• Recent ClinicalTrials: Effect of Sodium Thiosulfate on Nephrotoxicity of Cisplatin Intraperitoneal Heat-perfusion Chemotherapy
• Recent EU Clinical Trials: A Randomised controlled trial to compare efficacy and tolerability of Plenvu? and Picoprep? as cleansing agents before colonoscopy
• Inhalation Risk: Evaporation at 20 °C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly.
• Effects of Short Term Exposure: Ingestion could cause effects on the gastrointestinal tract.
• Activator in Alkali Activation Process: Sodium sulfate (Na2SO4) is commonly used as an activator in alkali activation processes, particularly in the production of alkali-activated composites (AACs). The type and concentration of the alkali activator(s), including sodium sulfate, play a crucial role in determining the properties of AACs.
• Role in Concrete Binders: Sodium sulfate is considered an eco-friendly activator for alternative binders to Ordinary Portland Cement (OPC). Utilization of activators with weak alkalinity, such as sodium sulfate, calcium hydroxide, or calcium oxide, has gained attention due to practical considerations in producing alkali-activated materials-based binders.
• Impact on Geopolymerization: Sodium sulfate affects the geopolymerization process and properties of one-part geopolymers. It delays the geopolymerization process and reduces compressive strength, particularly at early curing stages. However, it can decrease the cost of one-part geopolymers without sacrificing environmental friendliness or mechanical properties.
• Optimization in Alkali-Activated Geopolymers: Sodium sulfate has an optimal mass ratio in alkali-activated geopolymers, which varies with the water-to-binder ratio. Higher water content adversely affects alkali activation and microstructural properties, but the addition of sodium sulfate can mitigate these effects. Higher concentrations of sodium sulfate promote the formation of N-A-S-H gels and improve pore structure integrity, ultimately enhancing the strength of geopolymers.

Technology Process of Sodium Sulfate

There total 566 articles about Sodium Sulfate which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 1.0%

sulfuric acid (7664-93-9) + sodium nitrite (7632-00-0) → sodium nitrate (7631-99-4) + nitrogen(II) oxide (10102-43-9) + sodium sulfate (7757-82-6) + dinitrogen monoxide (10024-97-2)

Guidance literature:

byproducts: H2O, N2; NO collection, storing over dil. sodium hydroxide soln. (NO2 impurity elimination);

Reference yield:

Guidance literature:

With water; exclusion of oxygen, excess of thiosulfate, too;

Reference yield:

Iodine monochloride (7790-99-0) + sodium sulfite (7757-83-7) → hydrogenchloride (7647-01-0,15364-23-5) + hydrogen iodide (10034-85-2) + sodium sulfate (7757-82-6)
