Description

A kind of airtight safe bromo-reaction device
Technical field
The present invention relates to bromo-reaction device field is and in particular to a kind of airtight safe bromo-reaction device.
Background technology
Bromo-reaction is that a class common are machine synthetic reaction, and brominated reagent is a lot, but by the use of bromine as raw material Bromo-reaction because of high income, good product purity and be widely used.It is but bromine vapor has corrosivity and toxic, Readily volatilized at standard temperature and pressure, form red steam (color is similar to nitrogen dioxide) and have one and chlorine Similar stench, therefore must be very careful when using.Industrial at present or laboratory utilizes the bromo-reaction device of bromine close Have some setbacks because of bromine vapor pressure big impact rate of addition in reactor, severe patient Deca during bad, the direct Deca bromine of envelope property or Person stops.When substrate aromatic multidigit substituted benzene is pressed powder, easily causing powder and waving affects the healthy of the person of feeding intake, Or easily block dog-house, particularly inventory than larger when, charging time greatly prolongs, and increased the contact that raw material is with people Time.Otherwise for the reaction using bromine, direct sample also easily sucks poisonous bromine gas, increased potential safety hazard.
Therefore, these problems how are solved, it has also become those skilled in the art's technical barrier urgently to be resolved hurrily.
Content of the invention
The present invention is directed to the deficiencies in the prior art, there is provided a kind of airtight safe bromo-reaction device, solves Above-mentioned technical problem.
To achieve these goals, the present invention provides following technical scheme：A kind of airtight safe bromo-reaction device, bag Include reactor and the taper loading hopper being tightly connected successively with four openings of reactor head, agitator, constant pressure addition device and Sampler；Described reactor bottom arranges discharging opening, arranges chuck outside reactor；Described taper loading hopper is with reactor even Connect place's setting butterfly valve, outside setting vibrator, top arranges bucket cover；Described constant pressure addition device includes constant pressure addition device body The constant voltage pipeline communicating with constant pressure addition device body lateral opening respectively with two ends；Described constant pressure addition device body bottom goes out A number rotating piston is set at mouthful, and top arranges alkali liquid tank, the junction of alkali liquid tank and constant pressure addition device body arranges No. two rotations Rotoplug；Described sampler is connected with vacuum pump.
In above-mentioned, solid substrate raw material is added by taper loading hopper, and bromine is added by constant pressure addition device, and bromine needs Want fluid-tight to avoid volatilizing, first in constant pressure addition device, add water, be subsequently adding bromine, bromine density conference sinks to bottom.
In above-mentioned, by arranging taper loading hopper, so that disposable inventory is increased, feed intake convenient, when shortening feeds intake Between；Solid can be avoided in the butterfly valve of taper loading hopper and the setting of reactor junction to be blocked in loading hopper by the rotation of valve plate Bottom；Described vibrator can avoid solid material to block simultaneously, after solid feeds intake end, can make to be attached to loading hopper On wall, powder is shaken off in reactor, economizes on resources；Setting bucket cover effect be feed intake at every batch after can directly cover lid Son avoids airborne dust.
In above-mentioned, by arranging constant voltage pipeline at this body side surface of feeding device two ends, make the pressure in reactor and constant voltage The pressure of feeding device is consistent, so that liquid bromine is added smooth；The effect of described alkali liquid tank is to open after the completion of bromine adds Alkali liquor in alkali liquid tank is introduced in constant pressure addition device No. two rotating pistons, can fully absorb on reactor and constant pressure addition device The bromine vapor of side space, is conducive to reacting the post processing after terminating, it is to avoid be directly discharged into atmospheric pollution environment.
In above-mentioned, sampler is connected with vacuum pump, can directly pass through sampling below atmospheric pressure, it is to avoid the bromine that sampling of uncapping causes The danger of steam poisoning；The another one effect of vacuum pump is can be when reaction starts to throw solid material, by opening vacuum Pump makes to keep negative pressure in reactor, contributes to solid and smoothly enters in reactor.
Preferably, described vibrator is arranged on the outside centre position of taper loading hopper, is provided that optimal vibrating effect, prevents The blocking of material in the middle part of only in taper loading hopper.
Preferably, described vibrator is two, is symmetric, makes active force more uniform, vibrating effect is more preferable.
Preferably, described sampler and the junction of reactor arrange transparency cover, can be used as visor observing response device Internal situation, such as observes and has or not a large amount of foams or bromine vapor generation.
Preferably, the sampling vacuum tube of described sampler is passed through inside reactor, makes sampling convenient.
Preferably, at described sampling vacuum tube opening, filter screen is set, is directly filled into unreacted substrate or other solid By-product, it is to avoid be first sampled to outside reaction system in prior art and recycle the extra defecator to carry out filter operation, letter Change operation.
Preferably, described filter screen is 300-400 mesh, reaches the purpose effectively crossing filter solid.
Preferably, described vacuum pump is connected with sample detection means, and the sample of sampling is directly conveyed automatically to detection dress Put, more convenient to operate.
Compared with prior art, the present invention has advantages below：By arranging taper loading hopper and butterfly in reactor head Valve, makes solid feed convenient it is not easy to block and airborne dust；Setting constant pressure addition device makes bromine dropwise adding more smooth；If Put the alkali liquid tank unreacted bromine vapor of absorption and setting sampler avoids contact with poisonous bromine vapor；This apparatus structure is simple, set Count reasonable, easy to operate, sealing and safe, applied widely, it is with a wide range of applications.
