Abstract
The present invention discloses a process for condensing salicyladehyde and aryl amine, which is carried out according to the following steps: adding the salicylaldehyde and the aryl amine to a reaction vessel; putting the salicylaldehyde and the aryl amine in a microwave device of 600 to 800 W; cooling the salicylaldehyde and the aryl amine after reacting for 2 seconds to 6 minutes; crystallizing the salicylaldehyde and the aryl amine. In the present invention, a method in which a microwave is used to promote chemical reaction is adopted to ensure that the reaction of condensing and synthesizing aldehydeamine into schiff bases can efficiently occur under the condition of no solvent, short reaction time and high yield; therefore, the present invention has the advantage of little environmental pollution, and is suitable for producing a schiff base compound and derivants thereof in small amount, multiple kinds and no nuisance.
Description
The present invention relates to the synthetic method of a series of salicylic alidehyde imine compounds, particularly a kind of method of producing the salicylic alidehyde imine compound by salicylic aldehyde and aromatic perfume amine condensation.
The organic chemistry develop rapidly benefits from the foundation (1874 of carbon tetravalence theory, Holland chemist Jacobus Hendricus van ' t Hoff), and the aldimine condensation reaction western Buddhist alkali of formation (Schiff-base) launches (Ann.Chem.1869 before the theoretical proposition of carbon tetravalence, 150 volumes, 193 pages), be the earliest one of Chemical Problem in the organic chemistry research, thereby with investigator's naming.Although to aldimine condensation reaction having carried out systematic research, yet because the critical role of carbon-to-nitrogen double bon in the heteroato mic organic compound, still be widely used in the synthesizing of medicine, agricultural chemicals and organic chemical industry's product.Thermal chemical reaction is generally adopted in this class reaction, needs solvent to make medium, and environment is being produced certain pollution; Simultaneously, react length often consuming time (several hours to a couple of days), the productive rate height does not wait.In order to improve reaction efficiency and to make full use of the natural resources, realize the synthetic of some unknown compounds, enrich western Buddhist alkali cpd family, enlarge using value and the Application Areas of western Buddhist alkali in people's daily life and industrial and agricultural production, need to inquire into new western Buddhist alkali synthetic method.
The objective of the invention is to overcome in the thermal response of the synthetic western Buddhist alkali of traditional aldimine condensation, need solvent, reaction times is longer, aftertreatment is trouble, the productive rate instability has the shortcoming of pollution to environment, and a kind of method that adopts microwave to promote chemical reaction is provided, make that being reflected at of the synthetic western Buddhist alkali of aldimine condensation is solvent-free, the reaction times short and high yield under efficiently carry out, environmental pollution is little.Be applicable to short run, many kinds, nuisanceless western Buddhist alkali cpd and the derivative thereof produced.
Microwave of the present invention promotes the reaction expression of the synthetic western Buddhist alkali of aldehyde ketone condensation reaction to be:
Western Buddhist alkali general structure of the present invention is:
Ar is respectively: 5-methyl isophthalic acid H-pyrazole-3-yl, 2-anisole-1-base, pyridine-2-base, 6-picoline-2-base; 2,6-dimethyl benzene-1-base, 2; 3-dimethyl benzene-1-base, 4,6-lutidine-2-base; 5-methyl-isoxazole-3-base, 5-picoline-2-base, 4-picoline-2-base; 3-benzyloxy pyridine-2-base, 3-chloro-5-5-flumethiazine-2-base, 5-Shu butyl isoxazole-3-base; 6-ethylpyridine-2-base, 4,6-dimethyl pyrimidine-2-base; 3,5-two bromo-6-picoline-2-bases, 4-ethylpyridine-2-base; 3-acetylbenzene-1-base, different quinone quinoline-1-base, 3; 5-dibromo pyridine-2-base, 5-bromopyridine-2-base, 5-ethylmercapto group-1; 3,4-thiadiazoles-2-base, 4-chloro-2-Benzoylbenzene-1-base; 9-Fluorenone-1-base, different quinone quinoline-5-base, diphenyl-methyl; 5-ethyl-1,3,4-thiadiazoles-2-base; acridine-9-base, 2-hydroxybenzene-1-base, 2; 6-diisopropyl benzene-1-base, 4-methylbenzothiazole-2-base, 2-carboxyl benzene-1-base.
