International Classification:

C07C 67/40
B01J 19/00

US Classification:

560239, 422187

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.

International Classification:

B01D 340
C07C 2732
C07C 6996

US Classification:

203 57

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.

International Classification:

US Classification:

558274

Abstract:

Production of diaryl carbonate esters by reaction of a dialkyl carbonate and an aromatic alcohol to form a diaryl carbonate and an alkyl alcohol is accomplished by introducing three reactant streams into an extractive/reactive distillation column in the presence of a transesterification catalyst. The three reactant streams are a first reactant stream containing a dialkyl carbonate, a second reactant stream containing an aromatic alcohol, and a third reactant stream containing an entraining agent. The entraining agent is selected from among compounds that do not form azeotropes with the dialkyl carbonate or the alkyl alcohol and that boil at a higher temperature than either the dialkyl carbonate or the alkyl alcohol. The first reactant stream is introduced into the column below the second reactant stream, and the second reactant stream is introduced into the column below the third reactant stream. A product stream containing diaryl carbonate esters is recovered from the bottom of the column.
