96% Purity Low Magnesium Calcium Hydroxide for The Production of Sulfonate

Overview

Purity ≥96%

The main component, calcium hydroxide (Ca(OH)₂), accounts for ≥96%, far higher than that of ordinary industrial-grade calcium hydroxide (typically 85%~92%), with extremely low impurity levels.

This high purity makes it advantageous in impurity-sensitive applications such as pharmaceuticals, food, and high-end chemistry.

Extremely Low Magnesium Content

The magnesium content (calculated as MgO) is usually ≤0.5%, significantly lower than that of ordinary calcium hydroxide (1%~3%).

The low magnesium content avoids interference from magnesium ions in product performance (e.g., affecting chemical reaction selectivity or reducing material stability).

Due to its high purity and low impurity content, as a neutralizer, precipitant, or catalyst, it enables faster reaction speeds and fewer byproducts, improving production efficiency and reducing post-processing costs.

Application

96% low-magnesium calcium hydroxide can be used in the production of sulfonates for lubricant additives, and its high purity and low magnesium content offer significant advantages in this field.Sulfonates  commonly used as detergents and rust inhibitors in lubricants.

High Purity Ensures Reaction Efficiency and Product Quality

Ca(OH)₂ content ≥96%: Provides an adequate supply of OH⁻ ions to ensure complete neutralization of sulfonic acid, preventing residual free acid and reducing corrosion to lubricants.

Low impurities:

Metal impurities (e.g., Fe, Al) in ordinary calcium hydroxide may form byproducts with sulfonic acid, affecting the transparency and thermal stability of sulfonates. 

The low magnesium content (MgO ≤0.5%) is particularly critical: Magnesium ions may form slightly soluble magnesium salts with sulfonic acid, causing turbidity or precipitation in sulfonate systems and affecting the uniformity of lubricant additives.
