2-Phosphonobutane -1,2,4-Tricarboxylic Acid
(PBTCA)
CAS No. 37971-36-1
Molecular Formula: C7H11O9P Molecular weight: 270.13
Structural Formula:
Properties:
PBTC has low content of phosphoric, has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. PBTC’santiscale property under high temperature is far better than that of phosphonates. Phosphonate PBTC can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Usage:
Phosphonate PBTC is a high efficient agent as scale and corrosion inhibitor. PBTC 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. PBTC 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.
PBTC is usually used together with zinc salt, copolymer, phosphonates, imidazole and otherWater Treatment Chemicals. 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.
