Manufacturing Process

This report comprises a thorough value chain evaluation for Sodium Hypophosphite manufacturing and consists of an in-depth production cost analysis revolving around industrial Sodium Hypophosphite manufacturing.

• Production via Direct Reaction and Crystallisation: The feedstock for this process includes white phosphorus (P4), sodium hydroxide (NaOH), and carbon dioxide (CO2). The manufacturing process of sodium hypophosphite involves a direct reaction between white phosphorus and sodium hydroxide. In this method, white phosphorus is reacted with concentrated sodium hydroxide solution in the presence of carbon dioxide gas. When white phosphorus is added to the caustic soda solution, it starts to break down and form hypophosphite ions. The reaction is highly exothermic, and the reactor is heated and stirred under controlled conditions to ensure that the reaction proceeds smoothly. Carbon dioxide plays a supporting role in maintaining the right conditions for the reaction. The solution is then concentrated (e.g., by evaporation) and subjected to crystallisation (e.g., by cooling) to obtain solid sodium hypophosphite crystals. The crystals are then separated, washed, and dried to obtain pure sodium hypophosphite as the final product.
