Esterification of salicylic acid with dimethyl carbonate over mesoporous aluminosilicate / Xiaowei Su in Industrial & engineering chemistry research, Vol. 48 N° 7 (Avril 2009) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 48 N° 7 (Avril 2009) . - pp. 3685–3691 Titre : Esterification of salicylic acid with dimethyl carbonate over mesoporous aluminosilicate Type de document : texte imprimé Auteurs : Xiaowei Su, Auteur ; Junping Li, Auteur ; Fukui Xiao, Auteur Année de publication : 2009 Article en page(s) : pp. 3685–3691 Note générale : Chemical engineering Langues : Anglais (eng) Mots-clés : Methyl  salicylate  Salicylic  acid  Dimethyl  carbonate  Mesoporous  aluminosilicate Résumé : The synthesis of methyl salicylate (MS) from salicylic acid (SA) and dimethyl carbonate (DMC) was performed over a series of mesoporous aluminosilicates. The results showed that mesoporous aluminosilicate was an effective esterification catalyst for the reaction. It was also found that both SA conversion and MS selectivity were closely linked with the intermediate strong acidity and Lewis acidity of catalysts. As a result, the synergistic mechanism was proposed for the esterification of SA with DMC over a mesoporous aluminosilicate.
