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. 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:
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, 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.
