摘要

Abstract

Acylation of 2-methylnaphthalene (2-MN) is a very important reaction in organic synthesis

and the effiency of the continuous reactor is more than one of the batch reactor. Considering that the Friedel-Crafts acylation is a rapid exothermic reaction

in this study

we perform the acylation of 2-MN in a stainless steel microchannel flow reactor

which is characterized by high mass and heat transfer rates. The effect of reactant ratio

mixing temperature

reaction temperature

and reaction time on product yield and selectivity were investigated. Under the optimal conditions

2-methyl-6-propionylnaphthalene (2

6-MPN) was obtained in 85.8% yield with 87.5% selectivity. Compared with the conventional batch system

the continuous flow microchannel reactor provides a more efficient method for the synthesis of 2

6-MPN.
