7757-82-6 Usage

General Description

Sodium sulfate, also known as sulfate of soda, is an inorganic compound with the chemical formula Na2SO4. It's a white crystalline solid that is odorless and highly soluble in water. This sodium salt of sulfuric acid is typically used in the manufacturing of detergents, glass, and paper, although it also has applications in textiles, the food industry, pulp and paper, and other various chemical reactions. Sodium sulfate is non-toxic but can cause redness or irritation when in contact with eyes and skin. While not considered highly hazardous, it should still be handled with care and stored properly to avoid accidental exposure or spillage.

Check Digit Verification of cas no

The CAS Registry Mumber 7757-82-6 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,7,5 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 7757-82:
(6*7)+(5*7)+(4*5)+(3*7)+(2*8)+(1*2)=136
136 % 10 = 6
So 7757-82-6 is a valid CAS Registry Number.

Studies on synthetic galloalunites AGa3(SO4) 2(OH)6: Synthesis, thermal analysis, and X-ray characterization

Rudolph, Wolfram W.,Schmidt, Peer

, p. 112 - 120 (2011)

Stoichiometric end member galloalunites of the general formula AGa 3(SO4)2(OH)6, with A = Na +, K+, Rb+, H3O+, and NH4+ have been synthesized under hydrothermal conditions. These galloalunites were characterized by chemical methods, thermal analysis (DSC, TG coupled with mass spectroscopy), and powder X-ray diffraction (XRD). The stages of thermal decomposition of sodium, potassium and rubidium galloalunite show a common decomposition mechanism forming β-Ga 2O3 and A2SO4 (A = Na+, K+, and Rb+) while ammonium and oxonium galloalunite decompose under formation of pure β-Ga2O3. The thermogravimetric results confirmed the analytical results on the galloalunites and thereby verified the stoichiometry of these synthetic products. Galloalunites with different monovalent cations in A site (i.e. Na+, K+, Rb+, H3O+ and NH 4+) crystallize in the rhombohedral space group R3m (#166). The effects of substitution on the unit cell parameters are rationalized in terms of the structural arrangements in galloalunites. The unit cell parameter c increases with increasing effective ionic radii of the cation in the A site, whereas the parameter a changes to a much lesser degree.

Water-dissolvable sodium sulfate nanowires as a versatile template for the fabrication of polyelectrolyte- and metal-based nanotubes

This study presents the synthesis of water-dissolvable sodium sulfate nanowires, where Na2-SO4 nanowires were produced by an easy reflux process in an organic solvent, N,N-dimethylformamide (DMF) and formed from the coexistence of AgNO3, SnCl2, dodecylsodium sulfate (SDS), and cetyltrimethylammonium bromide (CTAB). Na2SO 2 nanowires were derived from SDS, and the morphology control of the Na2SO4 nanowires was established by the cooperative effects of Sn and NO3-, while CTAB served as the template and led to homogeneous nanowires with a smooth surface. Since the as-synthesized sodium sulfate nanowires are readily dissolved in water, these nanowires can be treated as soft templates for the fabrication of nanotubes by removing the Na2SO4 core. This process is therefore significantly better than other reported methodologies to remove the templates under harsh condition. We have demonstrated the preparation of biocompatible polyelectrolyte (PE) nanotubes using a layer-by-layer (LbL) method on the Na2SO 4 nanowires and the formation of Au nanotubes by the self-assembly of Au nanoparticles. In both nanotube synthesis processes, PEI (polyethylenimine), PAA (poly(acrylic acid)), and Au nanoparticles served as the building blocks on the Na2SO4 templates, which were then rinsed with water to remove the core templates. This unique water-dissolvable template is anticipated to bring about versatile and flexible downstream applications.

Cation-tuned synthesis of the A2SO4·SbF3 (A = Na+, NH4+, K+, Rb+) family with nonlinear optical properties

Four antimony fluoride sulfates named A2SO4·SbF3 (A = Na+, NH4+, K+, Rb+) have been successfully synthesized using a hydrothermal method by introducing Sb3+ cations with a stereochemically active lone pair in sulfates and subsequently tuning the structure through the second monovalent cations. All of the title compounds are stoichiometrically equivalent materials which share a common structural motif composed of a distorted SO4 tetrahedron and an asymmetric SbF3 polyhedron. However, the macroscopic centricities of these four compounds are significantly influenced by the size and coordination environment of cations; Na2SO4·SbF3 crystallizes in centrosymmetric space groups Cmca and (NH4)2SO4·SbF3 in Pbca, while K2SO4·SbF3 and Rb2SO4·SbF3 crystallizes in noncentrosymmetric space group P212121. Complete characterization including thermal analyses, infrared and UV-vis spectroscopy, and theoretical calculations is also reported. Powder second harmonic generation measurement for noncentrosymmetric K2SO4·SbF3 and Rb2SO4·SbF3 indicated that both of them are type I phase-matchable.

PROCESS

, (2021/09/26)

In a process for treating wastewater from a combined gasification and Fischer-Tropsch (F-T) process, feedstock derived from Municipal Solid Waste or the like is gasified in a reactor (R) and treated in a cleanup unit (C) which generates a first wastewater stream (1st WWT STREAM) containing salts and inorganic pollutants. The first wastewater stream is treated in a treatment unit (T1) to remove inorganic pollutants derived from the syngas. The treatment comprises a) degassing, and subsequently b) neutralising the first wastewater stream before treatment in a Dissolved Air Flotation unit (72c) and filtering in a moving sand bed or similar (72d) to remove solids, and a stripping process to remove ammonia. A second wastewater stream (2nd WWT Stream) containing organic pollutants but being low in salts arises from the F-T process and is treated separately to allow recycling within the F-T process.

Layered double hydroxide and zirconium phosphate as ion exchangers for the removal of 'black crusts' from the surface of ancient monuments

Boccalon,Nocchetti,Pica,Romani,Casciola

supporting information, p. 2976 - 2985 (2018/03/06)

The chloride form of MgAl layered double hydroxide (hereafter MgAlCl) as an anion exchanger and the semisodic form of α-zirconium phosphate (hereafter ZrPNaH) as a cation exchanger are proposed as new cleaning agents for the removal of gypsum from ancient monuments. The ability of these exchangers to capture the calcium and sulphate ions of the gypsum powder was first investigated separately and then as a coupled system. MgAlCl/gypsum, ZrPNaH/gypsum and MgAlCl/ZrPNaH/gypsum mixtures were characterized by X-ray powder diffraction (XRD), field emission scanning electron microscopy (FE-SEM) and dispersive X-ray spectroscopy (EDX). ZrPNaH in the form of a wet paste exhibited a rapid uptake of calcium from gypsum powder via Na+ and H+/Ca2+ cation exchange. Gypsum powder was also successfully dissolved by a wet paste of MgAlCl by exploiting the Cl-/SO42- anion exchange reaction. However, the dehydration of the paste favoured the reprecipitation of a secondary gypsum that was characterized by lower crystallinity and smaller particle size than the pristine gypsum. The combination of wet MgAlCl and ZrPNaH showed a synergic effect on the dissolution of gypsum and partially prevented the reprecipitation of gypsum in the dry paste. Finally, a preliminary test of the removal of gypsum crust grown on a sandstone sample was performed.
