Propanol, also called propyl alcohol, is a colorless alcohol used as a solvent in the manufacture of various chemicals. Propanol exists as two isomers. Normal propanol (CH₃CH₂CH₂OH) is a by-product of the synthesis of methanol (methyl alcohol). Propan-2-ol (isopropyl alcohol), (CH₃)₂CHOH, is a secondary alcohol which is easily oxidized to propanone (acetone).
