Abstract
The invention discloses a process device for preparing trimethyl borate. The process device comprises a reactor, a rough steaming kettle, reactive distillation column and a salt-adding extractive distillation column, wherein the reactor communicates with the rough steaming kettle through a pipeline; the rough steaming kettle communicates with the reactive distillation column through a pipeline; the reactive distillation column communicates with the salt-adding extractive distillation column through a pipeline. The process device for preparing the trimethyl borate has the advantages of low equipment investment and low energy consumption, the separation efficiency can be increased, a good technical effect is achieved, and a product has high yield, high purity and high practicability.
Description
Technical field
The present invention relates to organic matter Preparation equipment technical field, and in particular to a kind of process unit for preparing trimethylborate.
Background technology
The existing process unit for preparing trimethylborate is normally only used in conjunction to prepare using reactor and rectifying column, it is azeotropic mixture of the trimethylborate with methyl alcohol that this device is finally obtained, need just obtain end-product trimethylborate after separating, the continuous preparation of end-product can not be realized, therefore use demand can't be fully met.
The content of the invention
Goal of the invention：It is low with equipment investment it is an object of the invention to provide a kind of process unit for preparing trimethylborate for the deficiencies in the prior art, the features such as good separating effect.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted by the present invention is as follows：
A kind of process unit for preparing trimethylborate, including reactor, crude steam kettle, reactive distillation column and Salt Addition Extraction Refinery Tower, reactor is communicated by pipeline with crude steam kettle, and crude steam kettle is communicated by pipeline with reactive distillation column, and reactive distillation column is communicated by pipeline with Salt Addition Extraction Refinery Tower.
Feed(raw material)inlet is set on the reactor.
Beneficial effect：Compared with prior art, the process unit for preparing trimethylborate of the invention, equipment investment is low and the low advantage of energy consumption, can improve separative efficiency, achieves preferable technique effect, and efficiency of pcr product is high, and purity is high, with good practicality.
Brief description of the drawings
Fig. 1 is the structural representation of the process unit for preparing trimethylborate.
Specific embodiment
With reference to specific embodiment, the present invention is described further.
As shown in Figure 1, prepare the process unit of trimethylborate, including reactor 1, crude steam kettle 2, reactive distillation column 3 and Salt Addition Extraction Refinery Tower 4, feed(raw material)inlet is set on reactor 1, reactor 1 is communicated by pipeline with crude steam kettle 2, crude steam kettle 2 is communicated by pipeline with reactive distillation column 3, and reactive distillation column 3 is communicated by pipeline with Salt Addition Extraction Refinery Tower 4.
When using, by in methyl alcohol and boric acid addition reactor 1, carry out initial reaction, it is evaporated subsequently into crude steam kettle 2, subsequently entering reactive distillation column 3 carries out rectifying, obtains the azeotropic mixture of trimethylborate and methyl alcohol, salt solvent and azeotropic mixture will be added to be separately added into extractive distillation column 4, control design temperature and flow, carry out extractive distillation with salt, obtain end-product trimethylborate.
This prepares the process unit of trimethylborate, and equipment investment is low and the low advantage of energy consumption, can improve separative efficiency, achieves preferable technique effect.
