Title (EN) METHOD OF PREPARING PENTACHLORODISILANE AND PURIFIED REACTION PRODUCT COMPRISING SAME
(FR) PROCÉDÉ DE PRÉPARATION DE PENTACHLORODISILANE ET PRODUIT RÉACTIONNEL PURIFIÉ COMPRENANT CELUI-CI
Abstract:
(EN) A method of preparing pentachlorodisilane is disclosed. The method comprises partially reducing hexachlorodisilane with a metal hydride compound to give a reaction product comprising pentachlorodisilane. The method further comprises purifying the reaction product to give a purified reaction product comprising the pentachlorodisilane. The purified reaction product comprising pentachlorodisilane formed in accordance with the method is also disclosed.
(FR) L'invention concerne un procédé de préparation de pentachlorodisilane. Le procédé comprend la réduction partielle d'hexachlorodisilane avec un composé hydrure métallique pour donner un produit réactionnel comprenant du pentachlorodisilane. Le procédé comprend en outre la purification du produit réactionnel pour obtenir un produit réactionnel purifié comprenant le pentachlorodisilane. L'invention concerne également le produit réactionnel purifié comprenant du pentachlorodisilane formé conformément au procédé.
