Title Synthesis of metyl acetate and heptyl acetate using methanol 1 heptanol and acetic acid over acidic alumina and Amberlite IRA 120 Author S Salehi Supervisors Prof A H Dabbagh Department ChemistryAbstract In current project firstly to achieve a suitable catalyst for esterification reaction In thefirst stage alumina physical and chemical was mixed with a number of differentAmberlite and reaction between methanol with acetic acid and acetic acid with 1 heptanolwas carried out The synthetic catalysts was identified using the FESEM FTIR and XRDmethods and then reacted with methanol and acetic acid at the ratio of 4 1 at reflux systemat temperatures of 0 0 and 70 C to achieve the synthesis of methyl acetate andexamine the catalyst performance using gas chromatography GC mass In the next step to synthesize the heptiyl acetate is mixed the acetic acid with the ratio of 1 1 and 1 2 with1 heptanol over alumina and amberlite IRA 120 catalyst at temperatures of 70 100 and130 C Then the efficiency and extent of reactions was determined using GC mass Finally the optimum conditions temperature and reaction time and chatalyts were selectedfor both products Keywords alumina Amberlits Ester Heptiyl acetate Methyl acetate synthesis
