Process for the preparation of N-alkylated anilines |
| abstract |
Anilines or N-alkyl-anilines are advantageously reacted with alkyl alcohols or the associated dialkyl ethers at elevated temperature in the gas phase, if a γ-Al 2 O 3 is used that is prepared by dehydration of an aluminum oxide/hydroxide hydrate and has a BET surface area from 50 to 400 m 2 /g and a surface acidity of 5 to 600 mmol H + /kg. |
