Abstract
The utility model provides a distillation combining equipment of the high-purity phsophorus trichloride, comprising a quartz bottle body, a reflux condenser pipe, an air duct, a liquid seal jar and a fractionating condensation tube, wherein the quartz bottle body is connected with the liquid seal jar; the liquid seal jar is connected with one end of the reflux condenser pipe; the other end of the reflux condenser pipe is connected with one end of the air duct; the other end of the air duct is connected with the liquid seal jar; and the liquid seal jar is connected with one end of the a fractionating condensation tube. The utility model employs the two-stage condensation structure and has high recovery ratio of the high-purity phsophorus trichloride and strong stability.
Description
Technical field
The utility model belongs to meticulous technical field of phosphorous chemical industry, particularly a kind of distillation clustered aggregates of high-purity phosphorus trichloride.
Background technology
The domestic phosphorus trichloride distillatory clustered aggregates that is generally used for, the main clustered aggregates that adopts exit end and spherical condensation tube by quartzy bottle to be formed by connecting.During this equipment used, its efficient that reclaims phosphorus trichloride was low, poor stability.
Summary of the invention
The purpose of this utility model, be to be used for high-purity phosphorus trichloride distillatory clustered aggregates and to use in conjunction with above-mentioned, the rate of recovery of its high-purity phosphorus trichloride is low, and the problem of poor stability, provide a kind of under normal temperature, condition of normal pressure, rate of recovery height, and the distillation clustered aggregates of the strong high-purity phosphorus trichloride of stability.
The distillation clustered aggregates of high-purity phosphorus trichloride of the present utility model, by quartzy bottle, reflux condensing tube, airway, liquid seal can, condensate fractionation tube apparatus through combining.Its quartzy bottle is connected with liquid seal can, and liquid seal can is connected with an end of reflux condensing tube, and the other end of reflux condensing tube is connected with an end of airway, and the other end of airway is connected with liquid seal can, and liquid seal can is connected with an end of condensate fractionation pipe.
The following end interface of quartzy bottle is connected with the left end interface of liquid seal can, the hub-interface of liquid seal can is connected with the following end interface of reflux condensing tube, the last end interface of reflux condensing tube is connected with the last end interface of airway, the following end interface of airway is connected with the right-hand member interface of liquid seal can, and the following end interface of liquid seal can is connected with the last end interface of condensate fractionation pipe.
After the distillation clustered aggregates operation of high-purity phosphorus trichloride of the present utility model, owing to adopt the two-stage condensation structure, the rate of recovery height of its high-purity phosphorus trichloride, and stability is strong.

Embodiment
Below in conjunction with above-mentioned accompanying drawing example, the distillation clustered aggregates of high-purity phosphorus trichloride of the present utility model is made further enumeration.The example of distillation clustered aggregates of the present utility model comprises quartzy bottle 15, reflux condensing tube 5, airway 8, liquid seal can 1, condensate fractionation pipe 13.Its quartzy bottle 15 is connected with liquid seal can 1, and liquid seal can 1 is connected with an end of reflux condensing tube 5, and the other end of reflux condensing tube 5 is connected with an end of airway 8, and the other end of airway 8 is connected with liquid seal can 1, and liquid seal can 1 is connected with an end of condensate fractionation pipe 13.
The last end interface 17 of quartzy bottle 15 is connected with thermometer, following end interface 16 is connected with the left end interface 2 of liquid seal can 1, the hub-interface 3 of liquid seal can 1 is connected with the following end interface 4 of reflux condensing tube 5, the last end interface 6 of reflux condensing tube 5 is connected with the last end interface 7 of airway 8, the following end interface 9 of airway 8 is connected with the right-hand member interface 10 of liquid seal can 1, the following end interface 11 of liquid seal can 1 is connected with the last end interface 12 of condensate fractionation pipe 13, and the following end interface 14 of condensate fractionation pipe 13 is connected with the product receiving flask.
After the distillation clustered aggregates operation of high-purity phosphorus trichloride of the present utility model, phosphorus trichloride is got its fraction of 74～76 ℃ and is got high-purity phosphorus trichloride in heat-processed.Liquid through reflux condensing tube 5 cooling for reflux is collected in the liquid seal can 1, and the gas that does not reflux is isolated by liquid seal can 1, and after airway 8 was sent into 13 coolings of condensate fractionation pipe, the following end interface 14 through condensate fractionation pipe 13 flowed in the product receiving flask again.
