Abstract
The utility model discloses a process units of preparation trimethyl borate, including reactor, crude steam kettle, reaction rectifying column with add the salt extraction rectifying column, the reactor communicates with each other through pipeline and crude steam kettle, and the crude steam kettle communicates with each other through pipeline and reaction rectifying column, the reaction rectifying column through the pipeline with add the salt extraction rectifying column and communicate with each other. The utility model discloses a process units of preparation trimethyl borate, the low advantage low with the energy consumption of equipment investment can improve separation efficiency, has gained better technological effect, and the result yield is high, and purity is high, has fine practicality.
Description
Technical field
The utility model relates to organism Preparation equipment technical field, is specifically related to a kind of process unit preparing trimethyl borate.
Background technology
The existing process unit preparing 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 continuous production of end product 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 process unit preparing trimethyl borate, has facility investment low, the features such as good separating effect.
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 process unit preparing trimethyl borate, comprise reactor, crude steam kettle, reactive distillation column and Salt Addition Extraction Refinery Tower, reactor is communicated with crude steam kettle by pipeline, and crude steam kettle is communicated with reactive distillation column by pipeline, and reactive distillation column is communicated with Salt Addition Extraction Refinery Tower by pipeline.
Described reactor establishes feed(raw material)inlet.
Beneficial effect: compared with prior art, the process unit preparing trimethyl borate of the present utility model, the advantage that facility investment is low and energy consumption is low, can improve separation efficiency, achieve good technique effect, efficiency of pcr product is high, purity is high, has good practicality.
Accompanying drawing explanation
Fig. 1 is the structural representation of the process unit preparing trimethyl borate.
Embodiment
Below in conjunction with specific embodiment, the utility model is described further.
As shown in Figure 1, prepare the process unit of trimethyl borate, comprise reactor 1, crude steam kettle 2, reactive distillation column 3 and Salt Addition Extraction Refinery Tower 4, 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, and reactive distillation column 3 is communicated with Salt Addition Extraction Refinery Tower 4 by pipeline.
During use, methyl alcohol and boric acid are added in reactor 1, carry out initial reaction, then enter crude steam kettle 2 to 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, control design temperature and flow, carry out extractive distillation with salt, obtain end product trimethyl borate.
This prepares the process unit of trimethyl borate, and the advantage that facility investment is low and energy consumption is low, can improve separation efficiency, achieve good technique effect.
