… In the present work, we report the esterification of ,-unsaturated acids, aliphatic acids and
heterocyclic aromatic acids with ethanol and methanol using a mixed catalyst, Fe2(SO4)34H2O
/ concentrated H2SO4. This catalytic process has an efficient catalytic ability and gives
excellent esterification yields in short reaction times. … In Table 2, we list the esterification
results of 4 acids with methanol or ethanol using the mixed catalyst, Fe2(SO4)34H2O /
concentrated H2SO4(molar ratio=2:1), which are compared with the corresponding …
