2) The synthesis of Q8 products
|
|
Q-1 is synthesized by reaction of a silicate source (Rice-Hull-Ash etc.) and tetraalkylammonium hydroxide (Fig. 4).

|
Q-2 is synthesized by reaction of Q-1 and chlorodimethylsilane. Q-6 is synthesized by the reaction of Q-1 and chlorodimethylvinylsilane (Fig. 5).

Various Q8 products bearing different functional group are made by using
hydrosilylation or other reactions from Q-2 (Fig. 6).
