Disiloxanes and Functionalized Silica Gels: One Route, …

29/12/2015· Five novel disiloxane compounds comprising guanidinium and pyridinium moieties were obtained with high yields and purity. The verified synthetic pathways were then applied for modifiion of pre-functionalized silica gel, producing materials with the analogous organic side-chains. These halide-containing compounds and materials were then compared as to their ion-exchange properties: two

Crystal structure and spectroscopic behavior of …

27/6/2017· The crystal packing of both calcium oxalate–chloride double salts favors the directional bonding of oxalate, C 2 O 4 2−, ligands to calcium ions as do other related calcium oxalate minerals. The π-bonding between C and O atoms of the C 2 O 4 2− oxalate group leaves sp 2 -hydridised orbitals of the oxygen atoms available for bonding to Ca.

Gypsum - Wikipedia

Gypsum is moderately water-soluble (~2.0–2.5 g/l at 25 C) and, in contrast to most other salts, it exhibits retrograde solubility, becoming less soluble at higher temperatures. When gypsum is heated in air it loses water and converts first to calcium sulfate hemihydrate, (bassanite, often simply called "plaster") and, if heated further, to anhydrous calcium sulfate ().
