Zeolite L. |
摘要 |
<p>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 DEG 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): <IMAGE> 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.</p> |
