Consumption of isopropanol as a raw material for acetone is declining. Several compounds are synthesized from isopropanol, such as methyl isobutyl ketone and many esters. End-use supplies vary according to the quality of isopropyl alcohol. Anhydrous isopropyl alcohol is 99% of the conventional quality, while the content of special grade isopropyl alcohol is more than 99.8% (for flavors and medicines). For the preparation of acetone, diisopropyl ether, isopropyl acetate, thymol, etc. In many cases, alternatives to ethanol are used.
