Zinc Formaldehyde Sulfoxylate (ZFS), with the chemical formula Zn(HSO2CH2O)2, is a key reducing agent utilized predominantly in the textile industry for vat dyeing, printing processes, and bleaching of natural fibers. Its unique properties allow for effective bleaching at lower temperatures, making it a preferred choice for delicate fabrics. HighMountainChem offers top-grade Zinc Formaldehyde Sulfoxylate, designed to meet the rigorous demands of modern textile processing, ensuring superior quality and environmental compliance.
Zinc formaldehyde sulfoxylate has a wide range of applications in scientific research:
● Target of Action
Zinc formaldehyde sulfoxylate, also known as Parolite, is primarily used as a discharge agent in textile printing and as a redox catalyst in the manufacturing of polymers for adhesives. It interacts with the dye molecules in the textile and the monomers in the polymerization process.
● Mode of Action
Zinc formaldehyde sulfoxylate acts as a reducing agent in its applications. In textile printing, it breaks the bonds of the dye molecules, causing them to lose their color. In the polymerization of ethylene vinyl acetate (EVA), it acts as a redox catalyst, facilitating the reaction by transferring electrons.
● Biochemical Pathways
In these reactions, Zinc formaldehyde sulfoxylate can donate electrons, thereby altering the state of other molecules in the pathway. ● Pharmacokinetics Zinc formaldehyde sulfoxylate is very soluble in water, but insoluble in alcohol and decomposes in acid. This solubility profile affects its bioavailability in different environments.
● Result of Action
The primary result of Zinc formaldehyde sulfoxylate’s action is the alteration of the chemical structure of other molecules. In textile printing, this results in the discharge of color from the fabric. In the polymerization of EVA, it helps in the formation of the polymer chains.
● Action Environment
The action of Zinc formaldehyde sulfoxylate is influenced by environmental factors such as pH and temperature. It is very soluble in water, which allows it to be easily distributed in aqueous environments. It decomposes in acid, which can limit its stability and effectiveness in acidic conditions. Its action can also be affected by temperature, as it decomposes at temperatures above 90 degrees Celsius.
It is known that it is a strong reducing agent, suggesting that it may participate in redox reactions in biochemical systems.
Given its role as a reducing agent , it may influence cell function by participating in redox reactions, which are crucial for many cellular processes. These could potentially impact cell signaling pathways, gene expression, and cellular metabolism.
As a reducing agent , it may interact with various biomolecules in the cell, potentially influencing enzyme activity and gene expression.
Synthetic Routes and Reaction Conditions: Zinc formaldehyde sulfoxylate can be prepared from any salt of formaldehyde sulphoxylic acid whose cation forms a water-insoluble fluosilicate, such as potassium and calcium.
The ordinary process for the manufacture of anhydrous zinc formaldehyde sulfoxylate involves the following steps:
Zinc dust suspended in water is converted to zinc hydrosulphite by reacting with sulfur dioxide.
The resulting zinc hydrosulphite solution is treated with formaldehyde to obtain a mixture of zinc formaldehyde sulfoxylate and zinc formaldehyde bisulphite.
Industrial Production Methods: In industrial settings, zinc formaldehyde sulfoxylate is produced by reacting zinc oxide with formaldehyde and sodium formaldehyde sulfoxylate in an aqueous solution. This method ensures the production of high-quality zinc formaldehyde sulfoxylate suitable for various applications.
