Abstract
The utility model relates to a reflux condenser which comprises a main body pipe and a condenser pipe, wherein the main body pipe is provided with an outer ground connector and an inner ground connector and the condenser pipe is installed in the main body pipe. The reflux condenser is characterized in that a T-shaped three-way piston is respectively connected with the outer ground connector and the main body pipe and the upper end of the outer ground connector in the main body pipe is connected with an intercepting pipe. The reflux condenser has the advantages of having simple structure, convenient operation and low production cost, and being capable of effectively integrating the functions of reflux, reactive solvent amount control and distillation.
Description
One, technical field
The utility model relates to a kind of reflux condenser, relates in particular to a kind of reflux condenser that can be advantageously used in solvent seasoning, synthetic reaction backflow, the control of reaction dissolvent amount or reaction back separated in the organic synthesis laboratory respectively.
Two, background technology
Backflow is in the organic synthesis process, for reaction being taken place as early as possible or finish, by reflux condenser and control heating, makes reaction temperature reach maximization and a operation usually that solvent does not lose; Distillation then is after reaction finishes, according to the difference of solvent, reactant or product boiling point, by distilling apparatus and the mode of controlling heating and cooling with its a kind of common operation that separates; These operations all are to use different glass apparatus to carry out respectively in the existing organic synthesis laboratory, promptly load onto reflux condenser and carry out reflux operation on many mouthfuls of reaction bulbs; Present reflux condenser comprises main body pipe and condenser pipe, is provided with ground interface in an outer grinding port interface and on the main body pipe, and condenser pipe is installed in the main body pipe; This reflux operation can not be controlled quantity of solvent, and before reaction, the interpolation of reaction dissolvent is mostly can just the solubilizing reaction thing being suitable, to reach the maximum likelihood of molecular collision; When reaction was in backflow, owing to organic solubility can increase along with the rising of temperature, it is excessive that reaction dissolvent just becomes; Present reaction unit all uses simple reflux condenser, does not all have to consider and can not address this problem; In addition, after reaction finishes, as the need distillation procedure, then will remove reflux condenser, install distilling apparatus again, carry out distillation procedure, the more glass apparatus of action need so respectively, takes equipment at its working costs, effort.
Three, summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to provide a kind of simple in structure, easy to operate, low function collection reflux condenser all over the body that also can will reflux effectively, control reaction dissolvent amount and distillation of production cost.
Technology contents of the present utility model is, a kind of reflux condenser comprises main body pipe and condenser pipe, is provided with ground interface in an outer grinding port interface and on the main body pipe, and condenser pipe is installed in the main body pipe; It is characterized in that a T stop,threeway is connected with the main body pipe with the outer grinding port interface respectively, the outer grinding port interface upper end in the main body pipe is connected with one and holds back pipe.
Technical characterictic of the present utility model is that the function with control of reflux condensation mode, reaction dissolvent and distillation combines, and finishes with a glass apparatus; Wherein the effect of solvent still head is not only played in blanking tube and T threeway in last handling process, also in course of reaction, plays the effect of control reaction dissolvent amount.
The utility model also can be used for the drying backflow of solvent and collects, and is equivalent to solvent still head and reflux condenser and unites use; Because joint is less, it is less to take up space, easy to use, and sealing effectiveness is better; In particular for the drying processing of solvent in a small amount, this device is extremely practical; When the drying that is used for relatively large solvent is handled, with main body control globulate, and at main body Guan Shangshe one sample tap.
The advantage that the utility model compared with prior art has is:
1, the utility model can be effectively will reflux, control reaction dissolvent amount and distillation collection all over the body, compact conformation, make simplify, production cost is lower.
2, the utility model is easy to operate, saves time, laborsaving, province's equipment.
3, the utility model can freely be controlled the actual use amount of reaction dissolvent, can shorten the reaction time effectively and improve reaction yield.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Five, the specific embodiment
As shown in Figure 1, a kind of reflux condenser comprises main body pipe 1 and condenser pipe 2, is provided with ground interface 4 in an outer grinding port interface 3 and on main body pipe 1, and condenser pipe 2 is installed in the main body pipe 1; It is characterized in that a T stop,threeway 5 is connected with main body pipe 1 with outer grinding port interface 3 respectively, outer grinding port interface 3 upper ends in main body pipe 1 are connected with one and hold back pipe 6.
The utility model is carrying out reflux operation: T stop,threeway 5 is only transferred to communicate with reaction system, allow the steam that produces rise by blanking tube 6, run into condenser pipe 2 and become liquid, turn back in the reaction system by T stop,threeway 5.
The utility model is carrying out the control operation of reaction dissolvent amount: T stop,threeway 5 is only transferred to position with contract fully, allow the steam that produces rise by blanking tube 6, run into condenser pipe 2 and become liquid, be kept at the bottom of blanking tube 6; Observing response solution when just by clear feculence, is then adjusted solvent that T threeway 5 makes the bottom that is kept at blanking tube 6 and is dripped and get back in the reaction solution, makes it become clear; Keep the optimum response quantity of solvent with the height of control reflux solvent afterwards in blanking tube 6 bottoms; This principle can according to circumstances be used flexibly and repeatedly.
The utility model is carrying out distillation procedure: T stop,threeway 5 is only transferred to communicate with the reception system, allow the steam that produces run into condenser pipe 2 and become liquid, flow in the reception system by T stop,threeway 5.
