METHOD OF SYNTHESIS OF HIGH-PURE ORGANOSILICON DISULFANES Russian patent published in 2003 - IPC

Abstract RU 2199544 C2

FIELD: chemistry of organosilicon compounds, chemical technology. SUBSTANCE: invention describes method of synthesis of high-pure organosilicon disulfanes by two-stage reaction that involves interaction of elemental sulfur and alkaline metal anhydrous sulfide with halogenalkylalkoxysilane followed by addition of additional amount of alkaline metal sulfide. Invention provides synthesis of high-pure substance with high yield percent. EFFECT: improved method of synthesis, increased yield. 4 ex
