    摘要: The invention relates to an industrial-scale method for the vapor-phase hydrogenation of dinitrotoluene (DNT). According to said method, a stream containing DNT is sprayed into a carrier-gas stream containing hydrogen, optionally in the presence of an atomizing gas, unevaporated liquid droplets are extracted from the substantially gaseous stream that is obtained and the resultant gas stream is catalytically hydrogenated to form diaminotoluene.
