Specification :

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

CAS No. 37971-36-1
Dequest 7000
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. PBTCA can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.

Specification of PBTCA:
Appearance of PBTCA:Colorless or light yellow transparent liquid
Active acid of PBTCA: 50.0 percent min
Phosphorous acid of PBTCA (as PO33-): 0.8percent max
Phosphorous acid of PBTCA (as PO43-): 0.5 percentmax
Density of PBTCA (20centigrade): 1.27 g/cm3 min
pH of PBTCA (1percent solution): 1.5~2.0

Usage of PBTCA:
PBTCA is a high efficient agent as scale and corrosion inhibitor. PBTCA is the excellent stabilizer for zinc salt. PBTCA 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. PBTCA can be used in situations of high temperature, high hardness, high alkali and high concentration index. In lavation fields, PBTCA is used as chelating agent and metal detergent.
PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

Package and Storage of PBTCA:
Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for one year in room shady and dry place.
