The invention discloses a method of preparing an isoquinine ring compound by adopting a micro-channel modular reaction device. The method comprises the following steps of: respectively injecting alcohol liquor of aromatic aldehyde and alcohol liquor of aromatic amine into a first micro-channel modular reaction device by two constant-flow pumps and reacting at a temperature of 85 DEG C-125 DEG C under normal pressure, wherein retention time is 3 minutes-7 minutes; respectively injecting mixed alcohol liquor of cyclohexenone and phosphotungstic acid into a second micro-channel modular reaction device by discharging of the constant-flow pumps and the first micro-channel modular reaction device, and reacting at the temperature of 100 DEG C-140 DEG C under the normal pressure, wherein the retention time is 10 minutes-25 minutes; guiding products into a separator, stewing and layering, and getting supernatant liquid to obtain the isoquinine ring compound. The preparation method of the isoquinine ring compound provided by the invention is a continuous process; moreover, preparation process is simple and easy to operate and control, safety is high, process flow is shortened, production cost is lowered, content of byproducts is lowered, product quality is stable and conversation rate is high.
