    Abstract: A process for producing phosgene is disclosed which involves contacting a mixture comprising carbon monoxide and chlorine (e.g., at about 300 DEG C or less) with carbon which (1) has a micropore to macropore ratio of 3.5 or less; (2) has a high degree of oxidative stability (i.e., loses about 16 % of its weight, or less, in the WVC Temperature Test as defined herein); and (3) has a minimum surface area of at least 10 m /g. The use of this carbon having an active metal content of 1000 ppm or more is disclosed.
