Zusammenfassung:	FIELD: organic chemistry, chemical technology. SUBSTANCE: method involves sodium melting and its interaction with dimethyldichlorosilane at molar ratio 1:(1.9-3.6), respectively, at boiling point of dimethyldichlorosilane. Yield is 96.4%. Synthesized compound is used for continuous and highly strength siliconcarbide fiber making. EFFECT: increased yield of product. 1 tbl, 5 ex Использование: непрерывные и высокопрочные кремнийкарбидные волокна. Сущность: расплавление натрия и взаимодействие его с диметилдихлорсиланом при молярном соотношении 1:(1,9 - 3,6) соответственно при температуре кипения диметилдихлорсилана. Выход до 96,4%. 1 табл.
