HCID 26051Sodium orthosilicate

Product 1

HCID 19758701Molecular sieve

Procedure

U.S. Pat. No. 3,424,602 to Nauroth mixes a soluble sodium silicate with an aluminum sulfate solution to form sodium alumino silicate precipitates. The final product is also different from the alumina-silica-sulfates of this invention in that the precipitate is a product substantially lacking in sulfate content, with sulfate only present as sodium sulfate by-product.
