In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Alkaline, mental, and acidic ranges [in papermaking], published in 2000, which mentions a compound: 17927-65-0, mainly applied to paper making neutral acidic condition; aluminum sulfate calcium carbonate interaction paper manufacture, Synthetic Route of Al2H8O13S3.
The manufacturing of papers is described under acidic and neutral operating conditions. The fabrication of papers under these conditions is based on the use of Al2(SO4)3.18H2O and CaCO3 as white pigments. The competing reactions of these 2 reagents are described and their advantages and disadvantages for paper production are discussed in relation to the pH value and the wood content of the papers.
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])Synthetic Route of Al2H8O13S3, and with the development of science, more effects of this compound(17927-65-0) can be discovered.
