Description
Technical field
The utility model relates to a kind of meta-xylene chlorination reaction still, belongs to technical field of chemical.
Background technology
The meta-xylene chlorizate is mainly used in the preparation of m-terephthal aldehyde, and m-terephthal aldehyde is mainly used in the industry such as dyestuff, fluorescent whitening agent, medicine, spices, is the important source material of organic synthesis and fine chemistry industry.Simultaneously because it has two active aldehydes, so it can autohemagglutination, can form with other monomer copolymerization again the macromolecular compound of various performances, be the important monomer of synthesized polymer material.M-terephthal aldehyde is along with expansion and the use amount of its range of application increase in recent years, and it is large to have formed market potential, the fine chemical product that vitality is strong.Its not only demand for exports amount increases, and the domestic demand amount is also considerable.Under current situation, the yield that improves the m-terephthal aldehyde product is a considerable task.In existing meta-xylene optical chlorinating reaction still, generally be divided into two kinds: a kind of for not with the reactor of stirring, this reactor operation principle is deeply to insert fluorescent tube in the reactor, by the logical chlorine from the bottom, the air-blowing bubble reaches the effect of stirring, and the method defective is that chlorine can not fully contact with meta-xylene; Another kind of reactor for the normal tape stirring, the shortcoming of this reactor is and the lamp sleeve pipe can not be inserted in the reactor deeply that lighting effect is bad, also may cause potential safety hazard, long-time vibration may be broken and be dropped in the reactant liquor such as fluorescent tube, and the liquid combustion explosion induces reaction.
Summary of the invention
The purpose of this utility model is to overcome the defective of existing reactor, provides a kind of sufficient reacting, lighting effect good, without the meta-xylene chlorination reaction still of potential safety hazard.
The technical solution of the utility model is:
A kind of meta-xylene chlorination reaction still, it is by the reactor kettle, motor, agitator consists of, be provided with agitator in the reactor kettle, reactor kettle top is provided with motor, motor is connected with agitator, it is characterized in that: described reactor kettle is one to cover the interlayer body of tubbiness, the bottom of reactor kettle is by the tank card, rubber gasket and gripper shoe are equipped with the quartz glass base plate, the quartz glass base plate middle part of agitator below is provided with discharging opening, be provided with the chlorine distributor pipe in the discharging opening, be respectively arranged with charging aperture and thermometer installing port on the reactor kettle of motor both sides, thermometer inserts by installing port and is installed in the reactor kettle; Reactor kettle one side of quartz glass base plate top is provided with the chuck delivery port, and the opposite side of reactor kettle is provided with the chuck water inlet, and described quartz glass floor below is provided with ultraviolet source.
The beneficial effects of the utility model are:
This meta-xylene chlorination reaction still carries out illumination by the quartz glass base plate of bottom, strengthened illuminating area, strengthened lighting effect, can guarantee the photocatalysis needs that chlorination reaction is required, can reach by uniform stirring again the purpose of abundant reaction, external ultraviolet source can take full advantage of, the lamp long service life, do not need frequent cleaning during shutdown reactor, the visual advantage that possesses glass kettle, because ultraviolet source is arranged on the kettle outside, avoided the easy high temperature cabonization of existing Built-in light sleeve pipe, the insecurity factor of built-in light source high temperature decrepitate lamp sleeve pipe simultaneously.Under the prerequisite that guarantees security, the muriatic content of meta-xylene and yield have been improved.
