In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Synthesis of hydrated aluminum sulfate from kaolin using microwave energy, published in 1998-08-31, which mentions a compound: 17927-65-0, Name is Aluminum(III) sulfate xhydrate, Molecular Al2H8O13S3, Category: isothiazole.
Hydrated aluminum sulfate, an inorganic polymer, was synthesized from kaolin in H2SO4 solution using microwave energy. The maximum rates of alumina extracted from calcined kaolin were 72.8% in a conventional process (80°, 1M, and 180 min) and 99.9% in a microwave process (90°, 1M, and 60 min). Compared with the conventional one, the hydrated aluminum sulfate synthesized under the microwave process had layer structure consisting of plate-shaped large grains. After synthesis and then calcination at 1100°, both products in conventional and microwave processes were γ-Al2O3 with agglomerated powders of spherical shape. The specific area of the products in conventional and microwave processes were 113.5 and 106.6 m2/g, and their average grain sizes were 46.5 and 26.3 μm, resp.
After consulting a lot of data, we found that this compound(17927-65-0)Category: isothiazole can be used in many types of reactions. And in most cases, this compound has more advantages.
