Definitions
- Citric acid and its salts are extremely widespread in living nature. In addition to its occurrence in numerous plants and fruits suitable for human consumption, citric acid is a central intermediate in the breakdown of foodstuffs to carbon dioxide and water. With a ubiquitous metabolic product, the biodegradability is naturally good. In the OECD test, 98% of citric acid and trisodium citrate are broken down within 24 hours. Wastewater treatment is not adversely affected. Lemon Acid generally has a low, mainly pH-related, acute aquatic toxicity. Citrates are not eutrophic. Solid citric acid and citric acid solutions with a content of less than 50% are classified in water hazard class 0. The neutral TNC has an even lower hazard potential than water. In general, it can be said that, not least, environmental considerations have brought citrates into focus as a replacement for TPP.
- the usual dispersants such as polyacrylates are the salts of relatively weak acids and strong bases, in most cases sodium hydroxide solution. So that these products can develop their maximum dispersing effect, all acidic groups must be in the anionic form, ie completely neutralized. If you now z. B. titrated polyacrylic acid with sodium hydroxide solution, you reach the equivalence point, depending on the concentration of the solution, only between pH 8 and 9, in this area is also the maximum of the dispersion. It is also known that the viscosity of the clay slurry (alumina) increases again with a further increase in pH / Vert.
- the polyelectrolyte titration determines the consumption of cationic poly-DAD-MAC (polydiallyldimethylammonium chloride) which is required for the charge neutralization of anionic dispersants.
- DAD-MAC polydiallyldimethylammonium chloride
- Example 2 Dispersion experiments of bulk kaolin A with different dispersant systems and different pH values
- Example 3 Dispersion experiments of bulk kaolin B with NaOH and various dispersants in the weakly acidic pH range
