Abstract
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.
