| Calcium Sulfite | Calcium sulfite, or calcium sulphite, is a chemical compound, the calcium salt of sulfurous acid with the formula CaSO3. In presence of moisture it commonly forms the hemihydrate CaSO3.0.5H2O. Its uses as the pure compound are limited, such as a food additive, but it is produced in large quantities during flue gas desulfurization (FGD) with lime, which then exposed to air converts to common calcium sulfate (CaSO4, more exactly the gypsum form, CaSO4.2H2O) by oxygen scavenging, this route of CaSO4 production via CaSO3 intermediate being the main source of drywall wallboard. Group: Water treatment. Alternative Names: Calcium Sulfite. CAS No. 10257-55-3. Molecular formula: CaO3S. Mole weight: 120.14. IUPACName: calcium; sulfite. Canonical SMILES: [O-]S(=O)[O-].[Ca+2]. ECNumber: 243-873-5. Catalog: ACM10257553. |  |
| Lignosulfonic acid calcium salt | Calcium lignosulfonate is a multi-component high molecular polymer anionic surfactant, the appearance is light yellow to dark brown powder, slightly aromatic odor, the molecular weight is generally between 800 and 10000, with strong dispersibility, Adhesion and chelation. It is usually spray-dried from cooking waste liquor from acid pulping (or sulfite pulping). Uses: Application granulating agent for limestone and ores, compaction aid for coal and metal wastes, and dispersing agent for gypsum and clay slurries. Group: Natural polymers and biopolymers.
