| Chemical | PBTCA (2-Phosphonobutane -1,2,4-Tticarboxylic Acid) |
| CAS No. | 37971-36-1 |
| General Introduction | PBTCA has low content of phosphoric, its 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. |

| Core Performance Advantages | |
|---|---|
| 1. Highly Effective Scale Inhibition |
- Scale inhibition rate reaches 98% against calcium carbonate and calcium phosphate scale (at a dosage of 5-15 mg/L). - Maintains stable scale inhibition even under high temperatures (below 120°C), high hardness, and high alkalinity. - Can increase circulating water concentration to over 7 times, reducing water waste. |
| 2. Excellent Corrosion Inhibition |
- As an excellent stabilizer for zinc salts, it stabilizes zinc ions at pH 7.0-9.5, enabling alkaline operation of zinc-containing formulations. - Forms a protective film on metal surfaces, reducing corrosion rates and extending equipment life. |
3. Oxidation and Chlorine Resistance |
- As an excellent stabilizer for zinc salts, it stabilizes zinc ions at pH 7.0-9.5, enabling alkaline operation of zinc-containing formulations. - Forms a protective film on metal surfaces, reducing corrosion rates and extending equipment life. |
4. Low Phosphorus Environmental Protection |
- Low phosphorus content meets environmental requirements and reduces the risk of eutrophication. |
| PBTC Application | |
|---|---|
| 1. Industrial Water Treatment |
- Circulating Cooling Water Systems: Acts as a scale and corrosion inhibitor to prevent scale formation and equipment corrosion. - Oilfield Water Injection: Purifies water quality, prevents scaling and corrosion in pipes and equipment, and improves recovery efficiency. - Boiler Water Treatment: Reduces scale accumulation in boilers and improves thermal efficiency. |
| 2. Textile and Printing Industry |
- Treats dyeing and printing water to prevent uneven dyeing or color variations caused by metal ions. - Improves dyeing and printing uniformity and enhances product quality. |
|
3. Papermaking Industry |
- Controls metal ions and minerals in water to prevent scale formation. - Reduces metal contamination in pulp production and improves paper quality. |
|
4. Detergents and Cleaners |
- Acts as a chelating agent and dispersant to remove stains and prevent calcium and magnesium ions in water from reacting with active ingredients in detergents. |
|
5. Metal Surface Treatment |
- Prevents oxidation and corrosion on metal surfaces and provides protection. |
|
6. Other Applications |
- Water-soluble fertilizers: Chelates metal ions in water, preventing precipitation and improving fertilizer utilization. - Pesticide formulations: Maintains pesticide stability and prevents metal ions from disrupting the molecular structure. - Chemical production: Controls metal ions in water, preventing adverse reactions and ensuring production stability. |
