Abstract

Electrocatalytic reduction and polarization behaviour of allyl chloride and chloral hydrate was studied at a platinized platinum electrode in acidic medium. In both cases formation of gaseous products has been observed. Allyl chloride transforms into propene and propane. The ratio of unsaturated and saturated hydrocarbons can be influenced by poisoning of the electrode with chemisorbed methanol. Polarization behaviour shows that the rate-determining step of the reaction is a charge-transfer process connected with the splitting of the C-Cl bond in allyl chloride. Reduction of chloral hydrate results in ethane (90%) and methane (10%). No simple polarization behaviour can be observed. A probable reaction sequence leading to the gaseous products is proposed on the basis of data obtained from electrocatalytic and catalytic studies.
