Description

The method of synthesizing P-Al molecular sieve or aluminium silicophosphate molecular sieve in strong basicity system
Technical field
The invention belongs to the technologies of preparing of molecular sieve, more particularly to synthesizing P-Al molecular sieve or silicon phosphorus in strong basicity system The method of aluminum molecular screen.
Background technology
The beginning of the eighties in 19th century, U.S. combinating carbide company (U.C.C) develop after phosphate aluminium molecular sieve (AlPO-n) A kind of novel molecular sieve material, aluminium silicophosphate molecular sieve (SAPO-n).The skeleton of SAPO-n is by SiO2、AlO2 -、PO2 +Three kinds of four sides Body basic unit is constituted so that being in the skeleton of the AlPO-n molecular sieves of electroneutral originally has tradable charge, forms class It is similar to the Bronsted acidity of Si-Al molecular sieve, while the thermostabilization with AlPO-n molecular sieves and hydrothermal stability again.Thus, SAPO-n molecular sieves have been widely used in catalysis industry field because of its excellent physico-chemical property.
Since molecular sieve research and industry are closely bound up, the exploration of new Zeolite synthesis route is closed as researchers The hot spot of note.The characteristics of earliest Zeolite synthesis route synthesizes for hydro-thermal method, the route is using a large amount of water as solvent It is synthesized.And need to use using phosphoric acid as phosphorus source, in commercial Application, it is not only be easy to cause environmental pollution, is also unfavorable for Industrial operation.
Large-scale application is still hydro-thermal method route in industrial synthetic route at present, and colloidal sol is required in synthesis condition PH value is neutral or faintly acid in system.If aluminium phosphate molecular sieve or silicon phosphorus aluminium molecule can be made under alkaline system Sieve, it will be an important breakthrough.
