Quotation

CAS No.: 37971-36-1

Molecular Formula: C7H11O9P

Molecular weight: 270.13

Structural Formula:

pbtc 50

Properties:

PBTC 50 has a low content of phosphoric and 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. PBTC 50 can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Usage:

PBTC 50 is a high efficient agent as scale and corrosion inhibitor. PBTC 50 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. PBTC 50 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.

PBTC 50 is usually used together with the zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/l is preferred.

Package and Storage:

200L plastic drum, IBC (1000L), customers’ requirement. Storage for one year in a shady room and dry place.
