分子式  C₇H₁₁O₉P                     相对分子质量：270.13

结构式

一、产品性能：

PBTCA含磷量低，由于它具有膦酸和羧酸的结构特性，使其具有良好的阻垢和缓蚀性能，优于常用的有机膦酸，特别在高温下阻垢性能远优于常用的有机膦酸，能提高锌的溶解度，耐氯的氧化性能好，复配协同性好。

二、质量指标 符合HG/T 3662-2000

三、用途

PBTCA在高效阻垢缓蚀剂复配中应用最广，是性能最好的产品之一，也是锌盐的优良稳定剂。广泛应用于循环冷却水系统和油田注水系统的缓蚀阻垢，特别适合与锌盐、共聚物复配使用，可用于高温、高硬、高碱及需要高浓缩倍数下运行的场合，PBTCA在洗涤行业中可作螯合剂及金属清洗剂。

四、应用范围与使用方法

PBTCA一般与锌盐、共聚物、有机磷、唑类等其它水处理剂复配使用。如单独使用投加剂量为5~15mg/L。

五、包装与贮存

PBTCA用塑料桶包装，每桶25Kg或250Kg。贮存于室内阴凉处。贮存期十二个月。

六、安全防护

PBTCA为酸性，应避免与眼睛、皮肤接触，一旦溅到身上，应立即用大量水冲洗。

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:

Usage:

PTBCA is a high efficient agent as scale and corrosion inhibitor. It 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. It 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.

PTBCA 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:

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

Safety Protection:

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