Descrizione

Descrizione generale

2-Propanol (i-PrOH), a renewable secondary alcohol,[1] is water soluble, colorless, volatile liquid with a sweet odor.[2] It is a potential substitute to petroleum-derived gasoline.[1] Preparation of methyl isobutyl ketone (MIBK) using 2-propanol as the precursor has been reported with yield as high as 25%.[3] Solubility of benzoic acid has been investigated in 2-propanol by gravimetric method in the temperature range, 277-346K.[4] Its photocatalytic degradation has been examined by various methods.[5][6][7]

Applicazioni

2-Propanol may be used in the following processes:

• As a solvent in the synthesis of di- and trisubstituted ortho biaryls by Suzuki-Miyaura cross-coupling reaction.[8]
• As an alternate solvent to benzene in the analysis of total carbonyl compounds in heated and frying oils.[9]
• As a reaction medium in the preparation of cyclic ureas by reacting CO₂ with diamines in the presence of pure cerium oxide (CeO₂).[10]
