Hexadecyltrimethylammonium hydroxide Chemical Properties,Usage,Production

Chemical Properties

clear colorless to pale yellow solution

Uses

Hexadecyltrimethylammonium hydroxide solution is a surfactant used in:

• Synthesis of microporous and mesoporous aluminosilicate molecular sieves such as MCM-41 and MCM-48.
• Hydrothermal preparation of manganese dioxide (MnO₂) nanoflower.
• Synthesis of cetyltrimethylammonium hydroperoxide, a reagent used for promoting phosphate ester hydrolysis.

Uses

Hexadecyltrimethylammonium hydroxide solution is a commonly used phase transfer agent and surfactant solution employed in the synthesis of a variety of mesoporous materials, micelle complexes and transition-metal oxides.
