TH34678A - Methacrylate Ester Preparation Process - Google Patents

Abstract

DC60 (12/09/49) The methacrylate ester preparation process where (a) propine is wiped out of the conductor current. Dissolved in a distillation column containing dissolved propine The gas propane stream is Condensate later and (b) the condensed propine is exposed to carbon monoxide And alcohol with a catalyst for the carbonization reaction included. The peculiarity is that the propine that is swept into the distillation column is connected to the internal condenser. In order to create some condensation for transport, the distillation is re-circulated. The methacrylate ester preparation process, where (a) pyrpine is wiped out of the solvent stream in the distillation column containing dissolved propine, the proppine that The gas is subsequently condensed into a liquid and (b) the condensed propine is exposed to carbon monoxide and catalyst alkaloid for the carburization. Bonile floor is included. The nature of the propine that is swept into the distillation column is connected to an internal condenser to create some condensation for re-flow distillation.

Claims (8)

1. The methacrylate ester preparation process where (a) propine is swept into the solvent distillation column containing dissolved propine. So that the gas propine current is subsequently condensed and (b) the condensed propine is exposed to carbon monoxide and alcohol, with catalyst for the reaction Carbonation is also present. Which is characterized by that the propine that is swept into the distillation column is connected to the internal condenser. To partially form condensation to return to reflux 2. The process referred to in claim 1, where the gaseous propine is subsequently condensed in all the above condensers. It is collected in a collection tank, which is then mixed with alcohol. 3.
