ABSTRACT:
Highly pure disilicon hexafluoride is synthesized by a process in which a suspension of a fluorination agent is made by dispersing this fluorination agent in an oxybenzene compound as a solvent and disilicon hexachloride is dripped in the suspension to be caused to react with the fluorination agent in nitrogen gas flows under atmospheric pressure, the oxybenzene being expressed by a following formula: ##STR1## (where each of R.sub.1 and R.sub.2 is an alkyl group alternatively having one or more substituents; carbon numbers summed up by R.sub.1 and R.sub.2 are equal to at least 2; and m.gtoreq.1 and n.gtoreq.0).
