Abstract
A two-step greener catalytic process has been developed for the semi-synthesis of (−)-menthol from citronellal-rich essential oils such as Cymbopogon winterianus and Corymbia citriodora by using novel bi-acidic composites. These novel composites (Al-B-NaYZE or Sn-B-NaYZE) were prepared by impregnation of Sn-B and Al-B over NaYZE framework to increase the Lewis and Bronsted acidic sites. These composites were thoroughly characterized using TDP, FT-IR, UV, XRD, SEM, HRTEM, SA, and TGA. The composite Sn-B-NaYZE cyclized 99% of citronellal to isopulegol isomers with 99% selectivity in 45 min under a liquid CO2 medium, while composite Al-B-NaYZE is showing 95% selectivity towards isopulegol isomers. Sn-B-NaYZE displayed enhanced selectivity due to its higher Lewis and Bronsted acidic characteristics. The chiral study indicated that the Sn-B-NaYZE composite is giving the highest selectivity (94%) towards (−)-isopulegol. (+)-Citronellal or citronella essential oil was found as an ideal substrate for (−)-menthol production. It observed that the Sn-B molar ratio over base material NaY-Zeolite played a major role in catalytic activity and selectivity towards (−)-isopulegol. Further, isopulegol isomers were reduced to 98% of menthol using 1%Pd/AC at 40 psi H2 pressure in 1 h. The reaction mixture was slowly frozen to -40 °C for trouble-free isolation of the crude menthol. Further, pharmaceutical and flavor grade (−)-menthol was purified from the crude menthol through an esterification process. This (−)-menthol was found to be 100% biobased on 14C-radiocarbon-dating to authenticate as nature-identical.
