CASE 1289 A B S T R A C T O F T H E D I S C L O S U R E An improved process is disclosed for producing alumino- -silicates having a porous structure, of the zeolite class, the process essentially comprising the step of preparing a homogeneous aqueous mixture containging a source of alu- mina, a source of silica and alkali metal bases and/or alkaline earth metal bases, the improvement consisting in adding to said mixture at least one substance which contains at least a hydroxyl group in its molecule. The advantages are that the use of nitrogenous organic substances, universally used heretofore for the preparation of certain zeolites, can be dispensed with inasmuch as the alkali metal ion is capable, alone, of displaying the counter-ion function.-
