Abstract
The utility model discloses a kind of liquid, and experimental provision is added dropwise, including syringe, heat tape, solution bottle, syringe is connect with solution bottle by diversion pipe, heat tape is coated on the syringe periphery of syringe, the present apparatus is simple to operation, can realize that the temperature control to reaction raw materials and the distal end to reaction process accurately control.
Description
Technical field
The utility model is related to a kind of chemical experiment device, the product in particular with the production of hot melt raw material compared with high sensitivity
A kind of liquid be added dropwise experimental provision.
Background technology
It is produced using hot melt raw material in the reaction compared with the product of high sensitivity, the safety of experiment is always puzzlement technology people
The big problem of member.In the prior art, it generally requires to carry out flame proof operation.Especially it was added dropwise using separatory funnel progress raw material
Cheng Zhong typically controls the cock of funnel to adjust the charging rate of raw material using operating lever by blast wall.However, this side
Method only solves Partial security sex chromosome mosaicism from surface, is actually unfavorable for the accurate control of liquid dropwise addition and the extent of reaction
System, it is more demanding to the operative skill of operating personnel.In addition, hot melt material is during dropwise addition, due to material to temperature compared with
Material can be caused to be easy cohesion in dropwise addition process, the amount of each drop is very when environment or relatively low reaction vessel temperature for sensitivity
Greatly so that reaction is violent, equally exists larger security risk.What is more, and when temperature dropped to a certain extent, hot melt is former
Material will produce solidification so that reaction cannot carry out.
Invention content
The goal of the invention of the utility model is：In view of the above problems, a kind of liquid dropwise reaction device is provided,
So that hot melt liquid can preferably control temperature during dropwise addition, long-range control accurate to the safety of building-up process is realized
System.
The technical solution adopted in the utility model is such：
A kind of liquid dropwise addition experimental provision, including syringe, heat tape, solution bottle, syringe is with solution bottle by leading
Flow tube connects, and heat tape is coated on the syringe periphery of syringe.
Alternatively, the length of diversion pipe can select according to actual needs, be easy to implement remote control, ensure operation peace
Entirely.
Alternatively, heat tape can connect temperature control device, preferably to control the temperature of liquid in syringe.
Alternatively, diversion pipe is coated with thermal insulation casing, and thermal insulation casing can be polyethylene material, inside set hollow folder
Layer, is passed through circulating hot water and is kept the temperature, avoid liquid temperature change in transmission process.
Alternatively, there is bottle plug on solution bottle, dripping hole is provided on bottle plug, diversion pipe is inserted by dripping hole
In solution bottle.
Alternatively, solution bottle has the lower ending opening structure of liquid separation cock, convenient for taking out synthetic product.
Alternatively, the needle cylinder surface of syringe is provided with graduation mark, in order to preferably measure reaction volume, Yi Jitong
Crossing to change promotes the dynamics of the piston core pin of syringe to carry out coutroi velocity.
The workflow of the utility model：
1, syringe is equipped with the reaction raw materials of suitable dose, and another reaction that suitable dose has been contained in solution bottle is former
Material；
2, heat tape is coated on to the syringe periphery of syringe, the diversion pipe of syringe is connected with solution bottle；
3, the raw material in syringe is heated using heat tape；
4, when temperature reaches requirement, the piston core pin of syringe is pushed, the reaction raw materials in syringe are injected into solution
It is reacted in bottle.
In conclusion by adopting the above-described technical solution, the utility model has the beneficial effects that：
1, temperature control is carried out to reaction liquid using heat tape and thermal insulation casing, avoided due to reaction liquid temperature change
Caused reaction speed is uncontrollable and existing security risk；
2, it is realized to charging by using the piston core pin of propulsion syringe to control the flow velocity of addition reaction liquid
Distal end accurately controls, and ensure that the safety of operation.
Description of the drawings
Fig. 1 is the liquid reactions installation drawing of embodiment.
It is marked in figure：1 is syringe, and 2 be piston core pin, and 3 be diversion pipe, and 4 be heat tape, and 5 be thermal insulation casing, and 6 be molten
Liquid bottle, 7 be bottle plug, and 8 be cock.
Specific implementation mode
Below in conjunction with the accompanying drawings, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
The sensitivity of nitrate esters product is higher, therefore needs flame proof to operate in the synthesis process, and raw materials used is polynary
Alcohol is typical hot melt liquid.As shown in Figure 1, using the stainless steel syringe of 100ml, syringe in the present embodiment
Syringe 1 Heat preservation is carried out using heat tape 4, the diversion pipe 3 of syringe is wrapped with thermal insulation casing 5, and thermal insulation casing 5 is
Polyethylene material inside sets hollow structure, is kept the temperature using hot water circuit, and the front end of diversion pipe 3 is inserted into the bottle plug 7 of solution bottle 6
Dripping hole in.When carrying out synthetic reaction, a certain amount of reaction raw materials polyalcohol is added into syringe, is contained in solution bottle 6
There is the working acid of respective reaction dosage.The piston core of syringe is pushed when the temperature of heat tape 4 reaches technological requirement temperature
Bar 2, polyalcohol, which is injected by diversion pipe 3 in solution bottle 6, to be reacted, and after the completion of reaction, can reverse cock 8 to take out
Reaction product.In the present apparatus, the heating of heat tape 4 realizes the temperature control to raw polyol with the heat preservation of thermal insulation casing 5, leads to
The speed that control piston core pin 2 promotes is crossed to control reaction, and can realize long-range charging, ensure that safe operation.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement etc., should be included in the utility model made by within the spirit and principle of utility model
Protection domain within.
