What is the PBTC chemical?
PBTC (2-phosphonobutane-1,2,4-tricarboxylic acid) is an efficient water treatment agent with excellent scale and corrosion inhibition properties. It is in chaical formula C7H11O9P, molecular weight is 270.13, it is a colorless or light yellow transparent liquid with the following characteristics and application scenarios:
1. Chaical stability: PBTC has good thermal stability and stability against hydrolysis, hydrolysis has not been found in water up to 120°C, acid, alkali and oxidizer resistant .
2. Solubility: it can be miscible with water in any proportion, the pH value of 1% aqueous solution is 1, and it can be used as a chelating agent and metal cleaning agent in detergent industry.
3. Safety: The toxicity of PBTC is low, the oral LD50 of 50% aqueous solution of PBTC for rats is more than 6500mg/kg, but it has a moderate irritating effect on the eyes of rabbits, so it needs appropriate protective measures when used.
4. Application field: PBTC is widely used in circulating cooling water systa and oilfield water injection systa corrosion and scale inhibition, especially suitable for compounding with other water treatment agents such as zinc salts, copolymers, etc., and is suitable for high taperature, high hardness, and high alkalinity water quality conditions.
5. Synergistic effect: PBTC has excellent complexing ability with Ca2+, Zn2+, Mg2+ and other ions, and has good synergistic corrosion inhibition with zinc salt and polyphosphate.
6. Environmental impact: PBTC's tolerance to chlorine or chlorine products and trivalent iron ions in water is better than that of other phosphonates, which makes it useful in a variety of water conditions.
7. Production method: The synthesis of PBTC usually involves an addition reaction between phosphite and maleate in the presence of a catalyst, followed by an addition reaction with acrylate, and finally hydrolysis in an acidic medium to obtain the final product .
8. Price Information: The price of PBTC varies according to market conditions, for example, on April 30, 2024, the price of reagent grade PBTC was $77 for a 500G package and $190 for a 25G package .
