Methanol, ethanol, and i-propanol were converted under methanol-to-gasoline (MTH)-like conditions (400 degrees C, 1-20 bar) over zeolite H-ZSM-5. For methanol and ethanol, the catalyst lifetimes and conversion capacities are comparable, but when i-propanol is used as the reactant, the catalyst lifetime is increased dramatically. In fact, the total conversion capacity (calculated as the total amount

The properties of the heterophase system perfluorodecalin-acetonitrile differ significantly from those of other combinations of the organic solvents limitedly soluble in each other. While for the most of such combinations the distribution coefficients (K (d)) of homologues increase in going from the simplest to next members of the series, in the case of perfluorodecalin-acetonitrile they remain almost constant. This provides a possibility to use the values of K (d) directly for the group identification of analytes, and first of all allows distinguishing isomeric alkenes and cycloalkanes, as well as the isomers of the hydrocarbons with greater formal unsaturation.
