The device has high sealing performance; in the whole purification process, the purification operation can be accomplished by simply controlling the valve and heating; more importantly, trimethyl indium does not precipitate in pipe, and the trimethyl indium can crystallize in a certain particle form; and thus, the requirements on the purity and particle size of the trimethyl indium are met.
Description
Technical field
The purification devices that the present invention relates to a kind of novel trimethyl indium, belongs to technical field of chemical.
Background technology
Trimethyl indium has the nature of danger of meeting air combustion, meeting water blast, and trimethyl indium is solid, and conventional recrystallization etc., owing to will adopting solvent, are easily introduced impurity, cumbersome to its purification process.Therefore, we have developed the purified crystals device of a set of trimethyl indium, can obtain highly purified trimethyl indium.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, a kind of purified crystals device of trimethyl indium is provided.
Object of the present invention is achieved through the following technical solutions:
The purification devices of trimethyl indium, feature is: comprise purification kettle, front-end volatiles equipment of crystallisation by cooling, front-end volatiles receiving tank, product equipment of crystallisation by cooling, product receiving tank and liquid seal can, on described product receiving tank, by valve, connect product equipment of crystallisation by cooling, product equipment of crystallisation by cooling receives valve by product and is connected to purification kettle; On described front-end volatiles receiving tank, by valve, connect front-end volatiles equipment of crystallisation by cooling, in front-end volatiles equipment of crystallisation by cooling, be provided with rotating scraping blade, front-end volatiles equipment of crystallisation by cooling is provided with coil pipe outward, and front-end volatiles equipment of crystallisation by cooling receives valve by front-end volatiles and is connected to purification kettle; Described front-end volatiles receiving tank is also by the valve connecting fluid sealed cans of giving vent to anger.
Further, the purification devices of above-mentioned trimethyl indium, wherein, the connecting pipeline between described product equipment of crystallisation by cooling and purification kettle is provided with heater strip, and the connecting pipeline between described front-end volatiles equipment of crystallisation by cooling and purification kettle is provided with heater strip.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
Apparatus of the present invention have good stopping property, in whole purge process, as long as by-pass valve control and heating just can complete purification process, the most important thing is that trimethyl indium do not separate out in pipeline, and trimethyl indium can be with the crystallization of certain granules shape, finally obtain evengranular trimethyl indium, solved purity and the granularity requirement of trimethyl indium.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: organigram of the present invention.
In figure, the implication of each Reference numeral sees the following form:
Embodiment
As shown in Figure 1, the purification devices of trimethyl indium, comprise purification kettle 1, front-end volatiles equipment of crystallisation by cooling 8, front-end volatiles receiving tank 11, product equipment of crystallisation by cooling 12, product receiving tank 15 and liquid seal can 16, on product receiving tank 15, by valve 14, connect product equipment of crystallisation by cooling 12, product equipment of crystallisation by cooling 12 receives valve 6 by product and is connected to purification kettle 1; On front-end volatiles receiving tank 11, by valve 10, connect front-end volatiles equipment of crystallisation by cooling 8, in front-end volatiles equipment of crystallisation by cooling 8, be provided with rotating scraping blade 7, by rotation, draw together sheet, the trimethyl indium of crystallisation by cooling is dropped in receiving tank, the outer coil pipe that is provided with of front-end volatiles equipment of crystallisation by cooling 8, coil pipe can lead to cooled with liquid nitrogen, and front-end volatiles equipment of crystallisation by cooling 8 receives valve 5 by front-end volatiles and is connected to purification kettle 1; Front-end volatiles receiving tank 11, also by the valve 9 connecting fluid sealed cans 16 of giving vent to anger, is guaranteed to keep anaerobic anhydrous in whole system.On product receiving tank 15, also connect give vent to anger valve 13 and valve 17.The outlet of purification kettle 1 connects stainless steel tube 3 by valve 2, on connecting pipeline on connecting pipeline between product equipment of crystallisation by cooling 12 and purification kettle 1 and between front-end volatiles equipment of crystallisation by cooling 8 and purification kettle 1, be equipped with heater strip 4, guarantee separating out without trimethyl indium in pipeline.
Before purifying starts, by valve 17, whole system displacement is become to nitrogen atmosphere.When purifying starts, open front-end volatiles and receive valve 5, close product and receive valve 6, make lower-boiling impurity crystallization in front-end volatiles receiving tank 11, after front-end volatiles receive and finish, open product and receive valve 6, close front-end volatiles and receive valve 5, make to drop in product receiving tank 15 after product crystallization, after reception finishes, close the valve 13 of giving vent to anger, valve 14, can take off product receiving tank 15.In whole purification process process, heater strip 4 will maintenance work make stainless steel pipeline 3 have certain temperature, guarantees that trimethyl indium is non-crystallizable on pipeline, in order to avoid line clogging.
In sum, apparatus of the present invention have good stopping property, in whole purge process, as long as by-pass valve control and heating just can complete purification process, the most important thing is not crystallization in pipeline of trimethyl indium, and trimethyl indium can finally obtain evengranular trimethyl indium with the crystallization of certain granules shape, solved purity and the granularity requirement of trimethyl indium.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
