Abstract

Allyl, benzyl, n-butyl, n-octyl and cetyl acetates are obtained in very good yields (⩾ 92%) at room temperature by reacting finely-ground CH3COOK and the corresponding alkyl bromide without any solvent and in the presence of catalytic amounts of tetra-alkyl ammonium salts (NBu4Br or Aliquat 336). Effects of addition of mineral oxides have been studied, catalytic effects due to small quantities of TiO2, ZrO2, talc, glass dust and Celite, inhibition effects ...
