  • Ethyl acetate production
    Patent number: 9079851
    Abstract: A reactive distillation method comprises introducing an feed stream comprising ethanol to a reactive distillation column, contacting the feed stream with a catalyst in the reactive distillation column during a distillation, where the feed stream reacts in the presence of the catalyst to produce a reaction product comprising ethyl acetate and hydrogen, removing ethyl acetate during the distillation from the reactive distillation column as a bottoms stream, and removing hydrogen during the distillation from the reactive distillation column as an overhead stream.
    Type: Grant
    Filed: February 1, 2012
    Date of Patent: July 14, 2015

  • Method of separating dimethyl carbonate and methanol
    Patent number: 6315868
    Abstract: A method of separating methanol and dimethyl carbonate in a distillation column through extractive distillation. The extractive distillation is conducted in the presence of an extractive distillation agent which modifies the azeotropic behavior of the dimethyl carbonate/methanol mixture. A vapor side stream is removed from the distillation column.
