2-Phosphonobutane -1,2,4-Tricarboxylic Acid (PBTCA) CAS NO.37971-36-1

Founded in 2003, Nine Continent Company (hereinafter referred to as NCC) has set up three major production bases in China, headquartered in the BioBay of Suzhou Industrial Park. Suzhou is a very beautiful city with a long history, convenient transportation (only 20 minutes' drive from Suzhou to Shanghai) and many big international enterpries.

NCC’s rapid and stable development enables it to become a leading manufacturer of water treatment chemicals in China, with a turnover of RMB260 million in 2014 in domestic market. The product families include organic phosphonic series, organic phosphate salts, polycarboxylic antiscalant, corrosion inhibitors, chelating agents, dispersants, biocide, algicide and etc., covering wide ranges from single to complex agents. The products are widely used in circulating water system, boiler and heating water system in fields such as steel & iron, petrochemical, power plant, RO systems, textiles and medical industries.

Production Base

NCC owns a 1500-square-meter nanotechnology R&D center located in the BioBay of Suzhou Industrial Park, equipped with such technical laboratories as R&D laboratories, application laboratories, coating room, constant temperature and humidity room, printing room, electron microscopy room and etc. The R&D center is also equipped with more than 50 instruments including R&D instruments, wet-end instruments, coating instruments, printing instruments, physical property detecting instruments, particle size instruments and electron microscopy instruments, with a total value of RMB8 million. NCC’s R&D has come up to the same international advanced level as laboratories of some leading chemical companies as BASF, Ashland and Akzo Nobel.

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

CAS NO: 37971-36-1

Molecular Formula: C₇H₁₁O₉P　　

Molecular Weight: 270.13

Structural Formula:

Properties:

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.

Specification: HG/T 3662-2000

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. In lavation fields, it is used as chelating agent and metal detergent.

PBTCA is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water rreatment chemicals. When used alone, the dosage of 5-15mg/L is preferred.

Safety:

Acidity. Avoid contact with eye and skin. In case of contact, flush with water immediately.

Package and storage:

25kg/250kg net in plastic drum.

Storage for twelve months in shady room.
