Abstract
The invention relates to a synthesis method of tris-(4-tetrazolyl-phenyl)amine, belonging to the field of material chemistry. The technical scheme of the invention is as follows: reacting diphenylamine with halo-benzene under a basic condition to obtain triphenylamine, carrying out substitution reaction on triphenylamine with iodine to generate tris-(4-iodophenyl)amine, then reacting tris-(4-iodophenyl)amine with CuCN to generate tris-(4-cyanophenyl)amine, and finally reacting tris-(4-cyanophenyl)amine with sodium azide to generate tris-(4-tetrazolyl-phenyl)amine. The porous material built by reacting obtained tris-(4-tetrazolyl-phenyl)amine with a metal has the stability of carboxylic acid porous frames, achieves intra-pore functionalization, and has pores in a mesoporous size. The adsorption capacity with respect to specific sulfur-containing small molecules shows that the porous material has potential application value in developing high-performance petrochemical products.
Description
Technical field
The invention belongs to the materials chemistry field, particularly the synthetic method of the intermediate of preparation one class functional porous material.
Background technology
Exhaust environment pollution problem, serious harm be to ecotope and human life and health, become in the world one of serious environmental problem at present.And being the burning of fossil energy, the main source of topsoil causes.At present, fossil energy utilize mode still based on burning, and will continue a very long time.Deleterious S, N, F, As, P(all contain lone-pair electron to) etc. be converted into the compound-SO of oxidation state
x, NO
x, P
2O
5, etc.And SO
x, NO
xA large amount of dischargings make air quality gather deterioration, form acid rain, environment for human survival and mankind itself are produced huge harm; Very serious to buildings and all kinds of facility corrosion harmfulness.And the non-burn application of fossil oil (chemical and industrial chemicals) mainly contains the then corresponding H of being converted into of harmful substances
2S, organosulfur, NH
3, HF, PH
3, AsH
3These objectionable impuritiess have toxic action to the catalyzer of the deep-processing process of oil.At this moment because: most of nitride, sulfide, there are lone-pair electron in phosphide, with the surface of metal catalyst very strong bonding action is arranged, and compares with reactant, has bigger adsorption index.The absorption of these objectionable impuritiess on catalyzer has stoped the diffusion of reactant to the active centre, thereby makes catalyzer lose effectiveness.Therefore, in Chemical Manufacture and fuel oil use, must carry out purifying treatment to raw material.
How remove these objectionable constituent from the source: mainly be N, P, the S pollutent is produced clean fuel oil, just has very much meaning.And main focus is how to reduce the content of sulphur from gasoline or diesel oil.At present, and United States Department Of Transportation the latest requirement of gasoline and diesel oil sulphur content be respectively be less than 30 and 15ppm(
Official J. Eur. Communities2003
, L76,10.).And the sulphur content of widely used gasoline of China and diesel oil is too high: domestic gasoline sulfure content is generally at 300 ~ 800ppm, even higher, to all being very disadvantageous on environment and the energy consumption.And the washing of traditional strong oxidizer, rectificating method is difficult to realize the purpose of this deep desulfuration.Simultaneously, there is high security risk especially in the strong oxidizer desulfurization.To all being adverse factors on environment and the energy consumption: the too high gasoline combustion of sulphur content can cause the Pd of purifying vehicle exhaust treatment system, and noble metal catalysts such as Pt are poisoned, thereby cause a large amount of environmental pollution gas NO
xDirectly discharging enters atmosphere.

IThe adsorption experiment of the porous material that Y type cation zeolites is constructed finds that this material is extremely strong to the absorption of the thiophenic sulfur in the fuel oil at normal temperatures and pressures, can realize that sulphur content is from 430 ppm → 0.2 ppm in the fuel oil, (R. T. Yang, A. J. Hern á ndez-Maldonado, F. H. Yang
Science.2003
, 301,79-81.). the desulphurizing ability of this degree of depth is to come from cationic metal center S → M coordination and M → π effect in thiophenic sulfur molecule and this loose structure; The main component of gasoline and diesel oil is each family's hydro carbons; The metal center of porous material is to its almost not effect; And sulphur atom is had certain weak coordination; Therefore can realize the adsorption and enrichment to sulfurous organic compound in the liquid phase; Reach purpose (the C. Laborde-Boutet of reduce fuel oil sulfur content; G. Joly; A. Nicolaos; M. Thomas; P. Magnoux Ind Eng. Chem. Res.2006
, 45,6758-6764).Yet because the too small limitation of this inorganic zeolitic material duct size (easy plugging hole road junction behind the adsorbed molecules) and regeneration capabilities limits (destruction that too high temperature regeneration causes material structure self) make it be difficult to the industrial application of reality.
So, seek a kind of porous material that has macropore size more and have a metal function site and just seem very important.
Contain more macropore for how to construct, traditional inorganic porous material (mainly being zeolite, molecular sieve) is to be difficult to realize.And Yaghi etc. utilize the fragrant polyacid and the metal ion (hybrid inorganic-organic materials) of rigidity and better heat stability, by the solvent thermal technology, the carboxylic acid of selecting different size is as connected body, though the size in duct from 3.8 to 28.8 in the realization polymkeric substance, the hole free volume has reached the porous material (MOFs) of 91.1% hybrid inorganic-organic of material cumulative volume when maximum

)But, but be difficult to the metal site functionalization in its duct of realization.Therefore, do not possess the application of this aspect yet.
Because the immobilized hybrid inorganic-organic materials in vesicular structure of metal center has many advantages:
(1) metal active center and duct size can be controlled design, and the duct size can be enough big, can be because of not stopping up the duct behind the adsorbed molecules;
(2) metal center homodisperse, contact area is big, and loading capacity is big;
(3) the hybrid inorganic-organic crystalline material is insoluble to fuel oil, and reaction is easy to handle, and the easy-to-use alcoholic solvent of material carries out low-temp recovery.Realize reusing, this has more realistic meaning in industrial application.
The contriver makes a kind of Cu-UMCs-MOFs porous cubic system material that can be used for deep desulfurization of fuel oil by the synthetic method, this material has the scope of application of broad, this material is extremely strong to the absorption of the thiophene sulphur in the fuel oil at normal temperatures and pressures, can realize that desulfurization content is reduced to below the 10ppm in the fuel oil.And the intermediate of synthetic this material---three-(4-tetrazole base phenyl) amine are one of keys.
