Product Description

CAS 37971-36-1 2-Phosphonobutane-1,2,4-Tricarboxylic Acid 50% PBTC For Water Treatment

Product Description

2-Phosphonobutane-1,2,4-Tricarboxylic Acid (PBTC)

Description

2-Phosphonobutane-1,2,4-Tricarboxylic Acid (PBTC) is a highly effective phosphonate-based scale and corrosion inhibitor. It features excellent stability under high temperatures, high pH, and oxidizing conditions (e.g., chlorine treatment), making it ideal for industrial water treatment applications.

Specification

Parameter	Specification
Chemical Formula	C₇H₁₁O₉P
Appearance	Clear to slightly yellow liquid
Active Content (%)	≥ 50%
pH (1% aqueous solution)	1.5 - 2.5
Density (20°C, g/cm³)	1.28 - 1.35
Solubility	Completely soluble in water
Phosphorus Content (as P)	~7.5%

Features

✔ Excellent scale inhibition – Prevents calcium carbonate, calcium phosphate, and sulfate scales.
✔ High chlorine resistance – Stable in oxidizing environments (unlike many phosphonates).
✔ Broad pH range stability (up to pH 9.5).
✔ Synergistic with polymers & zinc – Enhances corrosion inhibition in cooling water systems.
✔ Low environmental impact – Phosphorus content lower than traditional phosphonates.

Applications

Cooling water treatment (open & closed-loop systems).
Boiler water treatment (scale & corrosion control).
Reverse osmosis (RO) antiscalant.
Detergent & cleaning formulations (metal ion sequestration).
Pulp & paper industry (dispersant for calcium control).

Packing & Storage

Packing: 25 kg, 200 kg plastic drums, or 1000 kg IBC totes.
Storage: Keep sealed in a cool, dry place (<40°C); avoid freezing.
Shelf Life: 24 months if stored properly.
