✦ Synopsis

The sulfunc acid catalyzed absorption and reaction of lsobutene was studied 111 a bubble column (10 2 cm drameter, 256 cm he&t) covermg a wide range of hqmd phase compositions At acid concentrations of 40-48% wt and tert-butanol concentrations of 3 2-4 3 molesn the absorption rate has a maxunum value From measurements m the slow reaction or Muslonal re@me of mass transfer It was possible to obtam a value of hqmd side mass transfer coefficleat kL As mterfacm! areas and solubtibes of lsobutene were determmed by Independent means the rate constants of the hydration could be evaluated from this and other studies m bubble column reactors The reaction rate constant follows a simple correlation which considers the effect of the acld and the generated butanol Thus, all relevant data of the absorption-reaction system are avadable The slgmficance of these data was checked by a dynanuc study m a smaller bubble colt&

The absorption and reaction of isobutene in sulfuric acid yielding tert-butanol was studied in a bubble column of 4.6 cm diameter and 105 cm length. The inlet concentration of acid was varied from 28.5 to 56.9 wt%. A simple absorption model was used which shows that the absorption rate depends on th

## Abstract The activation energy parameters for the reaction of PdX (X=Cl^−^, Br^−^) in aqueous halide acid solution with thiourea (tu) and selenourea (seu) have been determined. High rates of reaction parallel low enthalpies and appreciable negative entropy of activation. The rate law in each cas
