Resumo: A atividade catalítica do fosfato de nióbio foi avaliada na reação de alquilação em fase líquida do anisol com 1-dodeceno, 1-octeno, 2-octanol e 1-octen-3-ol e na reação do fenol com 1-octen-3-ol. Melhores resultados foram alcançados na alquilação do anisol e do fenol com 1-octen-3-ol que produziu principalmente produtos monoalquilados. Na reação com o fenol e 1-octen-3-ol os principais produtos formados foram os octenil-fenóis (C-alquilação) e o fenil-octenil éter (O-alquilação). A reação favorece a formação de C-alquilados em relação aos O-alquilados.

Best results were achieved in the alkylation of anisole and phenol with 1-octen-3-ol that produced mainly monoalkylate products. In the reaction with phenol the major products formed were octenylphenols (C-alkylation) and phenyl-octenyl ether (O-alkylates). The reaction favors the formation of C-alkylates over O-alkylates.Universidade Federal do Rio de Janeiro. Instituto de Química. Rio de Janeiro, RJ, Brasil.Fundação Oswaldo Cruz.
