The vapour phase tert-butylation of naphthalene was carried out over modified Y, MCM-41 and SAPO-5 catalysts. CeY was found to be better catalyst among the catalysts screened for this reaction at 200 °C reaction temperature and 0.5 h −1 weight hourly space velocity (WHSV). Various reaction parameter...
