| Summary: | The Effect of Alkyl Group in Acetyl Chloride and Butanoyl
Chloride on The Percentage of Ferulic Acid Esterification
(Using Microwave Irradiation)
Frida Putri Nur Islami
4-acetoxy-3-methoxycinnamic acid was synthesized by reacting
ferulic acid and acetyl chloride whereas 4-butoxy-3-methoxycinnamic
acid was made from the reaction of ferulic acid and butanoyl chloride.
This synthesis was carried through the substitution mechanism of
nucleophilic acyl using microwave irradiation. The Optimum percentage
in the synthesis of 4-acetoxy-3-methoxycinnamic acid was observed at
40 watt and 0,5 min.
In order to study the effect of alkyl group length to the
percentage of ferulic acid esterification, acetyl chloride and butanoyl
chloride were used as acyl halides in this research. The result show that
the length of alkyl group in acetyl chloride and butanoyl chloride has no
effect toward the percentage of ferulic acid esterification.
The characterization of 4-acetoxy-3-methoxycinnamic acid and
4-butoxy-3-methoxy cinnamic acid was performed using melting point
test, UV-Vis spectrophotometry, FT-IR spectrophotometry, 1H-NMR
spectrometry. The synthetic percentage of 4-acetoxy-3-methoxycinnamic
acid and 4-butoxy-3-methoxy cinnamic acid were found to be 95,04 % ±
1,70 and 66,37 % ± 4,34, respectively. Both of them show the optimum
reaction at 40 watt and 0,5 min.
