실험 절차
Trichlorosilane and allyl chloride were subjected to hydrosilylation reaction in a solvent in the presence of a platinum catalyst, followed by esterification reaction with methanol and urea and further by distillation to obtain γ-chloropropyltrimethoxysilane. The thus obtained γ-chloropropyltrimethoxysilane and potassium acrylate were subjected to desalting in a solvent, followed by removal of potassium chloride. Subsequently, low boiling components including the solvent were distilled off under reduced pressure to obtain crude γ-acryloxypropyltrimethoxysilane having a purity of approximately 90%.
