Frequently Asked Questions
What is the primary industrial sodium hydrosulfite use?
The primary industrial sodium hydrosulfite use is as an efficient reducing bleaching agent within the textile sector for vat coloring processes (including indigo reduction) and inside the pulp and paper industry. It also plays an important role in industrial water treatment and purification operations.
What is the difference between sodium hydrosulfite or sodium dithionite?
Chemically, there is no technical difference between sodium hydrosulfite or sodium dithionite; both terms reference the identical reducing salt compound with the stable chemical structure Na2S2O4. While sodium dithionite is widely recognized as the standard IUPAC name, sodium hydrosulfite is traditionally used in B2B chemical trading markets.
What is the standard purity of sodium dithionite 85?
The primary commercial grade manufactured for regular distribution is known as sodium dithionite 85, which specifies a guaranteed active compound concentration of 85% minimum. This industry-standard format offers ideal storage stability and cost-effective reduction capacity for major manufacturers.
What are the core parameters like sodium hydrosulphite density and solubility in water?
Essential specifications for high-quality technical batches include a solid sodium hydrosulphite density parameter of around 2.38 g/cm³ and an optimized sodium hydrosulphite solubility in water measuring roughly 250 g/L at 20 C. It generally exhibits a clean white powder appearance.
How can I access technical documents such as the sodium hydrosulphite tds?
Industrial procurement teams can easily download the official sodium hydrosulphite tds (Technical Data Sheet), detailed batch Certificate of Analysis (COA), and global Safety Data Sheets (SDS) by communicating directly with our compliance cell at [email protected].
What role does zinc play regarding sodium hydrosulphite zn compounds?
In manufacturing workflows, traditional production synthesis routes implement the zinc dust method, technically referred to as the sodium hydrosulphite zn reduction route. This process treats sulfur dioxide using zinc particles to formulate a high-yield product with minimal mineral residues.
How do you check the active wholesale sodium hydrosulfite price in India?
The operational sodium hydrosulfite price fluctuates regularly based on raw material components, aggregate volume demands, and logistics routes. Buyers can get instantaneous, factory-direct quotes by reaching out to the DPRJ Universal commercial desk.
