Synthesis of 2-Phosphonobutane-1, 2, 4-Tricarboxylic Acid

2-Phosphonobutane-1,2,4-tricarboxylic acid is(PRTC) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. Phosphonocarboxylates as a member of organophosphorus compounds have C-P and P-O bonds in their structures. PBTC is mainly used as carbonate scale inhibitor (CaCO3), sulphate scale inhibitor (CaSO4), corrosion inhibitor of low alloyed steel, effective and well applicable in alkaline hard-waters, excellent resistance against chlorine, usable in detergents and cleaning agents and also a unique stabilizer of bleaching substances. In the present work PBTC is synthesized using dimethyl hydrogen phosphite, dimethyl maleate and methyl acrylate, overall yielding 86.5% product.
