Description
Technical field
The utility model relates to organism Preparation equipment technical field, is specifically related to a kind of continuous circulation preparation technology device of trimethyl borate.
Background technology
The continuous circulation preparation technology device of existing trimethyl borate generally only uses reactor and rectifying tower to be used in conjunction to prepare, it is the azeotrope of trimethyl borate and methyl alcohol that this device finally obtains, need just can obtain end product trimethyl borate after being separated, the recycling use of solvent can not be realized, therefore can't meet user demand completely.
Utility model content
Goal of the invention: for the deficiencies in the prior art, the purpose of this utility model is to provide a kind of continuous circulation preparation technology device of trimethyl borate, has facility investment low, good separating effect, the feature such as to recycle.
Technical scheme: in order to realize above-mentioned utility model object, the technical solution adopted in the utility model is as follows:
A kind of continuous circulation preparation technology device of trimethyl borate, comprise reactor, crude steam kettle, reactive distillation column, Salt Addition Extraction Refinery Tower and solvent recovery tower, reactor is communicated with crude steam kettle by pipeline, crude steam kettle is communicated with reactive distillation column by pipeline, reactive distillation column is communicated with Salt Addition Extraction Refinery Tower by pipeline, and Salt Addition Extraction Refinery Tower is communicated with solvent recovery tower by pipeline.
Described solvent recovery tower is communicated with Salt Addition Extraction Refinery Tower by solvent cycle pipeline.
Described reactor establishes feed(raw material)inlet.
Beneficial effect: compared with prior art, the continuous circulation preparation technology device of trimethyl borate of the present utility model, the advantage that facility investment is low and energy consumption is low, separation efficiency can be improved, achieve good technique effect, efficiency of pcr product is high, and purity is high, solvent can recycle, and has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the continuous circulation preparation technology device of trimethyl borate.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Figure 1, the continuous circulation preparation technology device of trimethyl borate, comprise reactor 1, crude steam kettle 2, reactive distillation column 3, Salt Addition Extraction Refinery Tower 4 and solvent recovery tower 5, reactor 1 establishes feed(raw material)inlet, reactor 1 is communicated with crude steam kettle 2 by pipeline, crude steam kettle 2 is communicated with reactive distillation column 3 by pipeline, reactive distillation column 3 is communicated with Salt Addition Extraction Refinery Tower 4 by pipeline, Salt Addition Extraction Refinery Tower 4 is communicated with solvent recovery tower 5 by pipeline, and solvent recovery tower 5 is communicated with Salt Addition Extraction Refinery Tower 4 by solvent cycle pipeline.
During use, methyl alcohol and boric acid are added in reactor 1, carry out initial reaction, then enter crude steam kettle 2 and evaporate, then enter reactive distillation column 3 and carry out rectifying, obtain the azeotrope of trimethyl borate and methyl alcohol, salt solvent will be added and azeotrope adds extractive distillation column 4 respectively, and control design temperature and flow, carry out extractive distillation with salt, bottom product passes into solvent recovery tower 5 and carries out solvent recuperation, and then circulation passes into extractive distillation column 4 and uses.
The continuous circulation preparation technology device of this trimethyl borate, the advantage that facility investment is low and energy consumption is low, can improve separation efficiency, achieve good technique effect.
