Technology Process of Cyclotrisiloxane, hexachloro-

There total 4 articles about Cyclotrisiloxane, hexachloro- 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: 20.5%

tetrachlorosilane (10026-04-7,53609-55-5) + (benzyloxy)trichlorosilane (18141-27-0) → hexachlorocyclosiloxane (103084-63-5) + hexachlorodisiloxane (14986-21-1) + benzyl chloride (100-44-7) + (benzyloxy)pentachlorodisiloxane

Guidance literature:

In neat (no solvent, gas phase); mixt. of SiCl4 and PhCH2OSiCl3 are passed through empty quartz tube heated to 620°C (20-30 sec stayed in reaction zone, gas phase reaction), further product: Cl3SiOSiCl2OSiCl3 (10.5%);

Reference yield: 1.5%

tetrachlorosilane (10026-04-7,53609-55-5) + oxygen (80937-33-3) → octachlorotrisiloxane (31323-44-1) + cyclooctachlorotetrasiloxane (67777-49-5) + decachloro tetrasiloxane (56240-64-3) + hexachlorocyclosiloxane (103084-63-5) + hexachlorodisiloxane (14986-21-1)

Guidance literature:

In neat (no solvent); byproducts: Cl2; reaction of gaseous SiCl4 and O2 at 955°C, products are condensed at 55°C; destillation, sublimation;

Reference yield:

tetrachlorosilane (10026-04-7,53609-55-5) + dimethyl sulfoxide (67-68-5,8070-53-9) → Si5O5Cl10 (110920-53-1) + cyclooctachlorotetrasiloxane (67777-49-5) + hexachlorocyclosiloxane (103084-63-5) + (Cl2SiO)6 (130969-98-1) + hexachlorodisiloxane (14986-21-1)

Guidance literature:

byproducts: HCl, ClCH2SCH3; DMSO slow addn. to Si-compd. on cooling (0°C), slow heating, sulfide distillation off, hexachlorodisilane distillation off; ppt. filtration off, washing (CCl4), distillation off in vacuum, productidentification by gas chromatography-mass spectrometry; further product s;
