Abstract
A fluorofurfurlazole cooling polymer used as the catalyst for preparing pyrocatechol by the hydroxylation reaction between phenol and H2O2 with high selectivity is prepared from fluorofurfurylazole and the chloride of transition metal through self assembling and culturing.
Description
Technical field:
The present invention relates to ligand polymer, preparation method and its usage that a kind of containing n-donor ligand and transition metal generate.
Background technology:
In recent years, the researchdevelopment of supramolecular chemistry is very fast, and utilizing crystal engineering to carry out that supramolecule constructs is one of major objective of supramolecular chemistry research, particularly has the ligand polymer of topological framework, has obtained unprecedented gazing at especially.Ligand polymer is that self-assembly under the condition of gentleness forms by transition metal and organic ligand, combine the characteristics of composite high-molecular and coordination compound, ligand polymer with multiple structures such as chain, latticed, trapezoidal, cage shapes is synthetic, because of its diversity structure, show unique character, have a extensive future at aspects such as nonlinear optical material, electrochemistry switch, magnetic, catalysis.The imidazoles of nitrogen atom and derivative thereof are because biologically active causes supermolecular scholar's interest.Wherein fluconazole is extensive use of as medicine, but does not still appear in the newspapers as the research of organic ligand and transition metal formation ligand polymer.
Dihydroxy-benzene comprises pyrocatechol, Resorcinol, Resorcinol, and they all are the important chemical products, have wide application field.Wherein pyrocatechol is the extremely wide fine chemical product of purposes, is basic raw material, intermediate or the auxiliary agent of industries such as rubber, medicine, agricultural chemicals, dyestuff, sensitive materials and spices, and domestic supply falls short of demand, long-term dependence on import.And pyrocatechol is difficult to separate with Resorcinol, so selectivity prepares pyrocatechol and is even more important.
The method for preparing pyrocatechol, domestic main industrialization synthesis method is the ortho chloro phenol hydrolysis method.This method is raw material with the ortho chloro phenol, and copper sulfate is catalyzer, and the reaction that is hydrolyzed in sodium hydroxide is the aqueous solution of alkaline medium generates pyrocatechol.This method needs press device, and the operational requirement height is produced 1.5 tons of sodium sulfate of 1 ton of pyrocatechol by-product.
2,4-disulfonic acid base phenol hydrolysis method is the method that early is used to prepare pyrocatechol, the technology comparative maturity, and price is low, but uses concentrated acid sulfonation phenol, the sodium hydroxide high temperature alkali fuse, the dilute sulphuric acid hydrolysis, equipment corrosion is serious, the operational condition harshness, quantity of three wastes is big.
With hydrogen peroxide the direct hydroxylation of phenol being become dihydric phenol is the research topic of a hot topic in recent years.On the one hand, this method technology is simple, and the degradation production of oxidants hydrogen peroxide only is O
2And H
2O can not cause any environmental pollution.On the other hand, this reaction and biological intravital oxidising process have some something in commons, so, cause chemist's extensive concern.This reaction process is considered to 21 century one of the most promising operational path.
Because hydrogen peroxide itself is not a hydroxylation reagent, must hydroxylating could take place by catalyzer on phenol, generate dihydroxy-benzene, therefore, to this method research maximum be catalyzer, the quality of product selectivity, the height of yield all depend on activity of such catalysts to a great extent.
So far, Chinese scholars is that phenol hydroxylation technology has selected a variety of catalyzer to study.External catalyst research is used comparatively sophisticated Japan, France, the Italy of mainly containing.They adopt the 60-70% hydrogen peroxide mostly.
From existing document, though the industrialization abroad of phenol hydroxylation preparing benzenediol, owing to reasons such as technical know-hows, the domestic industrialization of failing so far to realize.Transformation efficiency and product selectivity and the productive rate of investigator in order to improve phenol developed multiple catalyzer, but because corrodibility is strong, cost is high, catalyst recovery difficulty etc. is multiple former thereby all not fully up to expectations.Be development ideal catalyzer, chemist is all being done unremitting effort.
Patent that Jilin University delivers adopts the polyacid title complex of Dawson structure, and to be catalyzer (patent No. 94120162.7) make oxygenant at 70 ℃, hydrogen peroxide, acetonitrile is under the condition of solvent, though good selectivity is arranged by the phenol preparing benzenediol, but phenol conversion is low, and the acetonitrile contaminate environment.The patent (patent No. 94120019.1) of Changchun Inst. of Applied Chemistry, Chinese Academy of Sciences's invention adopts the Y shaped molecular sieve, according to the preparation difference of molecular sieve, can react in different solvents.Jilin University adopts micro-porous resin embedding nano particle to make catalyzer (patent No. 96105181.7), and China PetroChemical Corporation is catalyzer (patent No. 99113282.3) with the copolymer pellet of vinylbenzene and MALEIC ANHYDRIDE.In fact, seeking with water is that solvent carries out the phenol hydroxylation catalyst for reaction, and promptly carrying out so-called " cleaning procedure " reaction is the current problem that chemist is had the challenge meaning.
Find the document of home and abroad according to us, do not see the report of making catalyst hydroxylation with hydrogen peroxide phenol of ligand polymer as yet.Technical study about fluconazole and transition metal reaction generation ligand polymer does not more appear in the newspapers.
Summary of the invention:
For solving low, a series of problems such as catalyst recovery is difficult, solvent contamination environment of poor selectivity, productive rate that the phenol hydroxylation reaction generates dihydroxy-benzene, the invention provides a kind of fluconazole ligand polymer of utilizing nitrogenous organic compound fluconazole and transition metal chloride self-assembling reaction to make, the method for preparing this catalyzer also is provided, this polymkeric substance can be used as catalyzer and is used for the phenol hydroxylation with hydrogen peroxide reaction, the preparation pyrocatechol.
