Preparation of Octanoic acid: it can be prepared by octanoyl chloride. The other product is octanoic acid octyl ester. This reaction will need reagent LiInH4 and solvent diethyl ether. The reaction should react in temperature of 0 °C for 1 hour and in the room temperature for 12 hours. The yield is about 22%.
Uses of Octanoic acid: it is used commercially in the production of esters used in perfumery and also in the manufacture of dyes. And it is also used in the treatment of some bacterial infections and used as an algaecide, bactericide, and fungicide in nurseries, greenhouses, garden centers, and interiorscapes on ornamentals. Moreover, it is also used as disinfectant in health care facilities, schools/colleges, animal care/veterinary facilities, industrial facilities, office buildings, recreational facilities. In addition, it can be used to get octan-1-ol. This reaction will need reagents Sm and 10percent HCl and solvent methanol. The reaction time is 30 minutes with ambient temperature. The yield is about 39%.
