Abstract
N , N -Diethylaniline was synthesized from aniline and bromoethane with ionic liquids as phase transfer catalysts under atmospheric pressure. The effects of the various reaction parameters on the yield of N , N -diethylaniline have been studied. The optimum reaction conditions were mole ratio of aniling to bromoethane 1∶2.5, the phase transfer catalyst 1.2 g ( 0.004 mol), the reaction temperature 60 ℃ and the reaction time 6 h under atmospheric pressure. The yield of N, N-diethylaniline reached to above 97%.
