Description

2-Phosphonobutane-1,2,4-Tricarboxylic Acid used as water treatment PBTC
CAS No.: 37971-36-1
MF: C7H11O9P ?Molecular weight: 270.13
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.
Package:
Normally In 250kg net Plastic Drum, 1250kg IBC drum can also be used as required.
Safety Protection:
Acidity, Avoid contact with eye and skin, once contacted, flush with water
