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 State of water in the dehydration products of beryllium and aluminum sulfates, published in 1973, which mentions a compound: 17927-65-0, mainly applied to NMR dehydration product hydrate; beryllium sulfate hydrate NMR; aluminum sulfate hydrate NMR; magnesium sulfate hydrate NMR, Reference of Aluminum(III) sulfate xhydrate.
The NMR of BeSO4.4H2O, Al2(SO4)3.18H2O and of the products of their dehydration were determined Some details of the NMR spectra of MgSO4.7H2O and its dehydration products were also investigated. Substantial increase of the interproton distance was observed in all the sulfates studied possessing low amounts of H2O. This phenomenon is explained by the strong polarization of the H2O mols. and by expansion of the O-H bonds.
As far as I know, this compound(17927-65-0)Reference of Aluminum(III) sulfate xhydrate can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
