ABSTRACT OF DISCLOSURE A novel family of crystalline, microporous aluminophosphate compositions is synthesized by hydro- thermal crystallization at elevated temperatures of aluminophosphate gels containing a molecular structure- forming template. The family comprises a number of distinct species, each with a unique crystal structure. Calcination removes volatile extraneous matter from the intracrystalline void space and yields microporous crystalline adsorbents with uniform pores, the dimensions of which vary, along the individual species, from about 3A to 10A in diameter. The compositions represent a new class of adsorbents of the molecular sieve type, and also exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydro- carbon conversions.
