| 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 | Purification Methods | Recrystallise it from AcOH, EtOAc, *C6H6 or *C6H6/EtOH. It forms two stable isomorphs and both forms, as well as the mixture, melt at 200-201o. There is a metastable form which melts at 187-189o. [Burkhard et al. J Am Chem Soc 67 2174 1945, Hyde et al.
