Abstract: The γ-tert-butyl peroxide propyltrimethoxysilane was synthesized with tert-butyl hydroperoxide and 3-chloropropyltrimethoxysilane,catalyzed by ferric chloride in toluene for the first time. The product was characterized by IR、¹H NMR and mass spectra,and its structure was determined. Synthetic conditions such as the catalyst species,the reactants ratio,the reaction temperature and time were discussed. The optimal conditions were determined as follows:n(tert-butyl hydroperoxide):n(3-chloropropyltrimethoxysilane)=1.2:1,m(catalyst):m(3-chloropropyltrimethoxysilane) =0.015:1,reaction temperature of 40℃ and reaction time of 8h. The yield of the product could reach 42% under the optimal reaction condition.

Key words: tert-butyl hudroperoxide, γ-tert-butyl peroxide propyltrimethoxysilane, synthesis, catalyst, optimization
