In fine chemistry industry production, carrying out producing in general is reacted using reactor.Reactor is single independent appearance
Device, be made up of kettle, kettle cover, chuck, agitator, transmission device, gland seal device and supporting etc., capacity by 0.5m3-20m3 not
Deng.
Aforesaid reaction vessel part is more, limited volume, can only single batch reaction, the size of reactor directly determines yield,
Because the extent of reaction is different in kettle, reactor can not carry out continuous feed production, and as reactor solvent is bigger, reactor
Diameter is bigger, and material stirring becomes uneven in kettle, and material reaction becomes more incomplete.
Synthetic reaction often relates to the conditions such as high temperature and high pressure, due to reactor include kettle, kettle cover, chuck, agitator,
The parts such as transmission device, gland seal device and supporting, at high temperature under high pressure, the stability of part and the sealing of reactor will be by
To very test, once there is a part to go wrong, caused by causality loss be likely to measure.
Need to maintain temperature for reaction, and without organic synthesis caused by gas in reaction, it is desirable to provide it is a kind of
Equipment, the equipment are not only simple in structure, and parts are few；And can keep reacting required temperature and pressure, and can causes
Reaction is carried out completely, and this equipment can improve production efficiency, reduces the production time, and the continuous production reached to a certain extent is made
With.
The content of the invention
For small-sized fine chemistry industry enterprise described in above-mentioned background technology in production tetrabutyl urea, 2- EAQs, two different
In butyl carbinol and methylcyclohexyl acetate chemical combination course of reaction, the original excessive due to the size parts of reactor of appearance
Because the reaction speed brought is slow, reaction not exclusively, low production efficiency, unstable production the problem of, our factory passes through a large amount of scene examinations
Test, devise that a kind of device structure is simple, production efficiency is high, the production time is short, reaction completely and is able to maintain that HTHP
A kind of pipeline reactor for fine chemistry industry production.

Temperature, and steam inlet is arranged at the upside of the other end of material outlet；Steam (vapor) outlet is arranged at the other end of material inlet
Downside.
Further it is technically characterized in that：The pipeline reactor is a straight pipe reactor, or bent-tube boiler reaction
Device；The pipeline reactor is made up of four straight tube parallel combinations installations.
Implement a kind of above-mentioned pipeline reactor for fine chemistry industry production provided by the utility model, it is and existing small-sized
Fine chemistry industry enterprise production tetrabutyl urea, 2- EAQs, diisobutyl carbinol (DIBC), the autoclave used in methylcyclohexyl acetate are anti-
Device is answered to compare, the utility model, by a duct-like main reactor, and sets turbulent flow internals to allow thing by material in pipeline
Expect real-time hybrid reaction, main reaction pipeline peripheral hardware is equipped with high-performance heat exchanger, and heat exchanger is connected by ring flange, wherein steam (vapor) outlet
Close to main reaction pipeline material inlet, close to main reaction pipeline material outlet, reason is in the first of combination reaction for steam inlet
Stage beginning, it is not necessary to which too high temperature carrys out initiation reaction, and reacts and can release the progress that heat carrys out maintenance reaction, has arrived reaction
Later stage, exothermic heat of reaction reduces, and reacted material has solidification to be changed into the risk of solid, it is necessary to which higher temperature is incubated.
This pipeline reactor produces for fine chemistry industry, and main reaction position is pipeline, and diameter is small, and material is well mixed, instead
Should be complete, realize one end continuous feed, successive reaction in pipe, one end continuous discharge, shorten small-sized fine chemistry industry production
Continuous reaction time, production efficiency is improved, reduce the error rate of consersion unit, be really achieved practical purpose, especially
It is small-sized fine chemistry industry manufacturing enterprise.
