Description
Technical field
The present invention relates to Field of Fine Chemicals, more particularly to a kind of preparation method of aluminium bromide.
Background technology
The synthesis of aluminium bromide at present commonly reacts metallic aluminium and bromine, and metallic aluminium reacts very fierce with bromine,
Substantial amounts of heat can be released in course of reaction, if reaction speed control is unreasonable, the blast of reactor may be caused at any time, very
It is dangerous.
Therefore, the reaction rate in aluminium bromide synthetic reaction process how is effectively controlled to prepare in aluminium bromide method
One problem.
The content of the invention
In view of the above-mentioned problems, the present invention proposes a kind of preparation method of aluminium bromide, reaction rate can be effectively controlled.
The present invention solves the above problems by the following technical programs:
A kind of preparation method of aluminium bromide, comprises the following steps：
1) one layer of 30~70cm potsherd is laid on the flase floor of reactor bottom；Repaved on above-mentioned potsherd upper strata
If one layer of 10~30cm active ceramic ring；Aluminium block is laid in above-mentioned active ceramic ring；
2) gaseous bromine is passed through in aforesaid reaction vessel, is reacted with above-mentioned aluminium block, produce product brominated aluminium.
Further, in step (1), potsherd is aluminum oxide or zirconium oxide refractory ceramics piece, is not hindering gas and liquid
The substantial amounts of heat that body can be released while circulation with absorbing reaction, reduce reaction liberated heat to flase floor and the shadow of reactor
Ring.
Further, in step (1), active ceramic ring is microporous activated ceramic ring, larger specific surface area be advantageous to gaseous bromine and
The contact of aluminium block, while pass structure is without prejudice to gas and liquid communication.
Further, boiling point is 58.78 DEG C under simple substance bromine normal temperature and pressure, and in step (2), simple substance bromine is heated to 55~65 DEG C and obtained
The gaseous bromine.
Further, in step (2), gaseous bromine is passed through by the reactor top duct, effectively can be contacted with aluminium block.
Further, in step (2), automatic valve is set at the top of reactor, can timely and effectively control the logical of gaseous bromine
Enter speed, control reaction rate.
Further, in step (2), due to releasing substantial amounts of heat in course of reaction, it is sufficient to aluminium bromide is melted, it is product brominated
Aluminium is now liquid.
Further, in step (2), liquid product aluminium bromide flows to the lamella of reactor bottom, potsherd and active ceramic ring
Structure, liquid product aluminium bromide can flow through between the gap of lamellar structure, be gathered in reactor bottom so that reactant and
Product separates, and is advantageous to the collection of contact and product of the gaseous bromine with aluminium block.
Compared with the conventional method, the advantage of the invention is that：
1) reaction rate can effectively be controlled；Simple substance bromine is heated to form gaseous state, thus when being reacted with aluminium block, can pass through control
The speed that is passed through of gaseous bromine processed effectively controls reaction rate.
2) product and reactants separate；Effective contact area of bromine and aluminium block is ensure that, so that reaction can effectively enter
OK.
3) consersion unit is protected；High-temperature resistant micropore activity ceramic ring and potsherd are laid under aluminium block, can effectively be shifted simultaneously
A part of heat of absorbing reaction, so as to reduce influence of the heat of reaction to reaction vessel.
Brief description of the drawings
Fig. 1 is to prepare aluminium bromide equipment schematic diagram.
Embodiment

Alumina ceramic plate 4 and microporous activated ceramic ring 3, both lamellar structures and pass structure, can increase gaseous bromine
With the contact area of aluminium block, and a part of heat of reaction of transfer both can be absorbed for exotic material, reduce reaction and release
Influence of the heat to flase floor and reactor.
2) to incite somebody to action but simple substance bromine is heated to 55 DEG C, obtained gaseous bromine is passed through in reactor from the top duct 1 of reactor 7, with
Above-mentioned aluminium block 2 reacts, and produces product brominated aluminium, and reaction product flows out and collected in the pipeline 6 from the bottom of reactor 7.
It is certain so as to have when stacking because potsherd and microporous activated ceramic ring are the larger lamellar structure of specific surface area
Space, product liquid hydrogen bromide can from reactor bottom is flowed between space, so as to efficiently separate reactant and product,
Be advantageous to the collection of product while do not influence the reaction of aluminium block and gaseous bromine；The setting of automatic valve can regulate and control gaseous bromine at any time
Be passed through speed, so as to effectively controlling reaction rate, improve reaction yield.
Embodiment 2
1) one layer of 50cm alumina ceramic plate 4 is laid on the flase floor 5 of the bottom of reactor 7；In alumina ceramic plate 4
