Synthesis of isoamyl acetate by amberlyst 15 in solvent-free system by different novel esterification methods

Isoamyl acetate finds many applications in food, cosmetic and pharmaceutical industries as a flavor and fragrance compound. The current work focuses on different novel esterification methods catalyzed by amberlyst 15 under solvent-free system. Physical characteristic of the catalyst which was used indifferent esterification methods studied by scanning electron microscopy and the result show that the surface area of amberlyst 15 under ultrasound was fully denatured. The results of this study introduced microwave as rapid, economical, and environmentally friendly esterification methods. Microwaveassisted esterification is an advanced technique utilizing microwave heating process and could be considered as a novel method for the esterification of isoamyl alcohol and acetic acid. One of the major problems with traditional methods is long reaction time with low yield
