The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Solubility and solid phases in the sulfuric acid-sodium sulfate-aluminum sulfate-water system at 50°》. Authors are Lepeshkov, I. N.; Danilov, V. P.; Selin, A. N.; Kim, V. P.; Zaitseva, L. A.; Gorbacheva, N. N..The article about the compound:Aluminum(III) sulfate xhydratecas:17927-65-0,SMILESS:O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al]).Quality Control of Aluminum(III) sulfate xhydrate. Through the article, more information about this compound (cas:17927-65-0) is conveyed.
Solubility and composition of the solid phases in the H2SO4-Na2SO4-Al2(SO4)3-H2O system were determined for H2SO4 concentrations of 3-12 weight%. Under the given conditions Na2SO4, NaAl(SO4)2.12H2O and Al2(SO4)3.17H2O crystallize.
There is still a lot of research devoted to this compound(SMILES:O=S(O)(O)=O.O=S(O)(O)=O.O=S(O)(O)=O.[H]O[H].[Al].[Al])Quality Control of Aluminum(III) sulfate xhydrate, and with the development of science, more effects of this compound(17927-65-0) can be discovered.
