For industrial professionals, selecting the right chemical raw materials is critical for ensuring consistent product quality and operational efficiency. Phosphonobutane Tricarboxylic Acid (PBTC) is a prime example of a specialty chemical where understanding key specifications is essential. As a leading China manufacturer and supplier of PBTC, we are committed to transparency and providing our clients with high-quality products that meet rigorous standards.

PBTC, identified by CAS No. 37971-36-1, is primarily used as a scale and corrosion inhibitor in water treatment, but its performance is directly linked to its purity and adherence to specific parameters. When you buy PBTC, paying attention to the following specifications, often detailed in a Certificate of Analysis (COA) provided by a reliable PBTC supplier, is crucial:

  • Appearance: High-quality PBTC is typically a colorless to light yellow transparent liquid. Any significant deviation in color or clarity could indicate impurities or degradation.
  • Active Content: This refers to the percentage of PBTC in the solution, usually around 50% for common industrial grades. Ensuring the specified active content guarantees the product's efficacy.
  • Phosphorous Acid (as PO₃³⁻) and Phosphoric Acid (as PO₄³⁻): Lower levels of these by-products are desirable. High concentrations can indicate incomplete reaction or side reactions during synthesis, potentially affecting performance and environmental impact. Reputable manufacturers strive to minimize these impurities.
  • pH Value (1% water solution): PBTC is an acidic compound, and its pH typically falls within a range of 1.5 to 2.0. This is a key indicator of its chemical nature and can influence its compatibility with other formulation components.
  • Iron (Fe) and Chloride (Cl⁻) Content: Low levels of metal impurities like iron and chloride are important, as they can sometimes contribute to corrosion or interfere with other treatment agents. Manufacturers aim to keep these well below specified limits (e.g., ≤10 ppm for Fe and ≤10 ppm for Cl⁻).
  • Density (20℃): The density, typically around 1.27 g/cm³, is another physical parameter that confirms the product's composition and concentration.

As a leading China manufacturer, we invest heavily in advanced production processes and quality control to ensure our PBTC consistently meets these critical specifications. Understanding these parameters helps procurement managers and R&D scientists make informed decisions when comparing PBTC price and quality from different suppliers. Our aim is to provide not just a product, but a guarantee of performance and reliability for your industrial applications.
