FOLETTO, E.L.; VALENTINI, A.; PROBST, L.F.D. y PORTO, L.M.. Gas-phase β-pinene isomerization over acid-activated bentonite. Lat. Am. appl. res. [online]. 2002, vol.32, n.2, pp. 141-144. ISSN 0327-0793.
The kinetics of the gas-phase isomerization of β-pinene over an acid-activated bentonite clay has been investigated in a fixed-bed continuous flow reactor, at atmospheric pressure between 58 and 90 oC. The major isomers produced were camphene, α-pinene and limonene. The reaction rates of β-pinene conversion and the apparent activation energy were determined. The kinetics of β-pinene isomerization was described by zero-order kinetics with an activation energy of 30-35 kJ/mol for the major products formed.
