Description
The amination of 1-bromobutane in an aqueous ammonia solution of 50wt% ammonia using a high-pressure coiled-tube flow reactor was examined. The temperature range studied was from 343 to 403K and the reaction pressure was 13MPa. The major reaction products were n-butylamine and di-n-butylamine, but higher amines, such as tri-n-butylamine, were detected only in trace amounts. Based on a second order consecutive reaction model for the formation of n-butylamine and di-n-butylamine, the reaction rate of amination of 1-bromobutane was determined. Arrhenius parameters for the rate constant of the first reaction step to form n-butylamine were found to have an activation energy of 87.9kJ/mol and pre-exponential factor of 1.03×109mol/(dm3 s), and those for the second reaction step to form di-n-butylamine were found to have the activation energy of 84.3kJ/mol and pre-exponential factor of 4.30×109mol/(dm3 s).
