Sodium Formaldehyde Solfoxylate, Synthesis, Optimization and Performance Evaluation

Reducing agents in various industries have different applications. Rongalite or sodium formaldehyde sulfoxylate (SFS) is a compound that is used as industrial bleaching agent and reducing agent. Due to the wide range of sodium formaldehyde sulfoxylate applications, such as reducing agent for redox-catalyzed polymerization, stripping and discharge agent for textiles, reducing agent in vat dying, bleaching agent for molasses, antioxidant in pharmaceuticals and green reagent in organic synthesis, research activities have been done on the synthesis of this material. [1], [2], [3], [4]. We which to report synthesis of this substance was selected and optimized with industrial approach and synthesized in two steps. In the first step, Zinc dithionite was synthesized as an intermediate and in the second step, sodium formaldehyde sulfoxylate was obtained. Optimization of temperature, solvent has also been studied.
