The invention discloses a device and method for continuously preparing
tetramethylammonium hydroxide, aiming to solve the problems of high production cost and high
impurity content of the existing
tetramethylammonium hydroxide production methods. The device comprises an
ion exchange column, an
electrolytic cell, an
anode material tank, a
cathode material tank, a
cathode gas
storage tank, an
anode gas
storage tank, a boiler, a heating trough, a first liquid pump, a second liquid pump, a third liquid pump, a first pipeline, a second pipeline, a third pipeline and a fourth pipeline. In the method, a tetramethyl
ammonium bicarbonate aqueous solution is taken as
anode liquor, a tetramethyl
ammonium hydroxide dilute solution is taken as
cathode liquor, through the mutual cooperation of the production device and a process, the process flow can be effectively shortened, and the production cost can be significantly reduced. The device and method disclosed by the invention are short in process flow, simple in operation and low in production cost, and prepared products are high in purity and high in yield, so that the energy efficiency is effectively reduced, and the defects of high
power consumption and low current efficiency existing in the prior art are overcome, therefore, the device and method disclosed by the invention can adapt to the needs of industrial production.
