Cas No. :37971-36-1
2-Phosphonobutane -1,2,4-Tricarboxylic Acid(PBTCA)
CAS No. 37971-36-1 Molecular formula: C7H11O9P Molecular weight: 270.13 Structural formula Properties PBTCA has low content of phosphoric and structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy. Specification Items Index Appearance Colorless or light yellow transparent liquid Active acid % 50.0-51.0 Phosphorous acid(as PO33-)% 0.5max Phosphoric acid (as PO43-)% 0.2max pH(1% water solution) 1.5~2.0 Chloride, ppm 10.0max Fe, ppm 10.0max Density (20℃)g/cm3 1.27min Usage PBTCA is a high efficient agent as scale and corrosion inhibitor. PBTCA is the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. PBTCA can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent. PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/l is preferred. Package and storage 200L plastic drum,IBC(1000L),customers’ requirement. Storage for one year in shady room and dry place. Safety protection Acidity, avoid contact with eye and skin, once contacted, flush with water.
