Catalytic Reactions of 1-Butanol over AlPO Catalysts Induced by BO
A series of AlPO 4 –B 2 O 3 samples containing 5–50 wt% B 2 O 3 were prepared. Their textural properties were determined from studies of the adsorption of nitrogen at −196°C. The structural characteristics were investigated using DTA, TG, XRD and FT-IR methods. Surface acidity was determined from th...
