylic acid and an aliphatic mono or polyol by maintaining one of the reactants in a reactor at elevated temperatures and adding the other reactant to the reactor over a period of time. By employing this process esterification times are significantly reduced.

    Assignee: Hoechst Celanese Corp.
    Inventors: Thomas M. Powanda, Robert H. Imes, George L. Collins
  • Accelerated preparation of esters
    Patent number: 4859792
    Abstract: The instant invention involves a process for preparing acrylic acid esters which comprises coreacting an acrylic acid and an aliphatic mono or polyol by maintaining one of the reactants in a reactor at elevated temperatures and adding the other reactant to the reactor over a period of time. By employing this process esterification times are reduced significantly.
