Jf. Izquierdo et al., KINETIC-STUDY OF ISOBUTENE DIMERIZATION CATALYZED BY A MACROPOROUS SULFONIC-ACID RESIN, Applied catalysis. A, General, 106(1), 1993, pp. 155-165
The kinetics of the liquid-phase dimerization of isobutene in the pres
ence of a macroporous acidic resin (Lewatit K-2631, Bayer) has been st
udied. Rate data were obtained in a batchwise stirred tank reactor ope
rated at 1.6 MPa and 40-60 degrees C. The best rate model is a two-pha
se semiempirical one which implies the coexistence of a Langmuir-Hinsh
elwood-Hougen-Watson mechanism and a modified Eley-Rideal one.
