Post Lab Report Format (typed, printed, page numbered, single spacing) (make sure to put Your Name and Your Partner’s Name together)Title (n-Butyl Acetate by Azeotropic Distillation of Water)Purpose (why we did the exp.)Chemical Structure (make sure to put the reference) You can draw your own structure with free software (any chemical structure drawing software is ok. However, put the name of the software below the structures)Safety Information/Physical Data (physical properties of compounds)Procedure (Your own paragraph form (3rd person))Clean-Up (how to clean up the wastes)Observational Data PresentationFinal mass of n-Butyl Acetate? Color of the product? IR? Briefly explain IR of the product. (See the attached IR in this announcement) % yield?Discussion (in PARAGRAPH FORM)Le Chatelier’s principle? How do Acetic acid and 1-butanol react? Why Dowex ion-exchange resin? Dean-Stark azeotropic esterification apparatus?Why 3 M sodium hydroxide solution (NaOH)? Why aqueous sodium chloride solution (brine)? sodium sulfate (Na2SO4)?Explain IR data. Any possible error?References (ACS format for discussion)Side reaction: N/A% yield: show your calculation work.Mechanisms: N/AAnalysis of TLC/IR/NMR: show the IR again and explain the IR of n-Butyl Acetate in detail.Post Lab Questions: N/AChapter 40: Exp. 1 n-Butyl Acetate by Azeotropic Distillation of Water O OOHDowex ion-exchange resin+ + H2OOH ©Dr. Wang O
