(57) [Abstract] [Problem] Carbon tetrachloride, chlorine molecule, etc. (particularly carbon tetrachloride) Provided are a method for efficiently producing phosgene having a small amount of impurities and a polycarbonate resin. SOLUTION: The packing density is 0.42 as a phosgenation catalyst. 0 to 0.455 g / ml, specific surface area 1200 to 1300 m 2 / g, pore volume 0.90-1.00 ml / g, grain density 0.65-0.80 g / ml, average pore diameter 1.65- 1. A method for producing phosgene, comprising producing phosgene using activated carbon of 1.95 nm and then distilling the phosgene, and a polycarbonate resin obtained by reacting the phosgene with a dihydric phenol. |
