Abstract

In this study, ammonium hydrogen sulfate immobilized on Luffa fruit (AHS@L) as an effective and biodegradable solid acid catalyst was synthesized by acidification of Luffa fruit via a new method. The synthesized catalyst was characterized by TGA, SEM, XRD and FTIR. The FT-IR analyze approved the acidification of the Luffa surface by hydrogen sulfate moieties. Also the XRD analyze clearly show the change in the morphology of Luffa after acidification. The TGA analyze show the heat resistance of the catalyst up to 245 ° C and the FESEM images clearly showed that the catalyst surface was hydrated as a result of acidification. The synthesized catalyst was used to protect the amines in the N-tert butyl carbamate reaction under solvent-free conditions at room temperature. Different types of aliphatic and aromatic amines have been produced as related monocarbamates with excellent yields and short reaction times. This method was mild and selective and has advantages such as heterogeneous catalysis, low cost and catalyst recovery capability.
