Description
Technical field
The utility model relates to a kind of chemical reaction instrument, relates in particular to a kind of reactor for gc analysis.
Background technology
The gas chromatography principle of measuring ethyoxyl, hydroxy ethoxy, propoxyl, methoxyl group, propoxyl group equal size in the cellulose ether is the Cai Saier reaction method, also namely utilize hydroiodic acid at high temperature the above-mentioned substituted radical in the cracking cellulose ether generate corresponding idoalkane, utilize organic solvent that idoalkane is extracted then, drawing the supernatant sample introduction separates in gas chromatograph, idoalkane is carried out quantitative assay, thereby converse the amount of above-mentioned substituted radical in the cellulose ether.
This reaction needed is carried out in test tube, need be to test tube mouth sealing and heating test tube during reaction, and domesticly still do not have reaction tube and a heater that is exclusively used in this gas chromatography.Common test tube and heater have following shortcoming: thereby first, generate a large amount of gas in the course of reaction and cause the rapid rising of pressure to cause reaction tube to break easily or seal failure is leaked; The second, course of reaction needs to carry out under hot conditions, and the temperature uniformity between the control accuracy of heating-up temperature and the different test tube is difficult to guarantee.
The utility model content
The technical problems to be solved in the utility model is: the reactor that is used for gc analysis that a kind of good seal is provided.
For the technical scheme that addresses the above problem employing is: the reactor that is used for gc analysis comprises container tube, hermetically-sealed construction and heater, container tube comprises the mouth of pipe, the hermetically-sealed construction sealing orifice, heater heating container pipe, hermetically-sealed construction comprises sealing-plug, friction top and pressed seat, sealing-plug stops up the mouth of pipe, the container tube in the mouth of pipe outside is provided with flange, pressed seat is positioned at the flange below, and friction top is positioned at the flange top and is connected with pressed seat, and friction top compresses sealing-plug.
Further be: hermetically-sealed construction comprises sealing gasket, and sealing gasket is between rubber stopper and friction top.
Further be: hermetically-sealed construction comprises cushion, and cushion is between flange and pressed seat.
Further be: friction top and pressed seat are threaded.
Further be: heater is that thermostat metal is bathed heater, is provided with the test tube hole in the heater, and container tube is positioned at the test tube hole.
The beneficial effects of the utility model are: above-mentioned sealing device seals the container mouth of pipe, flange has effectively limited the displacement that pressed seat makes progress, and friction top is connected with pressed seat, thereby makes the friction top can be to top offset, guarantee that friction top effectively compresses sealing-plug, avoid gas leakage in the container tube.
Select for use thermostat metal to bathe the heater heating, effectively guarantee each container tube heating-up temperature homogeneous.
Description of drawings:
Fig. 1 is the structure of reactor schematic diagram for gc analysis;
Fig. 2 is container tube and hermetically-sealed construction installation diagram;
Be labeled as among the figure: friction top 1, sealing gasket 2, sealing-plug 3, the mouth of pipe 4, flange 5, container tube 6, cushion 7, pressed seat 8, heater 9.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.For a kind of reactor that is used for gc analysis of good seal is provided, the reactor that is used for gc analysis comprises container tube 6, hermetically-sealed construction and heater 9, container tube 6 comprises the mouth of pipe 4, hermetically-sealed construction sealing orifice 4, heater 9 heating container pipes 6, hermetically-sealed construction comprises sealing-plug 3, friction top 1 and pressed seat 8, sealing-plug 3 stops up the mouth of pipe 4, the container tube 6 in the mouth of pipe 4 outsides is provided with flange 5, pressed seat 8 is positioned at flange 5 belows, friction top 1 is positioned at flange 5 tops and is connected with pressed seat 8, and friction top 1 compresses sealing-plug 3.Above-mentioned sealing device line up 4 seals, flange 5 has effectively limited the displacement that pressed seat 8 makes progress, and friction top 1 is connected with pressed seat 8, thereby makes the friction top 1 can be to top offset, guarantee that friction top 1 effectively compresses sealing-plug 3, avoid gas leakage in the container tube 6.The concrete set-up mode of each parts is recommended as follows: container tube 6 is made test tube shaped, and material adopts the high strength glass of thickness 4 ~ 5mm, to improve crushing resistance, avoids container tube 6 to break because internal pressure is too high; Flange 5 has been made one with container tube 6; Sealing-plug 3 is selected rubber stopper for use; Friction top 1 and pressed seat 8 are all selected copper material for use.
Need take out the liquid in the container tube 6 during analysis, take out for convenience, method commonly used is that syringe needle stretches in the container tube 6 and extracts with syringe puncture through seal plug 3.This mode can be destroyed sealing-plug 3, makes sealing-plug 3 be difficult to reuse.In order to save cost, hermetically-sealed construction comprises sealing gasket 2, and sealing gasket 2 is between sealing-plug 3 and friction top 1.During liquid in the evacuation container pipe 6, take off behind the sealing gasket 2 puncture through seal plug 3 again.Sealing gasket 2 only is to cover on the sealing-plug 3, takes off to be easy to.After sealing-plug 3 pierces through, because sealing gasket 2 covers on the sealing-plug, this reactor good seal still when use next time, all parts can both be reused.
In order to guarantee each container tube heating-up temperature homogeneous, heater 9 is bathed heater for thermostat metal, is provided with the test tube hole in the heater 9, and container tube 6 is positioned at the test tube hole.It is prior art that thermostat metal is bathed heater, and sale is arranged on the market, is mainly used in chemical experiment heating test tube, and the advantage of homogeneous heating is arranged.Container tube 6 external diameters make with the test tube hole in can be easily bathe the heater heating with thermostat metal through coupling.
