In the realm of industrial water treatment, the quality of chemicals used directly dictates the efficacy and reliability of the entire system. For 2-Phosphonobutane-1,2,4-Tricarboxylic Acid (PBTC), a cornerstone for scale and corrosion inhibition, understanding its specifications and the analytical methods used to ensure them is paramount. As a leading manufacturer, we prioritize transparency and precision in our PBTC production.

PBTC, with its CAS number 37971-36-1, is typically supplied as an aqueous solution, often around 50% active content. Key specifications that users should verify when looking to buy PBTC include: appearance (clear, colorless to pale yellow transparent liquid), active acid content (typically 49.0-51.0%), and limits for impurities such as phosphorous acid (as PO33-) and phosphoric acid (as PO43-). Low levels of these related acids are indicators of a well-synthesized product. For instance, a maximum of 0.8% phosphorous acid and 0.5% phosphoric acid (or even lower, like 0.2% for phosphoric acid) are commonly specified.

Other critical parameters include pH (usually 1.5-2.0 for a 1% solution), iron content (e.g., ≤ 20.0 ppm), and chloride content (e.g., ≤ 10.0 ppm). These specifications ensure the PBTC is suitable for its intended applications without introducing detrimental elements into the water system. When comparing PBTC pricing, it's vital to ensure that the quoted product meets these essential quality benchmarks. A lower price without comparable specifications might lead to inferior performance and higher long-term costs.

The analysis of PBTC quality often involves sophisticated techniques to confirm both purity and structural integrity. Nuclear Magnetic Resonance (NMR) spectroscopy, particularly carbon-13 NMR, is invaluable for identifying the unique molecular structure of PBTC and verifying its presence. Phosphorus-31 NMR is equally important, as it can detect and quantify residual unreacted raw materials or by-products that might compromise the PBTC's scale inhibition and dispersion properties. A high proportion of the PBTC phosphorus signal compared to total phosphorus signals indicates good product purity. This is why sourcing from a reliable PBTC supplier who employs rigorous quality control is essential.

We, as a dedicated manufacturer, utilize these advanced analytical methods to guarantee that our PBTC meets the highest industry standards. We are committed to providing our clients with detailed Certificates of Analysis for each batch, ensuring confidence in the product's performance. For those seeking the best water treatment solutions, understanding these specifications and the importance of quality-assured PBTC is the first step.
