[‚se·trə′mōn·ē·əm ′brō‚mīd]
(organic chemistry)
CH3(CH2)15N(CH3)3Br Crystals with a melting point of 237-243°C; soluble in alcohol, water, and sparingly in acetone; used as a cationic detergent, antiseptic, and precipitant for nucleic acids and mucopolysaccharides.

The oil shale residue formed in the process of oil production was modified with hexadecyl trimethyl ammonium bromide applying the method of orthogonal experiments varying the amount of surfactant (the molar ratio of the cationic surfactant to the hydroxyl group number N of the silica surface), reaction temperature and pH value of the reaction system.
One can see in Table 4 that the rates of modification with both hexadecyl trimethyl ammonium bromide and tetraethylammonium bromide are about 84%.
Two kinds of modified silica obtained from oil shale residue by taking hexadecyl trimethyl ammonium bromide and tetraethylammonium bromide as modifier, respectively, were analyzed by infrared spectra.
