Analysis of Components of Surface Modifier for Inorganic additives

The surface modifier of in organic additives was dissolved with CHCl3,and the filtrate obtained was identified by GC-MS.The relative contents (in %) of the components were determined using the method of normalization.Seventeen chemical components were identified on the base of the TIC chromatogram.Contents of the 3 main components were as follows: cetylic acid (48.50%),olefin (29.88%) and octadecanoic acid (11.97%).The filter residue was analyzed by IR spectroscopy,and the main component found was oxide of polythene wax.
