Abstract
A non-phosgene type process for producing urethane, which comprises the following steps: under the presence of a palladium-containing catalyst system, at 80~250 deg.C and 10~200 kg/cm2, catalyzing an aromatic primary amine, an alcohol, CO and an oxygen-containing oxidizer to undergo oxidative carbonylation and synthesize urethane; which is characterized in that the palladium-containing catalyst system contains a palladium and selenium alloy catalyst in which the mole ratio between the palladium atom and the selenium atom is 1:1 to 50:1.
