I.R. spectra of gaseous methyl chloroformate adsorbed on solid aluminum chloride catalyst are recorded and discussed. The first adsorption involves carbonylic oxygenatoms (electron donors) and Lewis acid sites (electron acceptors) on the catalyst's surface. The alkylating properties of the adsorbed specie are discussed according to the spectroscopic behaviour of stretching $\nu_{c-OR}$ vibration.
