ABSTRACT:
Cyclohexyl acetate is produced by reacting acetic acid with cyclohexene in the presence of a heteropolyacid mainly composed of oxides of tungsten as a catalyst. The heteropolyacid may have water of crystallization adjusted to the amount of average 3.0 molecules or less per one molecule of the heteropolyacid. Cyclohexyl acetate can be produced in high selectivity and high conversion. The catalyst is effective even at a low temperature and stable even at a high temperature.
