Summary: | The invention discloses a microchannel reaction device. The microchannel reaction device comprises a plurality of microchannel reactors connected in series, wherein each microchannel reactor comprisesa casing and an annular passage, each casing is internally provided with a stainless steel pipe and a threaded steel pipe which is sleeved with the corresponding stainless steel pipe, and threads arearranged on the periphery of the threaded steel pipe; and one annular passage of 1 mm is formed between each threaded steel pipe and the corresponding stainless steel pipe. The invention also discloses a method for preparing choline chloride through microchannels, and the method comprises the following steps: pumping ethylene oxide and a trimethylamine hydrochloride solution into a mixer firstly,performing mixing, then introducing the mixture into the microchannel reaction device, collecting output liquid after completion of a reaction, and dehydrating the output liquid so as to obtain the choline chloride.
