The preparation of ester heterocycles mostly uses heteroatoms as nucleophilic sites, which are achieved by intramolecular substitution or addition reactions. Compound: Aluminum(III) sulfate xhydrate( cas:17927-65-0 ) is researched.SDS of cas: 17927-65-0.Pradhananga, Trinetra M.; Matsuo, Sadao published the article 《Deuterium/hydrogen fractionation in sulfate hydrate-water systems》 about this compound( cas:17927-65-0 ) in Journal of Physical Chemistry. Keywords: deuterium isotope fractionation ion hydration; sulfate hydrate water isotope fractionation; transition metal sulfate hydrate structure. Let’s learn more about this compound (cas:17927-65-0).
The D/H fractionation factors (α) of some of the sulfate hydrate-H2O systems were measured. A dependence of α on cationic parameters and M-H2O distance was found. The D/H fractionation factors of various hydrate-water systems were divided into 2 groups with respect to their α values: one having α < 1 and the other α > 1. There is almost no change in α for crystal-H2O systems having SO42- as the anion of the 1st transition metal ion series from Fe2+ to Zn2+, except for Cu2+. This is related to the common structure of the hydration sphere of cations and the common distance of M-H2O. The exceptional case for Cu2+ is attributed to the distorted structure of octahedra surrounding Cu2+. A similar type of behavior of protons leading to the residual entropy was found in some of the crystal-H2O systems having α > 1.
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])SDS of cas: 17927-65-0, and with the development of science, more effects of this compound(17927-65-0) can be discovered.
