Description
Technical field
The invention belongs to chemical industry catalysis technical fields, prepare quinoline more particularly to a kind of propenal aldehyde acetal/aniline reaction
Catalyst of derivative and preparation method thereof.
Background technique
Quinolines are a kind of extremely important nitrogen-containing heterocycle compounds, they synthetic dyestuffs, pesticide, medicine,
The chemical fields such as antioxidant, extractant, feed addictive and corrosion inhibiter have very extensive application.Especially in recent years, generation
It is developed in boundary many with quinolines newtype drug as main component, such as antitumor class, antimalarial class, treatment asthma
The drugs such as class, antibacterial anti-inflammatory class and hypertension class；In addition, quinolines can synthesize acid dyes Huang 3 and directly Huang
Equal welds, and niacin is obtained by oxidation reaction；And quinolines, which can also be used in preparation, has uniqueness electrically
It can such as be made by 8-hydroxyquinoline and fatty acid molysite with nanostructure/meso-hole structure organic functional material of optical property
For at sensible heat material.
Currently, being industrially to produce quinolines using chemical synthesis route；The synthesis road to have grown up
Line mainly includes liquid phase synthesizing method and gas phase synthesis method.Liquid phase synthesizing method mainly has: 1) Skraup method: this method be earliest exploitation and
Using most permanent method, be aniline, glycerol and oxidant (such as ferric trichloride, nitrobenzene or diarsenic pentoxide) are placed in it is dense
Heating is reacted to obtain quinoline jointly in sulfuric acid；But the strong acid corrosivity that the method is long there are reaction time, energy consumption is high, uses it is strong and
The problems such as serious pollution environment, it is difficult to for being mass produced；2) Doebner-Von Miller method: the method is by arylamine and aldehyde
Class/α, beta-unsaturated aldehyde carry out heating reaction under oxidant and acid condition and generate corresponding substituted quinoline derivatives,
Such as 4- methylquinoline and 2- phenyl -4- carboxyl quinoline；3) Conrad-Limpach method: the method is mainly by arylamine and 'beta '-ketoester
The synthesis of quinoline class compound under acid catalysis and heating condition；4) Combes method: the method is mainly by arylamine and beta-dicarbonyl
Object is closed to occur to be condensed and generate quinolines under acid catalysis and heating condition；It can be replaced by the method with synthesis of alkyl
The compounds such as oxyquinoline, ethoxycarbonyl oxyquinoline and other oxyquinolines；5) Friedlander method: the method mainly will be adjacent
Aminobenzaldehyde/ketone is reacted under the conditions of acid/base with the compound containing methylene ketone structure and obtains various substitutions
The quinolines of position；6) Povarov method: the method mainly generates multifarious quinoline by arylamine, aldehyde and alkyne reaction
Quinoline ring derivatives；7) Pfitzinger method: the method mainly passes through isatin (isatin) and methyl or methylene ketone in parent
Synthesis of quinoline class compound under the induction of core reagent (usually sodium hydroxide)；8) other liquid-phase synthesis process: as used arylamine
The quinoline that 3- halogen/sulphur replaces is obtained by electrophilic cyclisation, aromatization with acetylenic halide；And use 2- (amino methyl) benzene
Amine reacts under oxygen atmosphere with aryl ketones obtains 2- aryl quinoline product etc..Above-mentioned liquid-phase catalysis reaction method is quinolate at present
Close the most commonly used method of object industrialized production；However but there are many shortcomings that being difficult to avoid that in this method, be mainly manifested in: anti-
Should during using a large amount of organic solvent, reaction time is long, operating process tedious steps are more, target product yield needs to be mentioned
It is high；Catalyst is severe with very big corrosive strong acid or noble metal complexes, reaction condition expensive and be more toxic
Carve (such as some need reaction under high pressure condition), post catalyst reaction is difficult to separate and recover and generate the waste liquid of pollution environment.Cause
This, in face of increasingly strict environmental requirement and the more and more vigorous quinolines market demand, exploitation has environmentally protective
The quinoline compound technique for preparing of clean and safe production characteristic becomes inevitable.
Gas phase synthesis method has and does not use due to that can be effectively prevented from many drawbacks of bring in Traditional liquid phase reaction process
The significant advantages such as solvent, operation step be few, reaction process is simple, product and catalyst are easily isolated and recycle, more accord with
The trend for closing green chemistry, shows more preferably industrial applications potentiality.Campanati is catalyzed second two with montmorillonite K10
Pure and mild 2- ethyl aniline reaction；By improving the inlet amount of reaction temperature and ethylene glycol, while being passed through during the reaction a small amount of
Water, can get 41% 2- methyl -8- ethyl quinolinium yield.The patent report of McAteer et al. shows through formaldehyde, C2-
Three component reaction of C4 aldehydes and arylamine can get the quinolines of higher yields.Such as on BEA molecular sieve catalyst, first
The 3- methylquinoline that aldehyde, propionic aldehyde and aniline reaction obtain may be up to 67.7%.Subrahmanyam et al. uses HZSM-5,
The alkylation gas phase selectivity synthesis 2- of the catalysts such as CrHY, CeHY, LaHY, LaKHY and CeHZSM-5 quinoline and methanol
Methylquinoline；Especially on the modified LaKHY catalyst of two-component, methylquinoline is selectively 91.5%, and yield is up to
60.6%.Reddy et al. uses CuO-ZnO/Al2O3、MoO3-V2O5/Al2O3And NiO-MoO3/Al2O3Equal catalysts benzene
Amine and glycerine reaction generate quinoline, in the range of reaction temperature of 623-723K, in CuO-ZnO/Al2O3Quinoline is received on catalyst
Rate is up to 65%.Brosius et al., as catalyst, is catalyzed acetaldehyde and aniline synthesis using unmodified and F modified BEA zeolite
2-/4- methylquinoline.Especially F modified BEA zeolite catalyst can improve total receipts of quinoline compound to a certain extent
Rate and the distribution for changing product.Kamiguchi et al. uses metal halogen cluster compound catalysed aniline and acetone vapor- phase synthesis 1,2-
Dihydro -2,2, the catalytic performance of 4- trimethylquinoline, as [(Nb6Cl12)Cl2(H2O)4]·4H2O catalyst 300-400 DEG C with
On activated after, solid acid catalyst to target product have maximum selectivity.Existing research report confirmation, vapor phase method
Synthesis of quinoline class compound has preferable catalytic effect；It simultaneously can be neatly using different reactants as reaction raw materials.
But these current methods remain deficiency；It is mostly saturation/unsaturation aldehyde ketone of raw material from petroleum-based products in terms of raw material；
In terms of catalyst, there is catalytic activity that not high enough, catalytic active component is easy to run off and causes to be catalyzed for non-molecular sieve catalysts
The disadvantages of agent inactivates；The active poor and easy in inactivation of metal oxide catalyst；Though metal-organic framework materials catalyst has
Good reactivity, but material itself preparation difficulty it is big, at high cost, structural stability is poor the disadvantages of.
