FIELD: chemistry.
SUBSTANCE: disclosed is a method of producing trimethylfluorosilane from hexamethyldisiloxane and hydrofluorosilicic acid, wherein the hexamethyldisiloxane reacts with 10-30% hydrofluorosilicic acid solution while heating in the presence of an acid, such as sulphuric acid or para-toluene sulphonic acid.
EFFECT: method is technologically effective and environmentally friendly since it does not require special equipment and enables to recycle wastes from large-tonnage production of phosphorous fertiliser.
