Abstract
The utility model discloses a phosphorus trichloride reaction kettle with a reflux tube. The phosphorus trichloride reaction kettle comprises a phosphorus trichloride reaction kettle (1) and further comprises a reflux tube (2), wherein an outlet and a reflux port are formed in the phosphorus trichloride reaction kettle (1); and the outlet of the phosphorus trichloride reaction kettle (1) is communicated with the reflux port by virtue of the reflux tube (2). The phosphorus trichloride reaction kettle with the reflux tube has the advantages that chlorine gas is continuously guided to the reaction kettle by virtue of the reflux tube for reaction.
Description
Technical field
The present invention relates to chemical field, be specifically related to a kind of phosphorus trichloride reactor with return line.
Background technology
At present, when producing phosphorus trichloride, chlorine and liquid phosphorus need to be passed into reactor and react, and when the liquid phosphorus in reactor and chlorine reaction, some chlorine is located at the reactor inner and upper, can not fully react with liquid phosphorus.
Summary of the invention
Purpose of the present invention is exactly at present, when producing phosphorus trichloride, chlorine and liquid phosphorus need to be passed into reactor reacts, some chlorine can swim in the reactor upper strata can not enter reaction, cause waste, cause production cost too high, deficiency, and provide a kind of phosphorus trichloride reactor with return line.
The utility model comprises the phosphorus trichloride reactor, it is characterized in that it also has return line, and the phosphorus trichloride reactor is provided with outlet and refluxing opening, and the outlet of phosphorus trichloride reactor communicates with refluxing opening by return line.
The utility model has the advantages that: return line constantly again is directed into chlorine in reactor and reacts.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model comprises phosphorus trichloride reactor 1, it is characterized in that it also has return line 2, and phosphorus trichloride reactor 1 is provided with outlet and refluxing opening, and the outlet of phosphorus trichloride reactor 1 communicates with refluxing opening by return line 2.
Mode of operation: during reaction, first liquid phosphorus and chlorine are passed into respectively to phosphorus trichloride reactor 1 and react, the chlorine of failing to obtain fully reaction in reaction process enters to from return line 2 circulations and carries out in reactor fully that reaction gets final product.
Claims (1)
1. phosphorus trichloride reactor with return line, it comprises phosphorus trichloride reactor (1), it is characterized in that it also has return line (2), phosphorus trichloride reactor (1) is provided with outlet and refluxing opening, and the outlet of phosphorus trichloride reactor (1) communicates with refluxing opening by return line (2).
