Abstract	Experiments were made with a batch reactor to determine the effect of gas pressures, temperature, and gamma radiation intensity on the reaction CO + Cl2 yields COCl2. The equation, dP/d(Theta) = 0.0110(1-0.01t)(sq root of P(CO)I)P(Cl2) where dP/d(Theta) is the change of pressure of phosgene with time (atm/hr), t is the temperature (C), P(CO) and P(Cl2) are the reactant pressures (atm), and I is the radiation intensity (r/hr), was found to best fit the data. Oxygen and a large ratio of reactor surface to volume retarded the reaction, but inert gases had no effect. A low-temperature reactor system is proposed to take advantage of the conditions which give a high reaction rate with gamma radiation and a simple scheme of product purification. (Author)
