Molecular Formula: C7H11O9P Molecular weight: 270.13
Structural Formula:
Properties:
PBTCA 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. 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.

Usage:
PTBCA is a high efficient agent as scale and corrosion inhibitor. It 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. It 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 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.
