- Synthesis of menthol (CWH100) from citronellal (CIIH",O) has been performed by a one-pot process. The process was conducted in a 250 mL capacity auloe/al'e wilh acidified nalural =eolite and Raney Nickel as catalYSIS at temperature 120°e. pressure 5 bar, and varialion of time 1-8 hours. Natural =eolite and Raney Nickel were placed in the aUloc/aI'e and it was found Ihat Ihe cye/isalion and hydrogenation reaclion 10 form menthol could undergo in the same reactor. FTJR Analysis showed peak formation at 3346.50 cm-' indicating OH group was formed Result of I H-NMR and /3C-NMR analysis reports chemical shifts at 6= 71. 53 ppm and ,)=4.05 ppm. Gas chromatography analysis showed thaI the com'ersiol1 was 80% with concentration ofmenthol about 68% (v/v).
