Molecular formula : (C2H5) (C6H5) Si (OH ) 2 CAS :
nature : 70 ° C melting point. The acid, alkali or amines catalytic heating elements connected with the silicon hydroxy condensation dehydration, straight-chain formation of poly ethyl glycol and PMPS ethyl phenyl ring polysiloxane. The role of concentrated sulfuric acid, Si-C6H5 bond rupture. Si-OH with Si-NR2 and Si-Cl bond occurred miscellaneous functional groups condensation reaction, and were released HNR2 HCl and form as stability of Si-O-Si bond. May dichloro phenyl ethyl Silane hydrolysis admission to the system. Silicone used synthetic intermediates and polymers, silicone rubber for the structural control agent.
