Isobutanol can corrode aluminum at

temperatures above 60°C. Conse-

quently, it should never be stored,

except at low temperatures, in tanks

constructed from aluminum and its al-

loys.

If severe demands are imposed on

the quality of the isobutanol, we rec-

ommend that it be stored in stainless

steel (e.g. 18Cr 9Ni) tanks.

Drums containing the product should

be kept tightly closed in a well-venti-

lated place.

Always refer to the Material Safety

Data Sheet (MSDS) for detailed

information on handling and disposal.
