1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

Short Identity Section

Detailed Identification

Description:
BHMTPMP is a high-performance organophosphonate-based chelating and scale inhibition agent. It effectively controls the formation of carbonate and sulfate-based deposits while maintaining stable performance at high temperatures and over a wide pH range. The product has excellent water solubility and, thanks to its high calcium ion tolerance, provides reliable results under challenging water conditions. It is specifically used in industrial water systems, oilfield applications, and boiler systems for corrosion and deposit control.

20. SUMMARY AND CRITICAL WARNINGS

SUMMARY

BHMTPMP (Bis(Hexamethylene Triamine Penta(Methylene Phosphonic Acid))) is a high-performance organophosphonate-based chelating and scale inhibition agent. It effectively controls the formation of carbonate and sulfate-based deposits while maintaining stable performance at high temperatures and over a wide pH range. The product has excellent water solubility and, thanks to its high calcium ion tolerance, provides reliable results under challenging water conditions. It is specifically used in industrial water systems, oilfield applications, and boiler systems for corrosion and deposit control.

It appears as a dark amber liquid. Its active content is 43.0–48.0%, density is ≥1.20 g/cm³ (20°C), pH is ≤2.0 (1% solution), and molecular weight is 685.41 g/mol. It is soluble in water.

It is used in oilfield injection waters, production and reinjection water systems, open and closed circuit cooling systems, low and medium pressure boiler systems, deposit control systems, and hard water conditioning applications.
