National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Factors Affecting the Production of Phosgene Using gamma Radiation.

PB190029

Publication Date	1970
Personal Author	Landsberg, A.; Block, F. E.
Page Count	19
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)
