Molecular Formula: C7H7O9P·Na4 Molecular weight: 358
Structural Formula:
Properties:
PBTCA·Na4 has low content of phosphoric, its structure
contains both phosphonic acid and carboxylic acid
group, which enable its good scale and corrosion
inhibition properties. Its scale inhibition property
under high temperature is far better than that of
organophosphines. PBTCA·Na4 can improve the solubility
of zinc salt, has good chlorine oxidation tolerance and
good composite synergy. The solid state is easy
deliquescence.

Usage:
PBTCA·Na4 is the widely used and
high effective agent as composite scale and corrosion
inhibitor, it is also the excellent stabilizer for zinc
salt. PBTCA·Na4 is used as scale and corrosion
inhibitor in circulating cool water system and oilfield
refill water system, especially used together with zinc
salt and copolymer. PBTCA·Na4 can be used in situations
of high temperature, high hardness, high alkaline and
high concentration index, PBTCA·Na4 is used as
chelating agent and metal detergent in lavation fields.
PBTCA·Na4 is usually used together with zinc salt,
copolymer, organophosphine, imidazole and other water
treatment agents.
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.
