【CAS】 37971-36-1           Dequet 7000

Molecular formula: C₇H₁₁O₉P                          Relative molecular mass: 270.13

I. Product Property

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.

II.

III. Purpose

PBTCA 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.

IV. Application Scope and Usage

PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When it is used alone, the dosage of 5-15mg/L is preferred.

V. Package and Storage

It is usually packed in 30kg or 250kg plastic drum and stored for 12 months in shady and dry place under room condition.

VI. Safety Protection:

This product is in acidity. Avoid contact with eye and skin. Rinse with plenty of water shortly after being bodily stained.
