General description

Isopropyl alcohol (2-Propanol, i-PrOH), a renewable secondary alcohol, is water soluble, colorless, volatile liquid with a sweet odor. It is a potential substitute to petroleum-derived gasoline. The preparation of methyl isobutyl ketone (MIBK) using i-PrOH as the precursor has been reported with yield as high as 25%. The solubility of benzoic acid has been investigated in i-PrOH by gravimetric method in the temperature range, 277-346K. Its photocatalytic degradation has been examined by various methods. This product is a high quality pharmacopoeia product that meets the testing specifications of USP (United States Pharmacopoeia). It can be employed in research and pilot studies.
