Rm. Deshpande et al., KINETICS OF HYDROFORMYLATION OF ETHYLENE IN A HOMOGENEOUS MEDIUM - COMPARISON IN ORGANIC AND AQUEOUS SYSTEMS, Industrial & engineering chemistry research, 37(6), 1998, pp. 2391-2396
The kinetics of hydroformylation of ethylene was studied using HRh(CO)
(PPh3)(3) and [Rh(COD)Cl](2)/TPPTS catalyst in toluene and water media
, respectively. The rates were found to have a first-order dependence
on the catalyst concentration. Similar trends were observed with respe
ct to partial pressures of ethylene and carbon monoxide, in both solve
nts. The difference in the location of the maxima with respect to pres
sure is due to the poor solubility of the reactants in water as compar
ed to toluene. The major difference observed was a 1.5 order with hydr
ogen in toluene compared with a first order in water. Rate models were
proposed to represent the data observed.
