Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 17927-65-0, is researched, SMILESS is O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al], Molecular Al2H8O13S3Journal, Yogyo Kyokaishi called Synthesis of hexagonal plate-like α-alumina crystals by using hydrated aluminum sulfate as the starting material, Author is Daimon, Keiji; Kato, Etsuro, the main research direction is alumina alpha preparation particle size; sulfate aluminum dehydration thermolysis.HPLC of Formula: 17927-65-0.
Hexagonal plate-like α-Al2O3 crystal was prepared by dehydration of Al2(SO4)3.14-18 H2O (I) at 300° for 24 h or at 200° under reduced pressure, followed by the formation of η-Al2O3, by heating the anhydrous Al2(SO4)3 at 900° for 4 h and finally by mixing with 25% weight AlF3 and heating in Pt tube at 900-1200°. The particle size distribution of α-Al2O3 was wider for the I dehydrated at 200° under reduced pressure than for the I which was dehydrated by evaporation after it was dissolved in water. The particle size of α-Al2O3 obtained by 900° heat-treatment was greater than that obtained by 1100° heat-treatment.
