J. Jayasree et Cs. Narayanan, CATALYTIC TRANSFORMATION OF (-LIMONENE OXIDE OVER BINARY OXIDE CATALYSTS OF ALUMINA RARE-EARTHS()), Indian journal of chemistry. Sect. B: organic chemistry, including medical chemistry, 36(1), 1997, pp. 9-13
The transformation reactions of (+)-limonene oxide over binary oxides
like Al2O3-Y2O3, Al2O3-Sm2O3, Al2O3-Eu2O3, Al2O3-Pr6O11 and Al2O3-Nd2O
3 at 110 degrees C and 140 degrees C are discussed, The activity of si
ngle oxides like Al2O3, Eu2O3, Nd2O3 and Y2O3 used for the transformat
ion reaction is studied at 110 degrees C. Among the binary.oxides, Al2
O3-Eu2O3 show maximum activity for epoxide transformation. Methyl (3-i
sopropenyl cyclopentyl) ketone (4) and carvone (5) are the major produ
cts formed over binary oxides at higher reaction temperture.
