Description Fischer Esterification: This process is the treatment of an alcohol with carboxylic acid in thepresence of inorganic mineral acid catalyst (Furuta, Fukuyama and Ryu, 2017). The usedconditions involve using an acidic catalyst to initiate the nucleophilic attack and formation ofaqueous layer where it gets disposed off in the sink.Tischenko: This is chemical reaction between aldehyde and alkoxide producing esters inpresence of catalysts. Conditions include redox reactions.Avada (alkylation of acid): This takes place by adding photons to a carbonium ion with doublebonds. Herein Identification of impurities in ethyl acetate (ethyl ethanoate)IR: This is useful by using the differential infrared spectroscopy. Here the ethyl acetate would betaken in the small china dish and placed in the machine where the spectrum is received onperiodical manner and the purity is measured in the form of stored spectrum which is digitallysubtracted from the sample.Gas Chromatography: This contains stationary and a mobile phase where separation of complexmixtures takes place (Nasrollahi and et.al., 2019). Here ethyl acetate is mixed with acetic acidand ethanol in equal mixture and later plunger is put and the entire process occurs includingheating, centrifuging, concentrating, cooling and drying with sodium sulfate. For morepurification, chromatography column is inserted and receiving the IR spectrum.Karl Fischer titration: This is the standardised titration procedure to measure the water amountpresent in ethyl acetate. Herein the acidic titration will be conducted by adding iodinemechanically with the sample using a KF reagent. The samples are dissolved in a solvent beforethe beginning of titration. 1
