SULFURIC ACID 95-98% A.C.S. REAGENT (C005B-078449)

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
