Abstract
Process for the preparation of amides via the catalytic rearrangement of oximes which comprises putting an oxime in vapor phase in contact with a catalyst selected from a mesoporous silica-alumina having a molar ratio SiO/Al.sub.2 O.sub.2 of between 20 and 1000, an average pore diameter of between 20 and 100 .ANG. and an X-ray diffraction pattern (XRD) from powders which, after calcination, has the deepest reflection at d-spacing of more than 18 .ANG. (2.theta.<4.9.degree., CuK.alpha. radiation).
