(Trimethylsilyloxy) potassium - Reference Information
| EPA chemical information | Information provided by: ofmpub.epa.gov (external link) |
| Uses | Potassium trimethylsilanol is a common catalyst for polymerization catalysis and ring-opening catalysis for the preparation of polysiloxane. The catalyst is used for polymerization catalysis and The ring-opening catalytic reaction has no methanol, no polychlorinated biphenyls and polychlorinated phenols in the residue, so it has been widely used in polymerization catalysis and ring-opening catalysis. |
| preparation | 109kg of hexamethyldichlorosilane is put into a stirred kettle, nitrogen is introduced at a flow rate of 1L/min for 0.5h while stirring, 56kg of potassium hydroxide is added after refluxing at 100 ℃ for 10h, then the material is put into a centrifugal spray drying oven, and the white crystal product is obtained by centrifugal spray drying at 3000rpm and 100 ℃ for 5h, the purity is 99.99%. |
