2-Phosphonobutane-1,2,4,-tricarboxylic acid (PBTC)
CAS No.: 37971-36-1
Molecular Formula: C7H11O9P
Synonyms: Dequest 7000, PBTC, Phophonobutane Tricarboxylic Acid

PBTC is a very effective scale inhibitor used in various industrial applications. Due to its higher performance properties it is a very cost effective inhibitor compared to standard Phosphonates such as HEDP/ATMP. This is mainly due to superior stability to chlorine, bleach and bromine. In cooling water PBTC performs well at high PH or temperatures. It further shows high effectiveness in high alkaline solutions such as industrial cleaners.

Applications:
Cooling water systems / industrial water treatment
Industrial detergents
Disinfectants
Liquid dishwashing concentrates
Metal surface treatment as corrosion inhibitor for steel
Retardant in concrete
Sequestering agent in textile auxiliaries

Usage:
PBTC is a high efficient agent as scale and corrosion inhibitor. PBTC is the excellent stabilizer for zinc salt. 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. 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.
PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and otherWater Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

Pacakge and Storage:
