On the basis of X-ray phase analysis data we identified the main structural elements of the solid phase of domestic aluminosilicates of different colours used for the purification of mustard oil by sorption. Also we defined these materials fractional and particle size distribution and realized 60-80% of their particles are 0.3-2.5 µm in size. The study reveals the important role of rock-forming fractions kaolinite and montmorillonite (up to 15%), high dispersion and moderately alkaline surface (pH of 1% aqueous dispersion 8.40-8.43) of aluminosilicate materials by LLC "PolyServis-M" (Moscow) in oil neutralization and bleaching. By the experiment results introduction of these domestic materials into mustard oil prevents its oxidation.
