Background technology
Existing is that traditional reaction unit of raw material synthesizing dihydromyrcenol is to adopt fixed-bed reactor with the dihydromyrcene, mainly is made up of component such as evaporating kettle, gas cylinder, condenser, fixed beds.Adopting this fixed-bed reactor is that reaction raw materials dihydromyrcene, water, solvent once are added evaporating kettle, make the material evaporation by constantly heating continuously, after condenser condenses, the hydration reaction that circulates of the catalyst layer in the fixed bed of flowing through generates dihydromyrcenol.This fixed-bed reactor exist and reaction product dihydromyrcenol and raw material can not be separated continuously the outer shortcoming of back discharge evaporating kettle, like this owing to the time of hydration reaction needs is long, the product dihydromyrcenol that reaction generates can only be for a long time and raw material mix and rest in the evaporating kettle, cause dihydromyrcenol long heat-up time, side reactions such as cyclodehydration, isomerization take place easily, have reduced the product yield, product fragrance is also bad.
The utility model content
The purpose of this utility model provides a kind of rectifying-reaction serialization and prepares the device of dihydromyrcenol, it can carry out the building-up reactions operation of serialization, the product dihydromyrcenol is continuously separated from reaction system, reduce its heated time, avoid taking place too much side reaction, improve the product yield, make product fragrance better.
The utility model is achieved through the following technical solutions above-mentioned purpose: a kind of rectifying-reaction serialization prepares the device of dihydromyrcenol, comprise the tower still, condenser, fixed bed, the built-in heating coil of tower still, the built-in catalyst layer of fixed bed, described tower still top is provided with body of the tower, described body of the tower is built-in with reflux splitter, stainless steel ripple filler and heating coil, the mixed pot bottom outlet of raw material links to each other with the preheater import, the preheater outlet links to each other with the import of body of the tower epimere reflux splitter, the outlet at bottom of tower still links to each other with cooler inlet, cooler outlet links to each other with the import of product tank top, the top of tower still links to each other with the body of the tower bottom, the body of the tower top links to each other with the condenser bottom inlet, the condenser outlet at bottom links to each other with the fixed bed top inlet, and the fixed bed outlet at bottom links to each other with the import of body of the tower hypomere reflux splitter.
Described body of the tower is divided into upper and lower two sections, and epimere is built-in with epimere reflux splitter, epimere stainless steel ripple filler and epimere heating coil, and hypomere is built-in with hypomere reflux splitter, hypomere stainless steel ripple filler and hypomere heating coil.
The built-in spiral coil cooling tube of described product storage tank.
The use principle and the process of this device are as follows: with dihydromyrcene, water, solvent adds the mixed pot of raw material by a certain percentage, stir, after the preheater preheating, continuously add in the tower from the import of body of the tower epimere reflux splitter by certain flow, open the built-in heating coil heating of body of the tower and tower still, make the three form the azeotrope evaporation, after condenser condenses, the catalyst layer in the fixed bed of flowing through carries out hydration reaction and generates dihydromyrcenol, pass back in the tower by the import of body of the tower hypomere reflux splitter then, fractionation by the built-in stainless steel ripple filler of body of the tower, continuously will react the product dihydromyrcenol that generates and unreacted completely raw material separate, dihydromyrcenol continuously enters the product storage tank by certain flow through supercooler through tower still discharge port, it is standby to carry out cooling preservation, raw material is then after condenser condenses completely for unreacted, and the catalyst layer in the fixed bed of continuously flowing through is proceeded the hydration reaction that circulates.
Compared with prior art, the utlity model has following advantage:
1, the operation of serialization can be carried out to building-up reactions, improved production efficiency, and conventional apparatus periodical operation can only be carried out.
2, the product dihydromyrcenol that produces in the hydration reaction process continuously can be separated from reaction system, the shortcoming of having avoided traditional reaction unit dihydromyrcenol can't be separated, reduced the time that product is heated, avoid dihydromyrcenol that side reactions such as cyclodehydration, isomerization take place too much, improved the product yield, made product fragrance better.
