Abstract
The invention discloses a kind of catalyst and its applications for synthesizing prothioconazoles intermediate, by nickel acetylacetonate, four water cobalt acetates, polyvinylpyrrolidone, terephthalic acid (TPA) is put into the N of water sum, in N dimethyl formamide mixed solutions, magnetic agitation, it transfers the solution into the dynamic response kettle equipped with polytetrafluoroethyllining lining, dynamic response kettle is sealed, the organic inorganic composite materials of nickel cobalt are obtained by the reaction, wait for that reaction is cooled to room temperature, by product deionized water with N, N dimethyl formamide cross washings, it is dried in baking oven for 24 hours, the yellowish powdered organic inorganic composite materials of nickel cobalt are obtained with NaH2PO2The two in tube furnace is placed on together to separate using silica wool, under Ar protections, the nanoscale nickel cobalt bimetallic catalyst by the product utilization deionized water obtained after phosphatization with being dried to obtain black in absolute ethyl alcohol cross washing baking oven.Nickel cobalt bimetallic catalyst of the present invention increases substantially prothioconazoles intermediate yield, the technological process of production, reduces energy consumption.
Description
Technical field
The present invention relates to a kind of catalyst and its applications for synthesizing prothioconazoles intermediate, belong to catalysis technique neck
Domain.
Background technology
Prothioconazoles are worked by inhibiting the biosynthesis of mycosterol, have very extensive fungicidal spectrum.Rosickyite bacterium
Azoles interior suction is good, has excellent protection, treats and root out activity, the lasting period is long.Prothioconazoles not only have crop good
Safety, and preventing disease theraping effect is good, and volume increase is apparent.Compared with other triazole bactericidal agents, prothioconazoles more wide spectrum.Almost
To all wheat diseases have good control effect, as on wheat and barley powdery mildew, banded sclerotial blight, droop, leaf spot,
Rust, sclerotiniose, net blotch, moire disease etc.;The soil-borne disease of rape and peanut, such as sclerotiniose and main leaf can also be prevented
Face disease, such as gray mold, black spot, brown spot, balck shank, sclerotiniose and rust.But current prothioconazoles are produced
There is also many deficiencies from the point of view of method:Such as production process route complexity, the production cycle is long, causes producing cost excessively high;It prepared
Impurity is introduced in journey, and quality is caused to decline;If carrying out secondary crystallization, and operating cost is caused to increase, yield declines, and cost increases
1- (1- chlorine cyclopropyl) -2-(1,2,4- triazolyl) ethyl ketone be it is a kind of synthesis prothioconazoles important intermediate, improve its yield,
It is of great significance for shortening the prothioconazoles technological process of production, reducing energy consumption, finds a kind of raising 1- (1- chlorine cyclopropyl)-
2-(1,2,4- triazolyls) ethyl ketone synthetic yield catalyst and synthesis condition have very important significance.
Invention content
The purpose of the present invention is to provide a kind of catalyst and its application for synthesizing prothioconazoles intermediate, catalyst
Prothioconazoles intermediate 1,2,4- triazoles can be catalyzed well with optimal conditions and the chloro- 1- chloracetyls cyclopropane of 1- is anti-
It answers, there is higher product yield.
A kind of catalyst for synthesizing prothioconazoles intermediate, the catalyst are nickel cobalt bimetallic catalyst.
The nickel cobalt bimetallic catalyst preparation method is as follows:
Step 1, by 100mg nickel acetylacetonates, tetra- water cobalt acetates of 100mg, 400mg polyvinylpyrrolidones, 50mg terephthaldehydes
Acid is put into 80ml water and the N of 160ml, N dimethyl formamide mixed solution, magnetic agitation 20min, is uniformly mixed;
Above-mentioned solution is transferred in the dynamic response kettle equipped with polytetrafluoroethyllining lining by step 2, and dynamic response kettle is sealed
It is good, 6h is reacted at a temperature of 150 DEG C, obtains the organic inorganic composite materials of nickel cobalt, waits for that reaction is cooled to room temperature, product is spent
Ionized water with N, N dimethyl formamides cross washing 3 times, in 7400r/min centrifugations, 60 DEG C of baking ovens it is dry for 24 hours, obtain micro- Huang
The organic inorganic composite materials of powdered nickel cobalt of color;
Step 3, by the organic inorganic composite materials of the nickel cobalt obtained after drying with NaH2PO2It is placed in tube furnace together, with
The mass ratio of the organic inorganic composite materials of nickel cobalt is 5:1, the two is separated using silica wool, under Ar protections, from 20 DEG C of room temperature
Lower heating, heating rate are 2 DEG C/min, and reacting 3h at 350 DEG C just obtains product;
Step 4 centrifuges the product utilization deionized water obtained after phosphatization with absolute ethyl alcohol cross washing 5 times, 8500r/min
The nanoscale nickel cobalt bimetallic catalyst of black is dried to obtain in 6min, 60 DEG C of baking ovens.
Application of the catalyst in synthesis prothioconazoles intermediate.
The prothioconazoles intermediate is 1- (1- chlorine cyclopropyl) -2-(1,2,4- triazolyls) ethyl ketone.
Specific synthesis application is as follows:
