Application

Hexadecyltrimethylammonium chloride can be used as a precursor to synthesize MCM-41 (Mobil Oil, Composition of Matter No. 41), a uniform mesoporous material at room temperature by a two-step sol-gel process.
Hexadecyltrimethylammonium chloride (CTAC) is a cationic surfactant that can be used:
  • For the preparation of Polymethylsilsesquioxane aerogels (PMSQ) from methyltrimethoxysilane (MTMS) by hydrolysis and polycondensation reaction.
  • To determine iodine and iodide in commercial gargle products by luminol chemiluminescence.
  • As a template along with cetyltrimethylammonium bromide (CTAB) to prepare rod-like mesoporous silica from sodium silicate as a precursor.
  • As a catalyst in the synthesis of 2-amino-2-chromenes from aldehyde, malononitrile, and phenol by one-pot three-component reaction.
