CAS No. 37971-36-1
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:
PBTCA
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:
Normally In 250kg net Plastic Drum, IBC
drum can also be used as required. Storage for one year
in room shady and dry place.
Safety Protection:
Acidity, Avoid contact with eye and skin,
once contacted, flush with water.
