The structure type code was introduced by lUPAC (International Union of Pure and Applied Chemistry) to try to simplify the notation of zeolite structures. In the past several researchers had produced the same basic zeolite by different laboratory methods. The zeolite thus obtained was named by that researcher and resulted in a system where one zeolite structure was known by up to 20 different trade names This led to a great deal of confusion and so the three-letter code was introduced. So for example zeolite A (produced using sodium hydroxide, alumina and silica) and zeolite ZK4 (produced using tetramethylammonium hydroxide, alumina and silica) have the same structure, now denoted LTA (H). [Pg.235]

MFI stands for Mobil Five and ZSM stands for Zeolite Socony Mobil. Detailed information about the structure-type codes can be found on the homepage of the Structure Commission of the International Zeohte Association (IZA) at http //www.iza-structure.org. [Pg.316]
