The Uses of Dibutyl oxalate
Dibutyl oxalate has been suggested for use in perfumes as a solvent blender, but does not seem to offer advantages over odorless or low-odor solvents conventionally used.
Definition
ChEBI: Oxalic acid dibutyl ester is a dicarboxylic acid.
General Description
The rate of dibutyl oxalate degradation in ruminal contents from adapted and non-adapted animals was studied.
Synthesis
Dibutyl oxalate is produced from n-Butanol and Oxalic acid by direct esterification.
