Abstract : The hydrolysis and condensation reaction kinetics of methoxydimethyloctylsilane (MDOS) and copper nitrate hydrate were investigated using analytical measurements and Karl Fischer titration. The reaction product was determined to be a dimer of MDOS, tetramethyldioctyldisiloxane (TDDS). The structure of TDDS was confirmed by FTIR, (29)Si NMR and (1)H NMR. The initial rates of the hydrolysis and condensation were determined for the half-life of the reaction. The phase separation of TDDS and the reaction mixture was found to be quantitative. The correct stoichiometry reacted all the water and MDOS in solution and resulted in an anhydrous copper nitrate solution in methanol.
