Description of the drawings
Fig. 1 is structure diagram of the utility model for the reaction kettle of dinitolmide production.
Specific embodiment
As shown in Figure 1, the utility model provides a kind of reaction kettle for dinitolmide production, including ontology 10, sheet
Cover board 11 is provided on body 10, the pre-reaction pipe 20 stretched into inside ontology 10 is provided on cover board 11, pre-reaction pipe 20 is far from lid
The side of plate 11 is provided with the interlayer 27 of closing pre-reaction pipe 20, and perforative leakage fluid dram 28, pre-reaction pipe are offered on interlayer 27
20 sides are provided with the woven hose 25 for reaching 10 outside of ontology, and 25 one end of woven hose is with stretching into pre-reaction pipe 20 and prolonging to interlayer 27
It stretches to form vertical tube 26 (installing check valve at mouth under vertical tube), is additionally provided with along 20 inner wall of pre-reaction pipe and slides in pre-reaction pipe 20
Piston 22, be provided with push rod 21 on piston 22.
In the technical solution, pre-reaction pipe 20 is set to 11 back side of cover board, when lid is closed onto ontology 10 cover board 11 completely,
Pre-reaction pipe 20 is protruded fully into inside ontology 10, in use, can be by strong acid by woven hose 25 and vertical tube 26, to pre-reaction
Then injection strong acid in pipe 20 does pumping movement by push rod 21 with piston 22, the raw material mixed liquor in ontology 10 will at this time
It is drawn into pre-reaction pipe 20 by the leakage fluid dram 28 on interlayer 27, after tentatively being mixed with strong acid, push rod 21 pushes piston 22
Liquid in pre-reaction pipe 20 is injected by leakage fluid dram 28 in ontology 10, since strong acid has tentatively mixed, at this time
Too many heat will not be discharged when being contacted with raw material mixed liquor by entering in ontology 10.It is strong to then proceed to injection in pre-reaction pipe 20
Acid repeats aforesaid operations, until strong acid is injected into several times in ontology 10.The program is due to having the presence of pre-reaction pipe 20, energy
Enough a small amount of in batches of realization strong acid adds in, and controllability is good, and there is no very exothermic problems existing for large dosage while addition.
Further, the formation air inlet 23 of cover board 11 is stretched out in 21 one end of push rod, is provided on piston 22 and connects with air inlet 23
Logical gas outlet 24, wherein air inlet 23 can be connect with air jet system, and then be inflated into pre-reaction pipe 20, pre- so as to improve
Liquid in reaction tube 20 is injected into the initial velocity of ontology 10, so as to improve the dispersion effect of the liquid in pre-reaction pipe 20.
Further, driving motor 30 is fixedly installed on cover board 11,30 lower section of driving motor, which is connected with, stretches into ontology
Agitating shaft 31 inside 10,31 bottom of agitating shaft are provided with " L " the shape agitating paddle 32 for being directed toward 10 side wall of ontology, and agitating shaft 31 drives
When agitating paddle 32 rotates, the stirring track of agitating paddle 32 is in avoidance state with the spatial position of pre-reaction pipe 20.The preferred embodiment
The stirring system being made up of driving motor 30, agitating shaft 31 and agitating paddle 32, exists so as to improve raw material mixed liquor in ontology 10
The mobility after strong acid is added in, heat is avoided to concentrate.Meanwhile agitating paddle 32 uses special " L " shape structure, it can be stirred
Avoid pre-reaction pipe 20 in journey, and the leakage fluid dram 28 of 20 bottom of pre-reaction pipe faces the bottom of agitating paddle 32, therefore from pre-
Reaction tube 20 is injected into the liquid of ontology 10, can first pass around the stirring region of agitating paddle 32, improves dispersion effect.
Further, material inlet 12 is provided on cover board 11,10 bottom of ontology is provided with tapping valve 13.Material can be with
It is entered in ontology 10 by material inlet 12, and can be discharged after completing mixing with mixed solution by tapping valve 13.
The preparation process of dinitolmide mainly passes through following three：Step 1：Nitrification；Step 2：Chloride；Step 3：
Ammonification.It is illustrated with reference to dinitolmide production technology.
（1）O-toluic acid is taken to be placed in reaction kettle, after adding in the concentrated sulfuric acid, stirring dissolves solid（It can low-grade fever）, delay
It is slow to instill concentrated nitric acid.
（2）Reaction temperature maintains 90 DEG C or so, after 2 hours of nitration reaction, adds in cold water cooling, after placing filtering,
With water washing, dried after washing.
（3）Take it is wet it is brilliant add in thionyl chloride, 71 DEG C of chlorination reactions 2 ~ 3 hours（It is clarified to solution）, then it is distilled to recover two
Chlorine sulfoxide adds in chloroform dissolving while hot.
（4）It is slowly added dropwise after chlorination reaction into ammonium hydroxide（25% concentration）In（Ice-water bath）, after being stirred to react 1 hour, direct mistake
Filter, washing washing, drying, obtain drabon color or light yellow solid.
The embodiment of the utility model is described in detail above, but the content is only the preferable of the utility model
