    摘要: A novel family of crystalline, microporus aluminophosphate compositions is synthesized by hydrothermal 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 microporus crystalline adsorbents with uniform pores, the dimensions of which vary, among the individual species, from about 3A to 10A diameter. The composition exhibit properties somewhat analogous to zeolitic molecular sieves which render them useful as catalysts or catalyst bases in chemical reactions such as hydrocarbon conversions.

    摘要: Stable, colloidal, silica sol is provided by a process which comprises vigorously mixing a slurry of calcium silicate with a dilute acid having a pK.sub.a value of less than about 8, such as sulfuric acid, and thereafter separating the sol from the insoluble precipitate of calcium salt. The process provides an inexpensive method for production of the sol as opposed to those methods which currently use sodium silicate as the starting material.
