Abstract:
The invention relates to synthesis of methyl carbamate (MC) and dimethyl carbonate (DMC) in presence of stripping inert gas or superheated methanol vapors using packed column reactor and bubble column reactor.

Claim (Index 1):
A horizontal sectionalized bubble column reactor for synthesis of methyl carbamate and dimethyl carbonate (DMC) comprising:\n a. a cylindrical bubble column reactor with single or multiple compartments to receive liquid reactant feed comprising of urea and methanol or methyl carbamate and methanol through inlet ports for a reaction to occur; b. a gas distributor chamber located within the cylindrical bubble column reactor comprising a plate intersecting a cylinder of the cylindrical bubble column reactor with or without an angle to an axis of the cylinder; c. single or multiple inlet ports fitted to the gas distributor chamber for distributing gas; d. single or multiple inlet ports fitted with a constant pressure regulator, single or multiple gas/vapor outlet ports fitted with a back pressure regulator for gaseous phase, wherein, a pressure difference of 10 psi is maintained to ensure positive flow of inert gas into the cylindrical bubble column reactor; e. single or multiple liquid outlet ports with an in-line filter fitted to the cylindrical bubble column reactor for liquid phase withdrawal; f. a heat transfer device fitted to the cylindrical bubble column reactor for maintaining temperature of the reaction; g. a condenser and a gas-liquid separator fitted to the outlet port(s) wherein a product in vapor form is condensed and separated from liquid components; h. an outlet for condensate and an outlet for non-condensate connected to the gas-liquid separator.
