Direct amidation of fattyacids with long-chain amines was successfully performed by mesoporous silica MCM-41, which showed the highest catalytic activity among other used homo- and heterogeneous catalysts. It was found that MCM-41 can be easily recovered from the reaction mixture followed by simple calcination treatment and reused without loss of its catalytic activity.
