N-Alkylation of aniline over silica and montmorillonite K10: the influence of oxide impregnation
10 wt.% vanadia, zirconia and chromia impregnated silica and montmorillonite K10 catalysts have been prepared. They were characterised by surface area measurements, XRD and ESR. Acidity was determined by stepwise ammonia desorption at three temperature ranges (A= 353–423 K, B=423–573 K, C=573–723 K). Aniline alkylation was carried out at 673 K, 12 cm3 h−1 g−1 (feed rate) and atmospheric pressure. The catalytic conversion is explained on the basis of acidity differences.
