Make to cause production cost too high, which greatly limits its application.Therefore, development is the simplest, productivity is higher
It is the most necessary that synthesis technique and equipment make it industrially obtain larger range of popularization, has highly important practical significance.
Disilicoethane spontaneous combustion in atmosphere, ignition point is room temperature, runs into the just burning of air moment, and is decomposed into SiH4With
H2.Burning concentration wide ranges, time more than 0.2%, burning sends flame, time below 0.2%, carries out oxidation reaction and generates white
SiO2, the most explosively burn in chlorine, explosively react with halogen gas, as at low temperature, the most moderately carry out halogen
Change, with SF6Contact is then exploded, and with carbon tetrachloride and chloroform intense reaction, reacts decomposition with alkali metal and amalgam and generates silane
And hydrogen, dissociate H with caustic potash effect2, do not react with pure water and acid, but generate silicate and hydrogen with alkali reaction.Even if from glass
Glass dissolves the existence of the trace alkali, Disilicoethane also can be made to hydrolyze.In the presence of KH or LiCl impurity, also delay at room temperature
Slowly decompose.
Si2H6—→ SiH4+(SiH2)x
Disilicoethane dissolves in Carbon bisulfide, ethyl alcohol, benzene and ethyl silicic acid.Its corrosion rubber, butter class, lubricating oil, lead etc., but
Most metals is not corroded.Prior art Disilicoethane needs to keep relatively low temperature in stowing operation, and in device for filling
There is cooling vent in portion, can there is the problem that on cooling vent and other positions, cooling effect is uneven in cooling procedure.

Lower filling Disilicoethane, it is ensured that the filling effect of storage tank, it is to avoid the generation of the too early flooded condition of storage tank, simultaneously by vacuum jacket
Design, improves the cooling effect of Disilicoethane, it is to avoid the impact that Disilicoethane is stored by ambient temperature.
Accompanying drawing explanation
Fig. 1 is the structural representation of Disilicoethane storage tank of the present invention.
In figure, 1-seals and fills storehouse, 2-vacuum jacket, 3-bracing frame, 4-filling mouth, 5-locating slot.
Detailed description of the invention
For further appreciating that present disclosure, feature and effect, below in conjunction with drawings and Examples, detailed to the present invention
Explanation.
Refering to Fig. 1, a kind of Disilicoethane storage tank, fill storehouse 1, vacuum jacket 2 and bracing frame 3, described sealing including sealing
Filling storehouse is cylindrical housings, and the outside of described cylindrical housings is vacuum jacket, is-30 DEG C of glycol-cooled in described chuck
Medium, described cylindrical housings is vertically fixed on bracing frame, and the described top sealing filling storehouse 1 is provided with filling mouth 4, described close
Packing fills the bottom in storehouse 1 and is provided with the locating slot 5 of depression.
For the ease of understanding the application, the existing silane product manufacturing process by use the application Disilicoethane storage tank is carried out simply
Introduce.Described silane product manufacturing process comprises the steps of
A, first generate magnesium silicide with silica flour and magnesium powder,
Si+2Mg------→Mg2Si
B, react with ammonia chloride with magnesium silicide, in the environment of liquefied ammonia and catalyst, generate silanes and magnesium chloride hexammoniate, reaction
Formula is:
NH3(l)
Mg2Si+NH4Cl----------------→SinHm+MgCl2•6NH3+H2
Catalyst
Wherein m=2n+2
C, magnesium chloride hexammoniate are a solids product, then obtain magnesium chloride and liquefied ammonia through separating reaction in addition, and liquefied ammonia can be thrown again
Enter in above-mentioned processing procedure B and following processing procedure E and use:
MgCl2•6NH3----------→MgCl2+6NH3
D, magnesium chloride also generate magnesium powder and chlorine again through electrolysis, and magnesium powder is solid phase, can put in the A in above-mentioned processing procedure and make
With:
MgCl2--------→Mg+Cl2
Electrolysis
E, chlorine generate ammonia chloride with liquefied ammonia synthetic reaction again, and ammonia chloride is put into the B in above-mentioned processing procedure and uses, wherein liquefied ammonia
Coming from the C in above-mentioned processing procedure, in other words, the ammonia of processing procedure C generation can use for processing procedure B and E:
Cl2+H2-------→2HCl
NH3+HCl-------→NH4CL
Formula generates in step B the product of silanes from the reactions above, although monosilane and Disilicoethane are all gas, but molecule
Amount is had nothing in common with each other, and causes the temperature required difference that liquefies/gasify.Use its physical characteristic different, can respectively obtain through separating
Monosilane, Disilicoethane product, to allow the variant paraffinic product side of being individually present be answered different use demand.Specific works process
As follows: reactor admixture of gas out enters the rectification tower system of series connection, controls the temperature in rectifying tower, cools to-1200C to-1700C, isolates Disilicoethane: cool to-170 the most again0C to-196 0C, isolates monosilane.The first silicon that will obtain
Alkane is warming up to-1700More than C, makes monosilane become gas phase from liquid phase, lowers the temperature, in-180 0C to-1960In C temperature
Obtain high-purity monosilane；The Disilicoethane obtained is warming up to-1200More than C, makes Disilicoethane become gas phase from liquid phase, then
Lower the temperature again, in-1300C to-1600C temperature obtains high-purity Disilicoethane, high-purity Disilicoethane is sent into Disilicoethane storage tank,
After measured, Disilicoethane purity is up to 99.998%.
