Product Description
PBTC is an organophosphonic acid compound exhibiting excellent sequestration of metal ions at stoichiometric concentration and threshold inhibition of metal salt precipitation at sub-stoichiometric concentrations. The ability of PBTC to deflocculate or disperse solid particles combined with its temperature and hydrolytic stability makes it a versatile ingredient for applications requiring efficient metal ion (like Fe/Fe) control.
2-PHOSPHONOBUTANE-1,2,4-TRICARBOXYLIC ACID (PBTC)
PBTC is an organophosphonic acid compound exhibiting
excellent sequestration of metal ions at stoichiometric concentration and
threshold inhibition of metal salt precipitation at sub-stoichiometric concentrations. The ability of
PBTC to
deflocculate or disperse solid particles combined with its temperature and hydrolytic stability makes it a versatile ingredient for applications requiring efficient metal ion (like Fe/Fe) control.
Key Characteristics and Applications:
- Scale and Corrosion Inhibition: PBTC acts as a threshold inhibitor for carbonate, sulfate, and phosphate scales, and as a corrosion inhibitor for carbon steel.
- High Stability: It is highly stable under high temperatures and high pH conditions.
- Chlorine Tolerance: It shows excellent tolerance towards chlorine and hypo-chlorites, often used in systems with high oxidation demands.
- Applications: It is extensively used in industrial cooling water treatment, oilfield water injection systems, and industrial/institutional cleaners.
- Synergy: It works well in combination with other water treatment chemicals like zinc salts and copolymers
Chemical Properties:
- Formula: C7H11O9P
- CAS Number: 37971-36-1
- Appearance: Usually supplied as a 50% aqueous solution, which is a colourless to light yellow transparent liquid.
- Performance: It is known to be a better chelating agent than others, with lower phosphorus content for eco-friendly applications.
Safety and Handling:
PBTC is acidic and, at 50% concentration, can cause severe skin burns and eye damage. Proper protective equipment (gloves, goggles) should be used when handling.
