Description
Technical field
The present invention relates to organic matter Preparation equipment technical field, and in particular to a kind of continuous circulation preparation technology device of trimethylborate.
Background technology
The continuous circulation preparation technology device of existing 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 recycling use of solvent can not be realized, therefore use demand can't be fully met.
The content of the invention
Goal of the invention：For the deficiencies in the prior art, it is an object of the invention to provide a kind of continuous circulation preparation technology device of trimethylborate, good separating effect low with equipment investment, the features such as recycling.
Technical scheme：In order to realize foregoing invention purpose, the technical solution adopted by the present invention is as follows：
A kind of continuous circulation preparation technology device of trimethylborate, including reactor, crude steam kettle, reactive distillation column, Salt Addition Extraction Refinery Tower and solvent recovery tower, reactor is communicated by pipeline with crude steam kettle, crude steam kettle is communicated by pipeline with reactive distillation column, reactive distillation column is communicated by pipeline with Salt Addition Extraction Refinery Tower, and Salt Addition Extraction Refinery Tower is communicated by pipeline with solvent recovery tower.
The solvent recovery tower is communicated by solvent circulation line with Salt Addition Extraction Refinery Tower.
Feed(raw material)inlet is set on the reactor.
Beneficial effect：Compared with prior art, the continuous circulation preparation technology device of trimethylborate of the invention, equipment investment is low and the low advantage of energy consumption, separative efficiency can be improved, preferable technique effect is achieved, efficiency of pcr product is high, purity is high, and solvent can be recycled, with good practicality.
Brief description of the drawings
Fig. 1 is the structural representation of the continuous circulation preparation technology device of trimethylborate.
Specific embodiment
With reference to specific embodiment, the present invention is described further.
As shown in Figure 1, the continuous circulation preparation technology device of trimethylborate, including reactor 1, crude steam kettle 2, reactive distillation column 3, Salt Addition Extraction Refinery Tower 4 and solvent recovery tower 5, 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, reactive distillation column 3 is communicated by pipeline with Salt Addition Extraction Refinery Tower 4, Salt Addition Extraction Refinery Tower 4 is communicated by pipeline with solvent recovery tower 5, and solvent recovery tower 5 is communicated by solvent circulation line with Salt Addition Extraction Refinery Tower 4.
When using, by in methyl alcohol and boric acid addition reactor 1, initial reaction is carried out, is evaporated subsequently into crude steam kettle 2, subsequently entering reactive distillation column 3 carries out rectifying, obtain 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, tower bottom product is passed through solvent recovery tower 5 and carries out solvent recovery, and then circulation is passed through the use of extractive distillation column 4.
The continuous circulation preparation technology device of the trimethylborate, equipment investment is low and the low advantage of energy consumption, can improve separative efficiency, achieves preferable technique effect.
