Octaphenylcyclotetrasiloxane Chemical Properties,Uses,Production
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.
