Patent GB-1018038-A (GB)
Title: Synthetic zeolite
IPC: C01B39/14
Filed: 1962-07-25
Abstract: The invention comprises a crystalline synthetic zeolite having the composition 0.1 to 0.3 M2O: 0.7 to 1.0 X2O: 1 Al2O3: 2.5 to 4.0 SiO2. Y H2O where M is methyl ammonium, X comprises sodium, potassium, a cation exchanged for the sodium or potassium, or any mixture thereof, and especially sodium, or potassium, and Y is any value from 3.5 to 5.5, and the material which has been activated to convert the methyl ammonium wholly or partly to hydrogen.  The product is synthesized by preparing a reaction mixture containing M2O, X2O, Al2O3 and SiO2 of stated composition ratios and maintaining said mixture at a temperature within the range of 20 to 120 DEG  C., until the crystalline material is formed. The crystals produced are separated from the mother liquor, and activated by heating at a temperature from 200 DEG  to 600 DEG  C. Suitable starting materials for the synthesis comprise amorphous sodium alumino silicate gel and tetramethyl ammonium silicate, sodium aluminate and tetramethyl ammonium silicate, sodium alumino silicate gel and tetramethyl ammonium hydroxide, or sodium aluminate and tetramethyl ammonium di-silicate tetrahydrate with tetramethyl ammonium hydroxide.  The zeolite which is designated ZK4 exhibits excellent absorption of water, and straight chain aliphatic hydrocarbons including n-hexane, will reject branch chain hydrocarbons such as 3-methyl pentane and cyclic hydrocarbons such as cyclohexane.  The sodium or potassium atoms may be replaced by known ion exchange techniques with any metal, when ZK4 is in the methyl ammonium form but once activated the anion must not be acidic in nature, since this leads to the destruction of the zeolite structure.  The examples which refer also describe the synthesis of the tetra-methyl ammonium form of ZK4, in one instance using ethyl-orthosilicate as a source of silica gel.ALSO:Zeolite K-4 which has the composition 0,1-0,3 M2O:0,7-0,1 X2O:1 Al2O3:2,5-4,0 SiO2.  Y H2O where M is methylammonium, X comprises sodium, potassium, any cation exchanged for the sodium or potassium or any mixture thereof and Y is any value from 3,5-5,5 or the activated zeolite ZK4 especially when activated by thermal treatment at between 200-600  DEG C., whereby the methyl ammonium is wholly or partly converted to hydrogen, is suitable for absorbing molecules whose critical dimension is less than 5,5  such as water, normal alkanes up to C6 or for use as catalysts depending upon the nature of the cation inserted into the structure.  Cations said to be exchangeable include monovalent or divalent cations such as lithium and magnesium, calcium and strontium, transition metals such as nickel, the rare earth metals such as cerium.  The lanthanides, the transition metals of atomic numbers 21-28, 39-46, and 72-78 inclusive, namely scandium, titanium, vanadium, chromium, manganese, iron, cobalt, nickel, yttrium, zirconium, niobium, molybdenum, ruthenium, rhodium, palladium, platinum, hafnium, tantalum, tungsten, rhenium, osmium and iridium are also stated to be exchangeable.
