CAS No. 40372-66-5
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 organophosph-ines.
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 Chemicals.
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.
