Product Description

CAS No. 37971-36-1

Molecular Formula: C7H11O9P

Molecular weight: 270.13

Structural Formula:

PBTC Chemical Properties :

PBTC is a low phosphoric acid content compound with the structural features of phosphoric and carboxylic acids. Its antiscale properties under high temperatures are far better than those in organophosphines, making it an ideal choice for scale and corrosion control. Additionally, it improves zinc salt solubility and exhibits good chlorine oxidation tolerance and composite synergy.

PBTC Chemical Specification:

Usage:

PBTC is a highly effective scale and corrosion inhibitor, making it a popular choice in circulating cool water and oilfield refill water systems. It can also be used as a chelating agent and metal detergent in lavation fields. Its excellent stabilizing properties for zinc salt make it ideal for high temperature, hardness, alkali, and concentration environments.

When used alone, the recommended dose is 5-15mg/L. However, it is usually combined with zinc salt, copolymer, organophosphine, imidazole, or other Water Treatment Chemicals to achieve better results.

PBTC Applications

PBTC is a high-performance scale and corrosion inhibitor with outstanding chemical and chlorine stability, ideal for severe cooling-water conditions.

Circulating cooling water at high temperature, high pH and high hardness
Systems running at high cycles of concentration
Programs using chlorine-based biocides

Dosage & Feed Guidance

Application	Typical dosage
Circulating cooling water	1–15 ppm (mg/L)

Its strong threshold effect and chlorine stability often allow lower dosing than other phosphonates in demanding systems, with good calcium tolerance. VCYCLETECH provides a tailored dosing program on request — email sales@vcycletech.com.
