摘要： An improved process for the continuous production of N-alkylarylamines by reaction of arylamines with alkanols and/or dialkyl ethers in the gas phase at a temperature of from 180.degree. to 450.degree.C in the presence of carrier substances which contain an oxyacid of phosphorus. The improvement consists in using silicic acid having an internal surface area of from 50 to 500 square meters per gram and a content of from 0.1 to 20% by weight of phosphoric acid and in the continuous supply of phosphoric acid and/or an alkyl phosphate to the catalyst during the reaction. N-alkylarylamines are starting materials for the production of dyes, pesticides, plant protection agents and growth regulators. They are also suitable as additives to mineral oils or to coating compositions and other polymerized systems.
