Nitration of phenols
WebbPhenol is nitrated selectively by dilute nitric acid over alumina and a remarkable ortho-selectivity is observed in liquid phase nitration. Highlights i. The solid acid catalyst (Gamma-alumina) was prepared by control precipitation method. ii. Phenol was selectively nitrated in liquid phase using dilute nitric acid (30%) in presence γ-alumina. iii. WebbNitration of phenol itself can be easily achieved under milder conditions using dilute nitric acid in chlorinated solvent in reasonable combined yield (61%) with a 1:2.3 ratio of...
