PBTC CAS 37971-36-1
Sinochem is a major PBTC & 2-Phosphonobutane-1,2,4-tricarboxylic acid supplier. Meanwhile, our firm staffs a group of experts devoted to your development of China PBTC & 2-Phosphonobutane-1,2,4-tricarboxylic acid.
2-Phosphonobutane-1,2,4-tricarboxylic acid is a scale and corrosion inhibition agent.
- Scale inhibition performance: PBTC has a very effective inhibitory effect on common scales such as calcium carbonate and calcium phosphate, and can significantly reduce the formation of scale.
- Corrosion inhibition performance: PBTC can increase the solubility of zinc ions and enhance the stability of zinc salts, so that it can still maintain a good corrosion inhibition effect under high pH conditions.
- Dispersion performance: PBTC has good dispersion ability for circulating water with high turbidity and high iron content, which helps to keep the water clear.
- Thermal stability: Even under high temperature conditions, PBTC can maintain stable performance and is suitable for high temperature water treatment systems.
- Chlorine resistance: PBTC has good tolerance to chlorine gas and chlorine products, and is suitable for chlorine-containing water treatment environments.

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. 2-Phosphonobutane -1,2,4-Tricarboxylic Acid can improve zinc salt solubility, has good chlorine oxidation tolerance and good composite synergy.
Usage:
1. 2-Phosphonobutane -1,2,4-Tricarboxylic Acid 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.
2. 2-Phosphonobutane -1,2,4-Tricarboxylic Acid 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 : Normally In 250kg net Plastic Drum, IBC drum can also be used as required.
Storage: Plastic drum, net weight 35kg; Lined with polyethylene and stored for more than 2 years. If the temperature is too low to cure, after thawing or continue to use without adverse effects. Because this product has a certain corrosion effect on the material, the receptors, pumps and pipelines should be made of stainless steel, glass and plastic (such as polyethylene).
Safety Protection: Acidity, Avoid contact with eye and skin, once contacted, flush with water.
About Us: With over many years as a certified PBTC & 2-Phosphonobutane-1,2,4-tricarboxylic acid manufacturer, we combine innovation with stringent production standards to deliver high-performance product.
