Description
Technical field
The present invention relates to a kind of chemical industry preparation facilities, especially a kind of reactor preparing 5-trifluoromethylaniline.
Background technology
5-trifluoromethylaniline is a kind of important intermediate raw material of chemical field, and it is widely used in the preparation process of various medicine, agricultural chemicals, material.Due to 5-trifluoromethylaniline and prepare the active character of material itself, to make in preparation process intermediate product too much, cause the waste of material and the lower problem of purifying rate.Chinese utility model patent CN201753332U discloses a kind of synthesizer of 2,4,6-trimethylaniline, although certain effect reducing costs and improve purifying rate can be played, but its complex structure, integrated rate is low, the more important thing is that it reduces costs and improves the effect of purifying rate and not obvious, package cost, floor space and later maintenance expense, improve without obvious economic benefit.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of reactor preparing 5-trifluoromethylaniline, and can solve the deficiencies in the prior art, compact conformation, production efficiency is high, significantly improves the economic benefit preparing 5-trifluoromethylaniline.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows.
A kind of reactor preparing 5-trifluoromethylaniline, comprise tank body, stirring rod is provided with in tank body, the sidewall of described tank body is provided with several reactive tanks, the height of each reactive tank on tank body is different, the bottom of tank body and the sidewall of reactive tank are respectively arranged with heater, the bottom of tank body is also provided with lth layer, described stirring rod is provided with and reactive tank paddle one to one, paddle and reactive tank corresponding are with it in sustained height, first feed pipe through with stirring rod is provided with in paddle, first feed pipe is communicated with tank interior by paddle, the second feed pipe is provided with in reactive tank.
As preferably, be provided with baffle plate in described reactive tank, reactive tank is isolated into upper groove body and lower groove by baffle plate, is provided with reducing in upper groove body, is provided with rotating vane in lower groove.
As preferably, described rotating vane top is provided with oven wire mesh blanket.
As preferably, described upper groove body is 1: 3 ~ 1: 1 with the ratio of the volume of lower groove.
As preferably, the sidewall of described lower groove is provided with through hole, is provided with deflection plate inside through hole.
As preferably, be provided with the turbulence plate be crisscross arranged in described first feed pipe, the outlet of the first feed pipe is provided with atomizer.
As preferably, described paddle is connected by frictional damping layer with stirring rod, frictional damping layer and movablely between paddle and stirring rod to arrange, and paddle arranged outside has retainer ring.
The beneficial effect that brings of technique scheme is adopted to be: in the preparation process that the reactor inside that the present invention is directed to prior art cannot be carried out high-precision hybrid reaction and be caused, intermediate product is too much, cause the waste of material and the lower problem of purifying rate, carried out improving targetedly.The reactive tank highly differed defines semi-enclosed reaction compartment at tank body, for the interpolation of differential responses thing.The first feed pipe on paddle corresponding with it can pass into the raw material of corresponding complex reaction.Due to reactive tank and paddle one_to_one corresponding, greatly can improve the reaction effect of each concrete local reaction, reduce the generation of intermediate product.By controlling the liquid level in tank body, different reactive tanks can be realized and be on liquid level respectively and under the page, and then achieving the different choice of direct solubilizing reaction and gas diffusion reaction.Lower groove divides in order to storing part and output section by through hole, deflection plate can reduce change in flow rate during fluid turnover through hole, reducing can improve the local velocity of fluid, rotating vane can rotate under the effect of fluid flowing, improve the equal rate of reaction in reactive tank, the oven wire mesh blanket at top can improve the active area of whipping process.Material is evenly sprayed from the first feed pipe by turbulence plate and atomizer, can match with reactive tank, improves effective reaction rate.By retainer ring, the adjustment of power is accommodated to paddle, different frictional damping transmissions can be realized, thus realize different paddle there is different mixing speeds.
