• Effects of Short Term Exposure: The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion.
• Laxative and Electrolyte Replacement: Trisodium phosphate (TSP) is utilized as a laxative and for electrolyte replacement purposes due to its basic properties and ability to provide reusability in such applications.
• Catalytic Applications: Trisodium phosphate finds application in catalysis, particularly in reactions such as glycerol carbonate synthesis, synthesis of 尾-hydroxyl ketone, and methanolysis. Its alkali property makes it suitable for catalyzing transesterification reactions in biodiesel production, yielding high biodiesel yields under mild reaction conditions.
• Inorganic Compound: Trisodium phosphate is an inorganic compound characterized by its crystal structure containing three sodium atoms and a phosphate group. Apart from its medicinal uses, it catalyzes various chemical reactions.
• Crosslinker: Trisodium phosphate (TSP) is selected as a crosslinker due to its single phosphate donation, which prevents excessive aggregation and yields stable and homogeneous systems. This property makes it suitable for various applications requiring crosslinking.
• Depressant in Mineral Processing: In mineral processing, TSP serves as a depressant, reacting with Mg2+ ions to form Mg3(PO4)2. This reaction facilitates the replacement of adsorbed Mg(OH)2 precipitates on sulfide minerals surfaces, potentially improving the efficiency of mineral separation processes.
• Microbial Reduction: Trisodium phosphate, in combination with other substances like acetic acid, lactic acid, and ascorbic acid, has been reported to significantly reduce microbial loads on meat surfaces. It exhibits bactericidal and bacteriostatic effects, making it useful for food sanitation purposes.
• Chicken Decontamination: Trisodium phosphate is employed for chicken decontamination, particularly against Campylobacter contamination, a common issue in poultry. Its antimicrobial properties contribute to reducing microbial contamination on chicken surfaces.
• Boiler pH Control: In industrial applications, trisodium phosphate is sometimes added to boilers for pH control purposes, indicating its versatility across various sectors beyond chemical synthesis and food sanitation.
