(JA) ＺＭＳ－５ゼオライトの改良された製造方法

Abstract

(JA)

ＺＭＳ−５ゼオライトの合成方法であって、（ａ）アルミン酸ナトリウム水溶液と珪酸ナトリウム水溶液の２種を調製する工程と、（ｂ）前記２種の溶液を、攪拌下、室温で相互に接触させる工程と、（ｃ）OH^-/H₂Oモル比が0.02〜0.03となるような量の無機酸の溶液を、溶液（ａ）もしくは溶液（ｂ）又は溶液（ａ）＋（ｂ）に添加する工程と、（ｄ）反応混合物の流動性を保ち、OH^-/H₂Oモル比が0.017〜0.022となるのに十分な量の水を添加する工程と、（ｅ）前記工程（ａ）〜（ｄ）の最後に得られた最終混合物を20〜60℃で予熱する工程と、（ｆ）混合物を攪拌下、温度100〜200℃で加熱する工程とから本質的になる方法。
