摘要：

One-pot synthesis of cresols from toluene and hydroxylamine catalyzed by ammonium molybdate was investigated under mild conditions. The hydroxylation reaction was strongly dependent on reaction medium, temperature, the amount of catalyst and hydroxylamine. Moreover, the reaction took place more efficiently in a closed system than in open air. High toluene conversion (72.9%) and cresol selectivity (79.4%) were obtained at 80 degrees C in water-acetic acid-sulfuric acid medium. (C) 2011 Elsevier B.V. All rights reserved.
