PBTC (2-Phosphonobutane 1,2,4-tricarboxylic acid)
| CAS No. : 37971-36-1 | Molecular Weight: 270 |
| Molecular Formula: C7H11O9P | Brand Name: ZEELCHEM |
Product Overview:
PBTC is a low-phosphorus chemical that incorporates organophosphonate, known for its outstanding capability as a threshold scale inhibitor. This means that even at very low concentrations (measured in ppm), it effectively inhibits the formation of scales from carbonates, sulfates, and phosphates based on the hardness of the water.
- It exhibits strong chelation properties for heavy metals.
- It is a milder complexing agent for metals compared to EDTA, which helps to prevent the re-mobilization of heavy metals from sediments.
- It maintains excellent stability in the presence of chlorine and hypochlorites when bromine is present, unlike many other phosphonates that degrade quickly.
- Its impressive thermal stability across a variety of pH levels allows it to remain effective even at elevated pH and temperature conditions.
In addition, it has dispersion capabilities, as its anions can be adsorbed by inorganic particles in water, enhancing its dispersive properties.
Finally, it serves as an effective corrosion inhibitor for carbon steel, making it an essential part of all organic water treatment programs.
Applications:
- Industrial cooling water treatment.
- Industrial and institutional cleaners (I & I formulations)
- Disinfectants
- Liquid dishwashing and detergents
- Metal surface treatment
- Sequestering agent in textile auxiliaries
- Hypochlorite stabilization
