Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With embodiment, utility model is described in detail below in conjunction with the accompanying drawings.
As it is shown in figure 1, the reaction unit efficiently synthesizing 2-chloro-5-chloromethyl thiazole that the utility model proposes, including chlorine
Changing reactor 1, the top of chlorinating container 1 is provided with the chlorination tube 2 for being passed through chlorine in chlorinating container 1, described chlorination
The bottom of reactor 1 is provided with circulating line 3, and circulating line 3 is provided with circulating pump 4, and this circulating line 3 is connected to a cooling
Still 5, the bottom of this cooling reactor 5 connects has reflux line 10, reflux line 10 to be connected to described chlorinating container 1.Cooling reactor 5
The cooling jacket 11 for heat exchange it is provided with outside kettle.
The thermosol chuck 12 for heat exchange, the top of described chlorinating container 1 it is provided with outside the kettle of chlorinating container 1
Being provided with the scalable and filter tube 6 of band filter, filter tube 6 connects suction filtering tube 13, and suction filtering tube 13 connects has a mother solution to connect
Closed cans 7, mother solution receives the top of tank 7 and is provided with the vacuum tube 8 for drawing liquid.
It is also associated with distillation pipeline 14 on circulating line 3, distillation pipeline 14 is provided with material and twitches pump 15, and this distillation
Pipeline 14 connects a distillating still 9.
Chlorinating container 1, cooling reactor 5 and distillating still 9 are all with stirring structure, and stirring structure includes stirring anchor and stirring electricity
Machine.
Time specifically used, the first material 1-isothiocyanic acid base-2-chloro-2-propene by reaction is molten to 1, in 2-dichloroethanes
And join in chlorinating container 1, chlorination tube 2 it is passed through chlorine；The extraction of material circulating pump 4 on circulating line 3, beats
Enter in cooling reactor 5；It is passed through chilled brine in the cooling jacket 11 of cooling reactor 5 so that internal material cooling, keeps reaction extremely
Qualified, it is then shut off circulating pump 4, then filter tube 6 is directly inserted into the inner bottom part close to chlorinating container 1, be finally then turned on
Vacuum tube 8, vacuum tube 8 starts to take out mother solution reception tank 7 evacuation, is in negative pressure state owing to mother solution receives tank 7, and then passes through
Suction filtering tube 13 makes filter tube 6 carry out the material of chlorinating container 1 filtering extraction, and filtrate is drawn into mother solution and receives in tank 7.
After completing sucking filtration, close vacuum tube, then start in the outside thermosol chuck 12 of chlorinating container 1 to be passed through steam or
