| Abstract: | Acid activated
Indian bentonite (AAIB) is an excellent catalyst for the esterification of long
chain fatty acids with long chain alcohols. The ester constituents of
spermaceti (whale wax) and an analogue of jojoba oil are obtained when the
reactants with catalyst are exposed to microwave irradiation under solvent-free
conditions. The Indian bentonite is used for such a reaction for the first
time. The procedure is essentially pollution-free as virtually no waste
material is produced. Esters can also be synthesized by solvent-free
alkylations of carboxylic anions under microwave irradiation. A few
solvent-free alkylations of carboxylic anions have been reported using
tetrabutylammonium bromide (TBAB) as a phase transfer catalyst under microwave
irradiation. |
