Abstract
The utility model discloses an anisic aldehyde production line. The production line comprises a reaction kettle and a rectifying tower, wherein a pressure filtration device, a crude anisic aldehyde separation device and a neutralizing treatment device are arranged between the reaction kettle and the rectifying tower; the reaction kettle is connected with the pressure filtration device through a pipeline; the pressure filtration device is connected with the crude anisic aldehyde separation device through a pipeline; the crude anisic aldehyde separation device is connected with the neutralizing treatment device through a pipeline; and the neutralizing treatment device is connected with the rectifying tower through a pipeline. Compared with the prior art, the utility model has the advantages that as the special packed rectifying tower is adopted, the separation effect is good, the aroma of anisic aldehyde produced in the production line is pure, the anisic aldehyde purity is higher than 98 percent, and the crude scale can be higher than 95 percent; and by adopting the production line, the productivity of anisic aldehyde produced through anise camphor can reach 65 to 68 percent.
Description
Technical field
The utility model relates to a kind of production line of natural perfume, is specifically related to a kind of production line that is prepared anisyl aldehyde by the isoesdragol oxidation.
Background technology
Anisyl aldehyde claims aubepine again, and chemical name is an aubepine, and molecular formula is C
8H
8O
2Pure product are colourless to weak yellow liquid.Because of aubepine has persistent hawthorn fragrance, the fragrant tempting multiple essence such as sweet floral type, cloves type and hawthorn odor type that are widely used in preparing, be used for the preparation of food, carbohydrate and beverage class essence; Aspect organic intermediate, it is the intermediate of preparation medicine Porphyrin-Based Sensitizer, vasodilator, oxyammonia card base penicillin etc.; On agricultural, can be used as sterilant, biological growth inhibitor etc.Aubepine can be made through oxidation by methyl allylphenol, but the productive rate of traditional trans-anethole oxidation production line has only about 60%.
The utility model content
The technical problems to be solved in the utility model provides a kind of anisyl aldehyde production line.Adopt this production line can reach 65～68% with the productive rate that isoesdragol prepares anisyl aldehyde.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anisyl aldehyde production line, comprise reactor and rectifying tower, between reactor and rectifying tower, be provided with filter-pressing device, anisyl aldehyde crude product tripping device and neutralizing treatment device, between described reactor and the filter-pressing device, between filter-pressing device and the anisyl aldehyde crude product tripping device, between anisyl aldehyde crude product tripping device and the neutralizing treatment device and between neutralizing treatment device and the rectifying tower by pipe connection.
In the technique scheme:
Described filter-pressing device is a pressure-filtering tank.
Described anisyl aldehyde crude product tripping device is for dividing flow container.
Described neutralizing treatment device is an open container, also can be a retort.
Described rectifying tower is a stuffing rectification column.
The conveying of intermediates can also be provided with transferpump on each pipeline path for convenience.
Compared with prior art, advantage of the present utility model is: adopt special stuffing rectification column, good separating effect, the anisyl aldehyde fragrance that obtains is pure, purity reaches more than 98%, natural Du Keda is more than 95%, and adopts this production line can reach 65～68% with the productive rate that isoesdragol prepares anisyl aldehyde.
Description of drawings
Fig. 1 is the schematic flow sheet of a kind of embodiment of this novel anisyl aldehyde production line.
Number in the figure is:
1, reactor; 2, pressure-filtering tank; 3, divide flow container; 4, neutralization tank; 5, stuffing rectification column.
Embodiment
In embodiment shown in Figure 1, a kind of anisyl aldehyde production line of the utility model, comprise reactor 1 and stuffing rectification column 5, between reactor 1 and stuffing rectification column 5, be provided with pressure-filtering tank 2 successively, divide flow container 3 and neutralization tank 4, described reactor 1 and pressure-filtering tank 2, pressure-filtering tank 2 and divide between the flow container 3, divide between flow container 3 and neutralization tank 4 and neutralization tank 4 and the stuffing rectification column 5 by pipe connection.
During concrete production, isoesdragol, dilute sulphuric acid and oxygenant are put into reactor 1 according to a certain percentage, at a certain temperature reaction.Reaction is put into pressure-filtering tank 2 while hot with reaction mass and is carried out press filtration after finishing, and filtrate is discharged at the bottom of jar, and filter residue takes out from tank deck.The filtrate of discharging from pressure-filtering tank 2 bottoms enters standing demix the branch flow container 3, and intermediates anisyl aldehyde crude product is discharged from minute flow container 3 bottoms and entered neutralization tank 4.Because sulfuric acid presents acidity because of containing partly in the gained anisyl aldehyde crude product, be neutral with soda ash regulator solution pH value, it is slightly oily behind standing demix the aubepine discharge promptly to be got aubepine.Carry out rectifying in the thick oily suction fractionate of gained aubepine, from cat head extraction aubepine product, through packing warehouse-in after the assay was approved, underproof product then drops into stuffing rectification column 5 once more and carries out heavily rectifying.
