Technology Process of HEXACHLORODISILANE

There total 27 articles about HEXACHLORODISILANE which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use. At the same time, we analyze and calculate the most feasible synthesis route with the highest yield for your reference as below:

synthetic route:

Reference yield: 80.0%

silicon (7440-21-3) → tetrachlorosilane (10026-04-7,53609-55-5) + hexachlorodisilane (13465-77-5) + perchlorotrisilane (13596-23-1)

Guidance literature:

In neat (no solvent); chlorination of crude Si at 300-310 °C; best yield of SiCl4;;

Reference yield: 55.0%

hexaphenyldisilane (1450-23-3) + acetyl chloride (75-36-5) → hexachlorodisilane (13465-77-5)

Guidance literature:

With aluminium trichloride; In hexane; Ph3SiSiPh3, AlCl3 and CH3COCl in hexane were stirred overnight; hexane added; upper phase septd.; hexane removed (vac.); redistd.;
