HIGH QUALITY PBTC and PBTCA CAS: 37971-36-11

2-Phosphonobutane-1,2,4-tricarboxylic Acid (PBTC), Cas:37971-36-1, is widely used as a corrosion and scale inhibitor in circulating cooling water systems and oilfield water injection systems. It is particularly suitable for use in combination with zinc salts and copolymers, and can be used in high-temperature, high hardness, high alkali, and high concentration operation scenarios. PBTCA can be used as a chelating agent and metal cleaning agent in the washing industry.

PBTCA Cas:37971-36-1 is generally used in combination with other water treatment agents such as zinc salts, copolymers, organic phosphines, azoles, etc; If used alone, the dosage should be 5-15mg/L.

PBTCA Cas:37971-36-1 is a colorless or light yellow transparent liquid. Relative density (20 ℃) 1.275. Freezing point -15 ℃. Has excellent scale and corrosion inhibition performance. Acid resistant, alkali resistant, and oxidant resistant. When pH>14, it still does not hydrolyze and has good thermal stability.

PBTCA Cas:37971-36-1 is used as a corrosion and scale inhibitor for industrial water treatment. This product has excellent chelating ability with Ca2+, Zn2+, Cu2+, Mg2+ions. Suitable for use in Chemicalbook within the pH range of 7.0-9.5. Can operate under high temperature, high hardness, and high alkalinity conditions. It can increase the concentration factor of circulating cooling water to over 7.
