CH3COOC6H5 ( phenyl axetat) + 2NaOH → CH3COONa + C6H5ONa + H2O (1).
CH3COOCH2-CH=CH2 (anlyl axetat)+ NaOH → CH3COONa + CH2=CH-CH2OH (2).
CH3COOCH3 (metyl axetat) + NaOH → CH3COONa + CH3OH (3).
HCOOC2H5 (etyl fomat) + NaOH → HCOONa + C2H5OH (4).
C3H5(OOCC15H15)3 ( tripanmitin) + 3NaOH → C3H5(OH)3 + 3C15H31COONa (5).
HCOOCH=CH2 + NaOH → HCOONa + CH3CHO (6).
