METHOD OF PRODUCING TRIMETHYLFLUOROSILANE Russian patent published in 2015 - IPC C07F7/12

Abstract RU 2565678 C1

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.
