Pemanfaatan Furfural dari Limbah Pabrik Gula (Ampas Tebu) Untuk Sintesis Asam-β-(2-furil) Akrilat Sebagai Bahan Dasar Alternatif Senyawa Tabir Surya
ABSTRACT: The research of the
usefullness of furfural from bagasse for the production of β-(2-furyl)-acrilyc
acid as an alternative raw material of sunscreen compound had been done. The
research was done on two stages, the first stage was synthesis of furfural from
bagasse and the second was synthesis of β-(2-furyl)-acrilyc acid that is an
analog of cynnamic acid in which some derivatives are known possess activities
as sunscreen. Cynnamic acid could be produced from benzaldehyde by Perkin
methods using alkali hydrolysis. With the similarity of the main structure, so
β-(2-furyl)-acrilyc acid can also be synthesized from furfural by Perkin
method. The β-(2-furyl)-acrilyc acid had been synthesized in this research from
furfural isolated from bagasse by NaOH hydrolysis. Synthesis was done by reflux
for 2 hr at 140 - 145 oC and 3 hr at 145 - 150 oC. From the spectroscopic data
its known that furfural could be produced from bagasse in 11.65 % yield and
33.83% of β-(2-furyl)-acrilyc acid from the synthesis on the second process.
The UV -Vis spectrophotometer analysis result of β-(2-furyl)-acrilyc acids
showed λmax at 296.20 nm. It showed that until this step the sunscreen compound
can be resulted from furfural isolated from bagasse, especially as a sunscreen
that protected skin from eritema (λmax at 290 - 320 nm) that is called as
sunscreen UV-B.
