Abstract
The present disclosure is directed to a method of manufacture of zeolite. A sol-gel formulation includes a water-soluble fraction of ODSO as an additional component. The resulting products include zeolite with increased crystallinity relative to comparable sol-gel formulations without ODSO as a precursor. In additional embodiments, the rate of crystallization of the zeolite is greater relative to comparable sol-gel formulations without ODSO.

A method for synthesis of crystalline material comprising:
- forming a sol-gel composition of precursors, reagents, water and water-soluble oxidized disulfide oil (ODSO) effective for the crystalline material;
- and
- heating the sol-gel composition under conditions and for a time effective to form a precipitate suspended in a supernatant, wherein the precipitate comprises a crystalline material, and wherein
- the crystalline material is characterized by a relative crystallinity that is greater than that of a comparative material, and/or crystalline material is formed at a crystallization rate that is greater than that of a comparative material, and wherein the comparative material is formed of approximately equivalent composition of components except for water instead of the added ODSO, and under approximately equivalent conditions and time.
