text: Summarizing, it can be stated that the process according to the invention has a high phosgene destruction capacity even at low temperatures, i.e. that even at these temperatures phosgene is analytically no longer detectable in the gas leaving the active carbon bed, and the reaction can be carried out in a small apparatus.
text: Analytically, phosgene is no longer detectable in the off-gas leaving the column, even after 24 hours' operation.
text: After the phosgene-containing mixture has been introduced for 1 minute, phosgene is already detectable analytically in the off-gas.
text: Even after 3 months' operation, no phosgene is detectable in the off-gas leaving column 8.
