CnH2nO2+Cn'H2n'+2O---> H2O+ CnH2nOOCn'H2n'
M,ester= 12(n+n')+2(n+n')+32 g/mol
14(n+n')+32 gester................................32gO
100g................................................36,36g
3200= 509(n+n')+1163,5
n+n'= 4 sunt trei posibilitati
n=1 acid metanoic n'=3 alcool propilic---> ester-metanoat de propil
n=2 acid etanoic n'=2 alcool etilic --> ester- acetat de etil
n=3-acid propionic n'=1 alcool metilic--> ester -propionat de metil
