Product Description

Product Description

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

CAS No.  37971-36-1
Molecular Formula:   C₇H₁₁O₉P            Molecular weight: 270.13
Structural Formula:
 

Properties:

PBTC 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:

Items	Index
Appearance	Clear, colorless to pale yellow aqueous solution
Active content %	49-51
Phosphorous acid(as PO3^3-)%	0.5 max
Phosphoric acid(as PO4^3-)%	0.2 max
Density (20ºC) g/cm^3	1.27 min
pH(1% water solution)	1.5~2.0
Fe, mg/L	10.0 max
Chloride mg/L	10.0 max

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 other Water Treatment Chemicals. When used alone, the dosage of 5-15mg/L is preferred.

Package and Storage:

200L plastic drum,IBC(1000L),customers' requirement. Storage for one year in shady room and dry place.

Safety Protection:

Acidity, Avoid contact with eye and skin, once contacted, flush with water.

Company Profile

Shandong XinTai Water Treatment Technology Co., Ltd. is a leading water treatment chemicals producer in China. Situated on the outer ring road of Zao Zhuang City, Shandong Province, the company benefits from a pleasant climate, beautiful scenery, and convenient transportation. Our product portfolio encompasses organic phosphonic series, organic phosphate salts, corrosion inhibitors, chelating agents, dispersants, RO membrane chemicals, etc., ranging from single to complex agents. These products are extensively applied in circulating water, boiler, and heating water systems across industries like steel & iron, petrochemical, power plants, and medical. To meet diverse demands, we've recently developed solid products such as high - pure and ordinary - grade organophosphoric acids and their sodium salts, as well as some polymer solid products. We operate a synthesis and application laboratory, which not only conducts research but also collaborates with clients on water quality analysis and treatment process planning. Sales Highlights: - Specialize in water treatment chemicals, positioning as a key workshop in the field. - Target intermediary buyers of water treatment chemicals rather than end - users. - Offer free services including water quality analysis, prescription screening, operation planning draft, and on - site supervision. - Provide new product development and trial - production services based on client orders. Quality Assurance: We hold the ISO9001/ISO18001/ISO45001 quality management system certificate, ensuring stable product quality.
