abstract: Preparation of Ni/bentonite acid activated using a reducing agent from dragon
fruit peel extract (Hylocereus polyrhizus) and its application in the synthesis of one
pot system menthol from citronellal has been carried out. The aims of this study
were to characterize acid-activated Ni/Bentonite using reducing agents of dragon
fruit peel extract based on FTIR spectrophotometry and X-ray diffraction
characterization based on XRD diffractograms and to analyze the product produced
in the synthesis of one pot system menthol from citronellal using acid-activated
Ni/bentonite catalyst.
The catalyst of Ni/Bentonite acid activated was synthesized by the wet
impregnation method with the addition of dragon fruit peel extract as a natural
reducing agent. Acid-activated Ni/Bentonite was successfully synthesized based on
the help of the FTIR spectrum with absorption at wavelengths of 1049.28 cm-1 and
694.37 cm-1 which indicated the Si-O group in bentonite and the XRD
diffractogram indicated the presence of Ni at the absorption peak of 2
