  • Method for controlling synthesis conditions during molecular sieve synthesis using combinations of quaternary ammonium hydroxides and halides
    Publication number: 20040234449
    Abstract: To control the pressure generated by the decomposition of quaternary ammonium hydroxides during the crystallization of molecular sieve materials at elevated temperatures, to levels below the mechanical limits of the equipment, the present invention substitutes halide salts of the same quaternary ammonium structure directing agent compound for some fraction of the hydroxide compound. In addition, because the quaternary ammonium hydroxides are generally more expensive than the corresponding halides, using a combination of the two reduces the cost of manufacturing the molecular sieve product.
    Type: Application
