The reaction unit is characterized in that a membrane separator (3) is arranged between the distillation column (4) and the reaction column (2). According to the reaction unit disclosed by the utility model, the membrane separator (3) is arranged at the front of the distillation column (4), so that the content of the isoborneol in reaction liquid can be increased, the amount of distillation reaction liquid of the distillation column (4) is reduced; and therefore, a large amount of energy sources are saved and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of chemical reaction device, relates in particular to a kind of reaction unit of amphene hydration isocamphol.
Background technology
Prepare the gordian technique that isocamphol is artificial camphor from amphene, in the prior art, adopt hydration resin to carry out hydration reaction as catalyzer with single stage method amphene hydration isocamphol, reacted aqua liquid is through after flash distillation, concentrating, and centrifugation obtains isocamphol.Because in the prior art, the content (content is in 10%) on the low side in aqua liquid of single stage method down alkene hydration isocamphol reaction back isocamphol, therefore, concentrating aqua liquid needs a large amount of energy to carry out, flash distillation to required concentrated solution, therefore, the cost of artificial camphor is high, has restricted the industrial application that its single stage method amphene hydration isocamphol is produced.
Summary of the invention
The utility model provides a kind of reaction unit of amphene hydration isocamphol at existing issue, can significantly reduce the amount of existing distilled and concentrated solution, saves a large amount of energy, reduces the cost of artificial camphor.
The utility model is realized by following scheme: a kind of reaction unit of amphene hydration isocamphol, formed by blend tank, reaction column, distillation tower, condenser, well heater, storage tank, centrifuge separator, recycle pump, the bottom of blend tank and reaction column is connected, have condenser, storage tank, recycle pump and blend tank pipe connection at the distillation tower cat head, and connected centrifuge separator at the bottom of the distillation Tata, it is characterized in that: between distillation tower and reaction column, be provided with a membrane separation apparatus.
Further, described membrane separation apparatus is characterized in that adopting nanofiltration membrane.
Further, described membrane separation apparatus is characterized in that the nanofiltration membrane that adopts is nanofiltration membrane.
The utility model is achieved in that in blend tank, deployed amphene by a certain percentage, Virahol, deionized water, deployed mixed solution enters reaction column from the bottom, in reaction column, fill hydration resin, mixed solution is under the katalysis of hydration resin, amphene and water generation hydration reaction generate isocamphol and a spot of by-product oil, after reaction, reaction solution flows out on the top of reaction column and enters into the membrane separation apparatus separation, unreacted amphene, water and solvent Virahol are because molecular weight is less, can pass through nanofiltration membrane, flow out to separate and circulate from the side of membrane separation apparatus and enter into blend tank and continue to use, and the isocamphol molecular weight in the reaction solution more greatly can not be by the nanofiltration membrane in the membrane separation apparatus, the solvent Virahol that isocamphol is carried secretly, and the part amphene that is dissolved in the Virahol is then entering into distillation tower with isocamphol through the membrane separation apparatus pipeline, reaction solution is through behind the membrane separation apparatus, reaction solution is concentrated, improved the wherein content of isocamphol, in distillation tower, reaction solution can further be concentrated, the overhead product that cat head obtains is through condenser, storage tank, recycle pump, reenter in the blend tank, and the concentrated solution that comes out at the bottom of the tower is separated the isocamphol of crystallization and the by-product oil of hydration reaction generation through centrifuge separator.
The utility model can improve the isocamphol content in the reaction solution owing to increased membrane separation apparatus before distillation tower, has reduced the amount of distillation tower distillation reaction liquid, thereby has saved a large amount of energy, has reduced its production cost.
