摘要: Zeolite L in very small crystalline form is prepared by a process in which an alkaline reaction mixture comprising water, a source of silicon (SiO₂), a source of alkali metal (M) (KOH) and a source of aluminium (Al₂O₃.3H₂O) or gallium is heated to a temperature of at least 80°C for a period of time long enough to form zeolite L, the composition of the reaction mixture having the following molar ratios (expressed as oxides):
where M is potassium or a mixture of potassium and one or more other alkali metals. Use thereof for the separation of the 1,5; 2,6 and 2,7 isomers of dimethyl naphtalene from one another.摘要翻译: 非常小的结晶形式的沸石L通过一种方法制备,其中包括水,硅源(SiO 2),碱金属(M)(KOH)源和铝源(Al 2 O 3·3H 2 O)的碱性反应混合物, 或镓加热至至少80℃的温度足够长的时间以形成沸石L,反应混合物的组成具有以下摩尔比(以氧化物表示):其中M是钾或其混合物 钾和一种或多种其他碱金属。 用于分离1,5; 2,6和2,7二甲基萘的异构体。
