EniChem set up a project aimed at the development of a nonphosgene synthesis of DMC for large volume usage as a result, a new industrial process was established, based on a liquid-phase methanol oxidative carbonylation in the presence of copper chlorides as catalysts. This catalytic system was highly effective in DMC production the reaction was carried out by feeding at the same time methanol, carbon monoxide, and oxygen to the suspension of the catalyst in a mixture of water, methanol, and DMC and recovering DMC by distillation after the catalyst separation. Besides, the process... 

A low-pressure process has been developed by ICl operating at about 50 atm (700 psi) using a new active copper-based catalyst at 240°C. The synthesis reaction occurs over a bed of heterogeneous catalyst arranged in either sequential adiabatic beds or placed within heat transfer tubes. The reaction is limited by equilibrium, and methanol concentration at the converter s exit rarely exceeds 7%. The converter effluent is cooled to 40°C to condense product methanol, and the unreacted gases are recycled. Crude methanol from the separator contains water and low levels of by-products, which are removed using a two-column distillation system. Figure 5-5 shows the ICl methanol synthesis process.
