PREPARATION OF N-ALKYLATED ANILINE

PREPARATION OF N-ALKYLATED ANILINE

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 gamma -Al2O3 is used that is prepared by dehydration of an aluminum oxide/hydroxide hydrate and has a BET surface area from 50 to 400 m2/g and a...

Zusammenfassung: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 gamma -Al2O3 is used that is prepared by dehydration of an aluminum oxide/hydroxide hydrate and has a BET surface area from 50 to 400 m2/g and a surface acidity of 5 to 600 mmol H+/kg.
