Hi Everyone,
We're currently extracting lignin from modern plant material for d13C
measurement. Previously, we've undertaken digestion in 72% H2SO4, followed
by sequential treatment in 2:1 benzene:ethanol (by volume), ethanol and
distilled water solutions within a Soxhlet apparatus (TAPPI, 1987).
However, I don't like using benzene and was wondering whether any users have
alternatives to suggest? Anything would be a great help.
Many thanks in advance.
Best wishes,
Chris
