Method for producing isocyanates in the gas phase |
摘要 |
An isocyanate is produced by continuously reacting an amine with phosgene in the presence of an inert substance in the gas phase. In this process, a phosgene-containing stream and a stream containing both the amine and the inert substance are fed into a reactor. The molar ratio of the inert substance to the amino groups in the stream is greater than 0 but less than 45 mol %. This molar ratio changes by no more than 99% during a 20 minute period.
