The gas phase chlorination of propane over different catalysts, including those containing ruthe nium oxychlorides as the active component, has been investigated. The propylene and chlorine containing product formation selectivities in propane chlorination at 150-450°C in a fixed bed flow reactor have been determined.
The interaction of aUoocimene with ct-methacrolein on 13-zeolite with various substituent cations (Fe, Ni, Zn, Cu and La) as well as on ZSM-5, erionite and mordenite has been studied at room temperature in dichloromethane. Substituent cations in 13-zeolite as well as the silica/alumina ratio and alkali metal content in the zeolite structure were found to affect the formation of ocinal diastereomers. Therefore, we assume that a complex of active sites participates in the diene condensation: Alkali metals present in the zeolite suppress the (3+2)-cycloaddition reaction.
Condensation of Stereoisomeric Alloocimenes with α-Methylacrolein on Zeolites.-The title reaction leads to the cyclic products (III) and (IV) diastereoselectively. The product ratio is found to depend on the zeolite used and the ratio of E/Z isomers of the starting material ( yields not given). -(TATAROVA, L. E.; SALAKHUTDINOV, N. F.; KORCHAGINA, D.
