CAS No. 40372-66-5 Dequest 7006
Molecular Formula: C7H7O9P·Na4 Molecular weight: 358
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.
