PBTCA (terephthalic acid-1,2,4-tricarboxylic acid) is a commonly used chelating agent used in water treatment, industrial cooling water systems and other related applications. It consists of several components, the main components may include the following:
1. Terephthalic acid acid (PBA) : terephthalic acid is one of the main components of PBTCA. It is an organic acid with good chelating ability to metal ions.
2.1,2,4-tricarboxylic acid (TCA) : another major component of PBTCA, 1,2,4-tricarboxylic acid is one of the sources of its nomenclature. It is a kind of organic acid containing three carboxyl groups, and can form a stable complex with metal ions.
3. Alkalinity: to regulate the pH of PBTCA and increase its solubility, small amounts of alkalinity, such as sodium hydroxide (NaOH) or potassium hydroxide (Koh) , may be added.
4. Other additives: depending on the specific needs, may be added some auxiliary ingredients, such as buffer, stabilizer, co-solvent, etc. , to enhance the performance and stability of PBTCA.
It is important to note that different manufacturers and products may use different formulations and composition combinations, there may be subtle differences. When using PBTCA or any other chemical, read the product instructions carefully and follow the correct method of use and safe operating procedures to ensure safe use and desired results.
