Product Name:    

2-Phosphonobutane-1, 2, 4-Tricarboxylic Acid (PBTC)






PBTC (similar to Dequest 7000) is a kind of phosphoryl polycarboxylic acid, a part of corrosion scale inhibitor, it can be mixed with water by any proportion, stable chemical properties. It belongs to hazardous article Class 8.1. PBTC  has structural features of both phosphoric acid and carboxylic acid group, which enable its excellent scale and corrosion inhibition properties. Its antiscale property under high temperature is far better than that of organophosphines. PBTC  can improve zinc solubility, has good chlorine oxidation tolerance and good composite synergy. 


CAS No. 37971-36-1

Character and Advantage

PBTC  can chelate with Fe, Cu, and Zn ions to form stable chelating compounds. It can dissolve the oxidized materials on these metals’ surfaces. It is hard to be hydrolyzed, and hard to be decomposed under ordinary light and heat conditions. PBTC  can react with metal ions in water system to form chelating complex, it does not reflect metal properties. Therefore, PBTC  can efficiently inhibit scale formation, calcium carbonate and calcium sulfate in particular, and it has good antiscale and visible threshold effects.


PBTC  is a high efficient agent as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt. PBTC  is widely used in circulating cool water system and oilfield refill water system as scale and corrosion inhibitor, suitable to composite with zinc salt and copolymer. PBTC  can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, it is used as chelating agent and metal detergent.





1)      Oilfield reinjection water system: as scale and corrosion inhibitor.

2)      RO system: as scale inhibitor.

3)      Circulating cool water system: as scale and corrosion inhibitor.

4)      Woven & dyeing industries: as chelating dispersant.


Package and Storage


Package and Storage Recommendation


1)      Normally in 200L drum or IBC (1000L) can be used as required.

2)      Storage for 24 months in room shady and dry place.
