Description
Technical field
The invention discloses a kind of preparation method of molecular sieve, use ionic liquid as reaction medium specifically, agent prepares AlPO as auxiliary template by adding amine
4Or the method for SAPO molecular sieve.
Background technology
Molecular sieve is with its many special performances, and for example ion exchangeable, diffusion and adsorptivity, shape selectivity and catalytic activity etc. are subjected to people's extensive studies for a long time always and are applied to a plurality of fields.For example in current commercial catalysts, molecular sieve is a class catalyzer the most widely of using.This mainly is to have utilized distinctive pore passage structure, acidity and the absorption property that they had.And the synthetic synthetic method that has the molecular sieve of new texture and develop new molecular sieve is the emphasis that the scientific research personnel works always.
The synthetic method of traditional molecular sieve mainly comprises the synthetic and solvent thermal synthesis method of hydro-thermal.Building-up reactions generally in the container of particular type or autoclave, carry out and react in often need to use template.Recently, researchists such as Morris have been developed a kind of synthetic method of new molecular sieve, i.e. ion thermal synthesis method.This new synthetic method and traditional hydro-thermal and the difference of solvent process for thermosynthesizing are: use the solvent of ionic liquid as reaction, and also can serve as the effect of template as the ionic liquid of solvent simultaneously.Ionic liquid be meant constitute by the relative less inorganic anion of the relatively large organic cation of specific volume with volume, in room temperature or be bordering on the material that is in a liquid state under the room temperature.Compare with solid matter, it is liquid; Compare with traditional fluent meterial, it is an ionic.Ionic liquid comprises following characteristics: non-volatile or negligible vapour pressure; Low melting point; Wide liquid journey; Wide electrochemical window; High thermal stability; Selective dissolution power.These characteristics make ionic liquid become to have concurrently " solid " liquid of liquid and solid function and characteristic.And, theoretically, trillion kinds of possible ionic liquids of surpassing are arranged.Ion liquid diversity adds the combination of various characteristics, makes that constituting a large amount of character functional materials and medium different with purposes becomes possibility.
Just because of ion liquid special nature, make the ion process for thermosynthesizing have some traditional hydro-thermals and the not available characteristic of solvent process for thermosynthesizing.For example, because ion liquid non-volatile, ion thermal synthesis reaction can not carried out in autoclave, and can adopt unlimited easy Glass Containers, so just can avoid because a series of unsafe factor that high pressure brought.In addition, owing to have multiple possible ionic liquid, and ionic liquid can be used as template in the ion thermal synthesis, therefore by using different ionic liquids just might synthesize the molecular sieve of multiple different structure as reaction medium.In addition, current studies show that, even use with a kind of ionic liquid as reaction medium, also can obtain the molecular sieve of multiple structure.But, the ion thermal synthesis method also exists certain weak point.For example, what often obtain in building-up process is the mixture of several different structure molecular sieves, is difficult to sometimes improve certain product selectivity by the modulation reaction conditions, thereby is difficult to obtain the product of pure phase.
