Description

Sodium Trihydrogen [[[3-(1,3-Dimethylbutoxy)Propyl]Imino]Bis(Methylene)]Bisphosphonate is a specialized organophosphonate compound designed for high-performance scale and corrosion inhibition in demanding aqueous systems. This advanced phosphonate chemistry offers superior stability and chelating power compared to traditional phosphates, making it a critical component for protecting industrial equipment and ensuring process efficiency. It is primarily utilized by water treatment formulators and chemical suppliers serving the oil & gas, industrial cleaning, and cooling water treatment markets where control of calcium carbonate and other mineral scales is paramount.

Application

• Industrial Water Treatment: A key active ingredient in formulations for scale and corrosion inhibition in recirculating cooling water systems, boilers, and reverse osmosis membranes.
• Oilfield Chemistry: Used in squeeze treatments and production chemicals to prevent scale deposition in downhole and topside equipment, enhancing oil recovery and flow assurance.
• Industrial & Institutional (I&I) Cleaning: Serves as a highly effective sequestrant and builder in acidic and alkaline detergent formulations for metal cleaning and dairy/brewery CIP processes.
• Pulp & Paper Processing: Acts as a chelant and dispersant to control scale in digesters, bleach plants, and paper machines, improving operational efficiency and product quality.
• Textile Processing: Employed as a stabilizer and sequestering agent in peroxide bleaching baths and dyeing processes to prevent metal-ion catalyzed degradation.
• Personal Care: Functions as a chelating agent in certain cosmetic and personal care formulations to enhance stability and shelf life.

Quality Control

Our production of Sodium PBTC adheres to stringent quality management protocols. Every batch undergoes rigorous analytical testing, including assay by titration and identification by FT-IR, to ensure it meets precise compositional and performance specifications. Certificates of Analysis (COA) documenting purity, active content, pH, and density are provided with each shipment to guarantee traceability and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which may lead to caking or reduced efficacy.
