Abstract:
A reaction apparatus for producing a dialkanolamine by causing an alkylene oxide to react with ammonia and a monoalkanolamine, comprising:a first mixer connected both to a source of ammonia and to a source of a monoalkanolamine for mixing ammonia with the monoalkanolamine to form a fluid; a pre-heater, connected to the first mixer, for heating the fluid flowing from the mixer; a second mixer connected to the pre-heater, having a feed inlet for supplying an alkylene oxide, for mixing the alkylene oxide with the heated fluid flowing from the pre-heater; and a reactor connected to the second mixer for receiving the mixture of the heated fluid and the alkylene oxide flowing from the second mixer for reaction therein, wherein the reactor is equipped with a catalyst bed packed with a solid catalyst.
