PBTC/PBTCA (CAS37971-36-1)
Full Name: 2-Phosphonobutane -1,2,4-TricarboxylicAcid
CAS No.: 37971-36-1
Molecular Formula: C7H11O9P
Molecular Weight: 270.13
Properties
PBTC has a low phosphorus content. Because it has the structural characteristics of phosphoricacid and carboxylic acid, PBTC offersbetter anti-scale and corrosion inhibitionfunctions than commonly used organic phosphonic acids. Additionally,PBTCA is resistant to chlorine oxidation and can greatly improve thesolubility of zinc. It can be used in harsh conditions (high temperature, highalkali, etc.)
Applications
1. PBTCA is widely used for anti-scale and corrosion inhibition applications in circulating cooling water systems and oilfield re-injection water systems.
2. PBTC is ideal for use as a stabilizer for zinc salt.
3. It can also be used as a chelating agent or metal cleaning agent.
