Description
Technical field
The present invention relates to a kind of continuous production device synthesized to isobutyryl chloride.
Background technology
Fig. 1 is refer to, isobutyryl chloride is prepared as the production of interval metaplasia at present, to reach certain production scale, it is necessary to more
Kettle produces simultaneously.Intervalization is reacted, can not continuous production, Automated condtrol can not be realized, layering can thoroughly not increase follow-up place
Science and engineering sequence, raw material are not sufficiently reacted, and cause to waste.
The content of the invention
It is an object of the invention to provide a kind of continuous production device of isobutyryl chloride synthesis, how solution enters to isobutyryl chloride
Row quantity-produced technical problem.
The continuous production device of isobutyryl chloride synthesis, including isobutyric acid ingress pipe, first order reactor, the first order turn material
Pump, first order cooler, first order layering tower, phosphorous acid delivery line, phosphorus trichloride ingress pipe, second level reactor, the second level
Transfering material pump, second-stage cooler, substratification tower, isobutyryl chloride delivery line, circulating pump；Isobutyric acid ingress pipe, the first order are anti-
Kettle, first order transfering material pump, first order cooler is answered to be sequentially communicated to first order layering tower centre position；First order layering tower top
Connect second level reactor, first order layering tower bottom connection phosphorous acid delivery line；Second level reactor, second level transfering material pump,
Second-stage cooler is sequentially connected to substratification tower centre position；Substratification tower top end connection isobutyryl chloride export
Pipe, bottom connection circulating pump, the circulating pump also connect with first order reactor；Phosphorus trichloride is also communicated with the reactor of the second level
Ingress pipe.
A flow valve is respectively provided with the isobutyric acid ingress pipe and phosphorus trichloride ingress pipe.
The beneficial effects of the invention are as follows：The present apparatus first imports excessive isobutyric acid, such isobutyric acid in isobutyric acid ingress pipe
Generation isobutyric acid, isobutyryl chloride and phosphorous acid are reacted in first order reactor with phosphorus trichloride；These three materials are through supercooling
After device and layering tower separation, the phosphorous acid delivery line of phosphorous acid from layering tower bottom carries out refining treatment；Isobutyric acid, isobutyryl chloride
Enter in the reactor of the second level, excessive phosphorus trichloride is at this moment passed through in the reactor of the second level, at this moment in second level reactor
Interior to generate isobutyryl chloride, intermediate, phosphorous acid, these materials are also mixed with remaining phosphorus trichloride simultaneously；At this moment by these
Material is sent into substratification tower, and isobutyryl chloride just flows out at the top of layering tower and goes rectifying to carry from the export of isobutyryl chloride delivery line
Refining；Remaining intermediate, phosphorous acid, phosphorus trichloride enter isobutyl acid reaction in first order reactor and excessive, so follow
Ring goes down to be produced to isobutyryl chloride.

Embodiment
It refer to Fig. 2, the continuous production device of the isobutyryl chloride synthesis in figure, including an isobutyric acid ingress pipe 1, one
4, one, the first order cooler phosphorous of first order layering tower 5, one of first order transfering material pump 3, one of first order reactor 2, one
The sour phosphorus trichloride ingress pipe 7, one of delivery line 6, one second level transfering material pump 9, one of second level reactor 8, one second level
It is 10, one, cooler, 11, one, substratification tower isobutyryl chloride delivery line, 12, circulating pumps 13, multiple to the said equipment
The pipeline 14 connected.
Isobutyric acid ingress pipe 1 is used to the isobutyric acid of excess importeding into the first reactor 2, and first order reactor 2 is used for
Excessive isobutyric acid reacts with a small amount of phosphorus trichloride；First order transfering material pump 3 is used for reacted material in the first reactor 2
First layer tower 5 is imported into through first order cooler 4 so to reclaim phosphorous acid and import isobutyric acid and isobutyryl chloride
Reacted in second level reactor 8 with excessive phosphorus trichloride, after the material reaction in second level reactor 8, the second level turns
The material of generation is imported into substratification tower 11 by material pump 9 after second-stage cooler 10 cools down, substratification tower 11
Top just isobutyryl chloride is exported from isobutyryl chloride delivery line 12, remaining phosphorous acid, intermediate, phosphorus trichloride are just by circulating
Pump 13 is imported into first order reactor 2 again, is at this moment just passed through excessive isobutyric acid again, so circular response successively.For
Material derived from isobutyric acid ingress pipe 2 and phosphorus trichloride ingress pipe 7 is controlled, stream is installed on corresponding ingress pipe
Measure valve 15.
The equipment of the present embodiment uses isobutyric acid and phosphorus trichloride when reacting beginning that one of which material is excessive, and band is instead
Ying Houzai is excessive by another material, is achieved in that the continuous production of isobutyryl chloride.
