Readily biodegradable (according to OECD criteria).
Several studies for testing ready
biodegradability of iso-butanol carried out (according to OECD guideline
301A, C, D, E and F). The results shows consistently that iso-butanol is
readily biodegradable in water.
iso-butanol degraded in a
range of 70-80 %
(BOD/ThOD) after 28 days according to OECD 301D (closed bottle test)
guideline study [Waggy & al., 1994]. Furthermore
the biodegradation reached 90-100 % (BOD/ThOD)
after 14 days according to OECD 301C guideline [MITI,
1992]. In conclusion iso-butanol is readily biodegradable according to
