The invention discloses a continuous preparation method of
zinc thiazole, which comprises the following steps: pumping a thiadiazole
salt solution and a
zinc salt solution serving as a
stream 1 and a
stream 2 into a continuous stirring reactor, controlling the flow rates of the
stream 1 and the stream 2 to ensure that the
mass ratio of thiadiazole salt to
zinc salt in the reactor is 2: (0.5-1.5), and continuously stirring at the temperature of 20-90 DEG C and the stirring rate of 300-800 r / min to obtain zinc
thiazole. Continuously preparing to obtain turbid liquid containing the product zinc
thiazole, concentrating and filtering the obtained turbid liquid through a PM membrane, and
drying a
filter cake to obtain a zinc thiazole
active compound; or adding an auxiliary agent acceptable in
pesticide science into the obtained suspension containing the zinc thiazole, and uniformly mixing to obtain the zinc thiazole suspending agent, the method is simple in equipment operation and low in
energy consumption, the reaction conversion rate is increased by controlling the temperature of the reactor and the stirring speed, and the method is different from a traditional strategy of preparing zinc thiazole by using a
batch reactor, can realize
continuous production and is suitable for large-scale industrial application.
