Abstract
In an embodiment, a method of producing carbonate can comprise: reacting a feed comprising carbon monoxide and chlorine in a tube of a reactor to produce a product composition comprising phosgene, wherein the tube has a particulate catalyst contained therein, wherein a thermally conductive material separate from the tube contacts at least a portion of the particulate catalyst, and wherein carbon tetrachloride is present in the product composition in an amount of 0 to 10 ppm by volume based on the volume of the phosgene; and reacting a monohydroxy compound with the phosgene to produce the carbonate.
