CAS No. 37971-36-1 Dequest 7000
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 agents. 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.
