| Octaphenylcyclotetrasiloxane Usage And Synthesis |
| Chemical Properties | Octaphenylcyclotetrasiloxane (OPCTS) is a white solid. It can be used for synthesizing pharmaceutical intermediates and organic silicone intermediates, especially for high temperature resistant phenyl silicone oil and other polymers. |
| Preparation | Octaphenylcyclotetrasiloxane is typically produced industrially by one of two processes: 1) the hydrolysis of diphenyldichlorosilane or 2) the hydrolysis of diphenyldialkoxysilanes.
Process the production of octaphenylcyclotetrasiloxane |
| Flammability and Explosibility | Not classified |
