Tetrasodium Iminodisuccinate (IDS): Alkali Resistance & Applications

In today’s pursuit of sustainable development, green and environmentally friendly water treatment agents have become a key focus in the chemical industry. Among them, Tetrasodium Iminodisuccinate (IDS) stands out as a star product in industrial water treatment due to its exceptional alkali resistance. This article delves into the advantages of IDS in alkaline environments and highlights Yuanlian Chemical's technological innovations and practical applications in this field, providing professional insights for the industry

1. Chemical Properties and Alkali Resistance of Tetrasodium Iminodisuccinate

Tetrasodium Iminodisuccinate is a green, biodegradable chelating agent. Its molecular structure, featuring multiple carboxyl groups and nitrogen atoms, grants it outstanding metal ion chelation capabilities. Compared to traditional organophosphonates, IDS performs particularly well in high-alkaline environments:

1. Wide pH Adaptability: IDS maintains a stable chemical structure across a pH range of 2–14, with its chelation performance largely unaffected even in highly alkaline conditions (pH > 10).

2. High-Temperature Stability: IDS remains effective as a chelating agent even at temperatures above 80°C in alkaline environments, making it suitable for various demanding industrial applications.

3. High Calcium Tolerance: In hard, alkaline water, IDS retains excellent scale inhibition properties, preventing the formation of scales such as calcium carbonate and calcium sulfate.
