Technology Process of dodecachloro pentasiloxane

There total 2 articles about dodecachloro pentasiloxane 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:

oxygen (80937-33-3) + chlorine (7782-50-5) + silicon (7440-21-3) → octachlorotrisiloxane (31323-44-1) + cyclooctachlorotetrasiloxane (67777-49-5) + decachloro tetrasiloxane (56240-64-3) + dodecachloro pentasiloxane (42931-29-3) + hexachlorodisiloxane (14986-21-1)

Guidance literature:

In neat (no solvent); reaction of a mixture of Cl2 and O2 (2:1) with Si in a glass tube at red heat; further products;; condensation and fractionation;;

DOI:10.1021/ja01855a072

Reference yield:

tetrachlorosilane (10026-04-7,53609-55-5) + dimethyl sulfoxide (67-68-5,8070-53-9) → octachlorotrisiloxane (31323-44-1) + decachloro tetrasiloxane (56240-64-3) + hexachlorocyclosiloxane (103084-63-5) + dodecachloro pentasiloxane (42931-29-3) + (Cl2SiO)6 (130969-98-1)

Guidance literature:
