2-phosphonobutane -1,2,4-tricarboxylic Acid (Pbtca) By Nine Continent Biotechnology (Suzhou) Co., Ltd

We are engaged in manufacturing, exporting and supplying excellent quality 2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA) to our valuable clients.
CAS No. 37971-36-1
Other Names: 1,2,4- three -2- carboxylic acid phosphonic acid butane, 2-Phosphonobutane-1,2,4-tricarbonic acid; PBTC
Molecular Formula: C7H11O9P
Molecular Weight: 270.13

PBTCA has low content of phosphoric, 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. It can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Usage:
PBTCA is one of the most effective and widely used agents as scale and corrosion inhibitor. It is the excellent stabilizer for zinc salt as well. It 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. It can be used under conditions of high temperature, high hardness, high alkali and high concentration index.
