Al-MCM-41 (Si/Al = 20) molecular sieve was synthesized hydrothermally and phosphotungstic acid (PW) of 10, 20 and 40 wt% was supported on it. Their catalytic performance was examined in the vapour phase alkylation of phenol with tert-butyl alcohol (TBA) in the temperature range 190-275 Β°C. The major
Esppsure of aqueous glassy solutions of f-butyl alcohol to 6oCo vlays at 77Β°K gave ESR spectra characteristic of h!e& and H2CC(hfe)20H radicals. The results for the former were unusual in fh?t, for very dilute aqueous solutions and for solutions of 0.4 mole fraction through to the pure alcohol, all
