The invention provides a multifunctional chemical experimental connector, which relates to the separation technology, chemical technology, glass apparatus and other fields. The connector integrates functions of a constant pressure dropping funnel, a Soxhlet extractor, a water separator, an oil separator, a vacuum connection leading pipe, a fractional head and the like, and is composed of a fractional column, a temperature measurement chamber, a liquid storage chamber with scale, a side tube, a two-way inside three-way outside piston, an inner ground interface, an external ground interface t and a vacuum connection leading pipe. The connector has the advantages of reasonable design, simple structure, strong function, standard operation and convenient usage.

Description

Multifunctional chemical experiment connector

1. technical field

The present invention relates to fields such as organic synthesis, isolation technics, chemical process, glass apparatus.

2. technical background

Existing chemical synthesis glass apparatus; In teaching, find broad application in the research and production, these glass apparatus are of a great variety, function is different, cheap, can realize associative operation through assembling all; But these operations all are through assembling basically by single glass apparatus; The principle of assembling all is " from bottom to top, from left to right ", unload then just in time on the contrary, and assembling, to unload experimental provision time-consuming loaded down with trivial details again.More advanced synthesizer has the parallel synthesizer of Biotage, the parallel synthesizer of KEM, Chemspeed combinatorial chemistry synthesizer, Radleys synthesizer etc. at present; These automation equipment degree are higher; But cost an arm and a leg, maintenance cost is high, can't satisfy teaching, scientific research needs.

The present invention provides a kind of multifunctional chemical experiment connector, can realize assembling, the unloading of standard mouth glass apparatus easily through this multifrnction connector.Assemble method is: earlier with the fixing multifunctional chemical connector of the iron stand that has iron clamp; Put reactor (like round-bottomed flask etc.), thermometer, reflux condensing tube, receiving bottle etc. as required respectively; Reactor and connector clamp with the cone-shaped interface folder, are exactly an integral body owing to used cone-shaped interface folder, whole device; Through to the moving up and down of cross clamp, just handle assembly is fixed on suitable height easily; Discharging method is also very easy, and what what just unloads to think unloading earlier, need not carry out according to the reverse principle of " from bottom to top, from left to right ".

3. summary of the invention

The present invention has integrated the function of constant pressure funnel, Soxhlet extractor, water knockout drum, separator, liquid measuring vessel, receiver (normal pressure or decompression), the first-class instrument of fractionation; 1., this multifrnction connector can realize assembling, the unloading of standard mouth glass apparatus easily can replace constant pressure funnel, Soxhlet extractor, water knockout drum, separator, liquid measuring vessel, receiver (normal pressure or decompression), the first-class instrument of fractionation fully, its multi-functional performance is following:; 2., can realize easily monitoring and slip out the liquid boiling range in the course of reaction; 3., in decompression distillation operation because fluid reservoir can store certain amount of fluid,, can under the prerequisite that does not influence vacuum fractionation, change the product of receiving bottle at any time with the reception different boiling ranges through regulating interior two logical outer stop,threeways; 4., through two logical outer stop,threeways in regulating; Realize operations such as backflow, Fen Shui, branch oil or drying, make intermittently operated become continued operation, because whole operation is accomplished near enclosed environment; Reduce the product loss that intermittently operated brings, improved the quality and the output of product; 5.,---liquid or solid---liquid continuous extration operation that overcome Soxhlet extractor shortcoming, liquid and evaporation and concentration operation only need in the adjustment two to lead to outer stop,threeways (16) and can accomplish; 6., realize continuous steam distillation, dress distillate and water adds thermal distillation in flask, distillate condensing is in fluid reservoir; Through regulating interior two logical outer stop,threeways (10,16), organic matter can be emitted at any time; Water returns flask, recycles, and this device has saved steam generator; Easy, energy-conservation, economize the people and save trouble, continuously, efficiently, need not add new water, also can reduce the water-soluble loss of product.7., realize the multiple function of Rotary Evaporators, be equipped with magnetic stirring apparatus, can realize functions such as decompression distillation operation easily without zeolite.

4. description of drawings

Fig. 1 is a structural representation of the present invention, and wherein 1 is the outer grinding port joint, and 2 is brace summer, and 3 is still, and 4 is the glass filler; 5 is the thermometric chamber, and 6 is interior ground interface, and 7 is side pipe, and 8 is interior ground interface, and 9 is side pipe; 10 is interior two logical outer stop,threeways, and 11 are band scale fluid reservoir, and 12 is communicating pipe, and 13 is the receiver outer tube; 14 is pipe in the receiver, and 15 is the outer grinding port joint, and 16 is interior two logical outer stop,threeways, and 17 is side pipe.

The present invention is by still (3), thermometric chamber (5), band scale fluid reservoir (11), side pipe (7,9,17), interior two logical outer stop,threeways (10; 16), outer grinding port joint (1,15), interior ground interface (6,8) and vacuum connect skirt (13-14-15) composition; It is characterized in that fluid reservoir (11) upper end is interior ground interface (8); The lower end is connected with interior two logical outer stop,threeways (16), and upper left side pipe (7) is communicated with thermometric chamber (5), and upper right side pipe (9) is connected with interior two logical outer stop,threeways (10); Thermometric chamber (5) and still (3) sidewall are communicated with side pipe (7), side pipe (17) respectively, and side pipe (7), side pipe (17) are connected with upside, the interior two logical outer stop,threeways (16) of fluid reservoir (11) respectively again simultaneously; In two logical outer stop,threeways (16) be connected with the interior pipe that the vacuum of declivity connects skirt (13-14-15) again, the outer tube sleeve that vacuum connects skirt (13-14-15) is on inner pipe; In two logical outer stop,threeways (10) be connected with the outer tube that the vacuum of declivity connects skirt (13-14-15) again; Fluid reservoir can have the graduation mark of measuring liquid volume on (11).
