Abstract
The adsorption of some hydroxy-acids (i.e. citric, tartaric and salicy lic) on a gamma-alumina support has been investigated by transmission FT-IR. The results imply that the observed changes in the IR spectrosc opic properties of the supported hydroxy-acids are mainly due to inter action of the acids with alumina hydroxyl groups. The IR spectra in th e C=O stretching region of the hydroxy-acids supported on alumina are quite different from those of the unsupported compounds.
