| description | Derivatization of cardanol by methylation, epoxydation and oxidation has been
studied. Cardanol is one component of cashew nut shell liquid (CNSL), which is
obtained as a by-product of the cashew industry.
Cashew nut shell liquid extraction was performed by mechanical press followed
by characterization of the liquid with IR spectrophotometer and GC-MS. Then, the
technical CNSL was heated at 130-135
o
C for 3 hours to give decarboxylated CNSL.
Cardanol was isolated from decarboxylated CNSL by the use of methanol and
ammonium hydroxide (8:5) and extracted with n-hexane. Methylation of cardanol
was carried out by DMS and DMC to give methyl cardanol. Methyl cardanol was
epoxidized by mCPBA at 0
o
C for 3 hours, while oxidation was conducted to the
double bond of methyl cardanol by aqueous KMnO4 in neutral and alkaline
conditions in the presence of CTAB and TBAB as phase transfer catalyst (PTC). All
of the products were characterized by IR spectrophotometer and GC-MS.
CNSL contains anacardic acid ( 39%), cardol (27%), and cardanol (9%), while
decarboxylated CNSL contains cardanol and cardol in 87 and 12%, respectively.
Then, cardanol was isolated in 76% yield from decarboxylated CNSL. Methylation
of cardanol by DMS (55%) gave a good yield than DMC (11%). Oxidation of methyl
cardanol with aqueous KMnO4 and TBAB in alkaline media gave a cleavage product,
an aldehyde (10% yield), while CTAB yielded carboxylic acid in 8%. In addition, the
same oxidation in neutral condition in the presence of TBAB produced a carboxylic
acid in 11% yield. |
