PREPARATION AND CHARACTERIZATION OF TERMINAL HYDROGEN SILICONE OIL
Journal Title: Topics in Chemical & Material Engineering (TCME) - Year 2018, Vol 1, Issue 1
Abstract
The terminal hydrogen silicone oils are often used as raw material for the synthesis of amino, epoxy and polyether terminated silicone oil that is used widely to formulate oil agents for carbon fiber precursor. The terminal Hydrogen silicone oil can be synthesized by using octamethylcyclotetrasiloxane (D4) and hydrogen dual head (dihydro-tetramethyl disiloxane) (HMM) as raw materials and 98% sulfuric acid as catalyst in this article. Our group reported two synthetic scheme of terminal hydrogen silicone oil and studied effect of reaction activity of D4 and HMM on its molecular weight. The first synthetic scheme is to put all starting raw materials into the reactor together and to trigger the reaction by catalyst. The second synthetic scheme is to let HMM of low reaction activity to start reaction and then to initiate the ring opening polymerization of D4
