The isomerization reactor frequency conversion device used for the synthetic camphor production system of utility model is formed by adding a set of frequency conversion member on the existing isomerization reactor structure against a factor of affecting the synthetic camphor quality principally, such that stirring speed may be regulated based on reaction condition to control produce of fenchene so as to improve quality of alcanfor products.
Description
Technical field
The utility model relates to a kind of converter plant, particularly a kind of isomerization reaction still converter plant that is used for the artificial camphor production system.
Background technology
Camphor is a kind of have skin irritatin class pharmaceutically active, anticorrosion activity, expelling parasite and anti-active product of damaging by worms.The basic standard of China's production and selling industry rank artificial camphor is artificial camphor standard GB/T 4895-2007 " artificial camphor ", and wherein, the content of camphor or camphanone-2 and isomers thereof is one of key technical index of weighing the artificial camphor quality.According to the study, in the turpentine oil isomerization process, have following reaction and produce simultaneously:
(1) firpene plays isomerization and becomes amphene, dipentene and other terpenes.
(2) dipentene further plays isomerization and becomes other monocycle terpenes: terpinolene and α-terpinene.
(3) the party effect also can take place in the terpenes of all participation effects, and under general condition, the di-terpene of production is more.
(4) when firpene plays isomerization reaction, form the fenchene of some, three kinds of fenchenes that structure is different are wherein arranged, i.e. α-fenchene, β fenchene and γ-fenchene.
The same easy the esterification with amphene of fenchene in the presence of organic acid, can generate different fennel seeds ester when handling with organic acid.When esterification material (amphene and fenchene) reached maximum, different fennel seeds ester was about 10% of all carboxylates
Fenchene generates different fennel seeds ester in the presence of organic acid, because the boiling point of different fennel seeds ester and Isobornyl is close, divide divorce fennel seeds ester just very difficult from Isobornyl.When saponification, different fennel seeds ester becomes different fenchanol, generates isofenchone through dehydrogenation again.Isofenchone is the isomers of very approximate camphor, 5～6 ℃ of its fusing points, 192～193 ℃ of boiling points.Isofenchone is mingled in the fusing point that can make camphor in the camphor to be reduced, thereby has reduced the quality of artificial camphor.This shows that isomerization reaction will reduce the generation fenchene as far as possible.
Can know relatively that from above analysis the factor that influences camphor quality maximum is a fenchene, produce so how control fenchene well in the isomery operation, be the key of the whole artificial camphor quality of influence.But with present technology is the generation to fenchene to control in the isomery operation.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part and provides a kind of fenchene of controlling to produce, and improves the isomerization reaction still converter plant that is used for the artificial camphor production system of artificial camphor quality.
The utility model is realized by following approach:
The isomerization reaction still converter plant that is used for the artificial camphor production system, wherein the isomerization reaction still includes isomery pot, sampler and agitating member, agitating member is installed on isomery pot inner chamber, its structural feature is, also include a converter plant, the agitating member in this converter plant and the isomerization reaction still is in transmission connection.
Its course of work is as follows: raw material enters the isomery pot after metering, through dehydration, carry out isomerization reaction after adding catalyst, in the process that adds catalyst and control reaction temperature, adopt converter plant control agitating member, thereby adjusting mixing speed, strict control side reaction produces the particularly generation of fenchene and tricyclene alkene.Like this, converter plant just can be regulated mixing speed by the control agitating member, thereby the generation of control fenchene has improved the artificial camphor quality greatly.
Above-mentioned converter plant can adopt commercially available frequency converter to carry out corresponding transformation and can use, because in this area, in isomerization reaction, require fixedly mixing speed, to guarantee the smooth isomerization reaction of artificial camphor, therefore those skilled in the art do not consider the application of converter plant on present technique for a long time, have just caused a kind of technology prejudice in the course of time.Technical staff of the present utility model has broken through this technology prejudice just, a large amount of experiments and detection have been carried out, drawn in the differential responses stage and adopted different mixing speeds, can reduce the generation of fenchene, improve the quality of artificial camphor, having unobviousness, is an innovation greatly of this area.
Above-mentioned sampler is to be used to take a sample the chromatogram check and analysis, except in adding the catalyst process, regulating mixing speed by converter plant, after the sampling chromatography, also need to regulate mixing speed, so the utility model can further be specially according to detected firpene content:
Also include an automaton, it is electrically connected with converter plant.
Automaton includes comparison means and standard apparatus, the firpene content of standard apparatus for setting, comparison means receives the actual firpene content that sampler draws, then with standard apparatus in the firpene value compare, when actual firpene content changes, comparison means just sends and drives signal to converter plant, drives the converter plant variable-frequency and variable-speed, thus the control mixing speed.
Above-mentioned adjusting is that a kind of trace in course of reaction is regulated, and according to great deal of experiment data as can be known, during medical use synthetic camphor more than producing the DAB-8 rank, mixing speed should change to some extent in each stage of material reaction:
Reaction mixing speed in early stage is controlled at 40r/min;
Reaction mixing speed in mid-term is controlled at 60r/min;
Reaction later stage mixing speed is controlled at 80r/min.
The fenchene content that can make reaction be produced like this is minimum.
In sum, the utility model provides a kind of isomerization reaction still converter plant that is used for the artificial camphor production system, be primarily aimed at the factor (fenchene) that influences the artificial camphor quality, on original isomerization reaction still structure, install a cover converter plant additional, can regulate mixing speed according to response situation, the generation of control fenchene, the quality of raising camphor product.
