Abstract
Process for the synthesis of precursors of molecular sieves of the silicoaluminophosphate type by heating to .gtoreq.100.degree. C. under autogenous pressure a reaction mixture containing sources of silicon, aluminum and phosphorus in the presence of an organic structuring agent and of hydrofluoric acid. The precursor obtained can be converted into molecular sieve by calcination. Molecular sieves of the silicoaluminophosphate type can be used as adsorbants and catalysts for the conversion of hydrocarbons.
