| Application: | Sulfuric acid can be used as a catalyst: • In the hydrolysis of primary or secondary nitroalkane salts to aldehydes or ketones. • In the selective hydrolysis of nitriles to amides. • To synthesize amides of t-alkylcarbinamines via Ritter reaction between nitriles and alkenes. • To prepare 3,4-dialkyl-2(5H)-furanones by carbonylation of α,β-unsaturated aldehydes. • In the nitration of aromatic carbocycles and heteroaromatic compounds. • In the Friedel–Craft ketone synthesis using anhydrides via α-amidoalkylation reaction. H2SO4 can also be used in the following reactions: • Michael′s addition reactions • Electrophilic substitution reactions • Esterification of highly hindered aromatic acids • Aldol condensation reaction • Beckmann rearrangement • Hofmann–Loffler–Freytag reaction • Isomerization • Dehydrogenation • Sulfonation |
