- W2079733374 abstract "The rates of the ring-opening reaction of isobutylene oxide have been measured in methyl, ethyl, w-propyl and isopropyl alcohols in the range from 10 to 40°C under conditions where the molar ratio of an alcohol to the epoxide was kept at 10 and the range of the concentration of boron trifluoride etherate was ca. 1.0×10−3 to ca. 4.0×10−3 mol/l. The rate equation is expressed as follows: −d[epoxide]⁄dt=k2[C0][epoxide], where [C0] is the initial concentration of the catalyst and [epoxide] is the instantaneous concentration of the epoxide at time t. The rate constants (k2) decreased in the order, CH3OH>C2H5OH>n-C3H7OH>i-C3H7OH. The entropies of activation decreased in the same order, while the energies of activation were not appreciably changed. A plot of logk2 against 1/D (D, the dielectric constant of the mixture of each alcohol and the epoxide) was found to be linear, its slope being −61.2. The results support the fact that the reaction is bimolecular." @default.
