materials. Oxidizing materials such as nitric acid can attack product. The severity can
vary from slight degradation to an explosive reaction.
Hazardous Decomposition Products: Burning produces normal products of
combustion, such as carbon monoxide, carbon dioxide, and water. Aldehydes. Alcohols.
Ethers.

Section XII - Ecological Information
Material is readily biodegradable. Passes OECD test(s) for ready biodegradability. The
rate constant for the vapor phase reaction with photochemically produced hydroxyl
radicals at 25C is estimated to be : 8.32E-12 cm2/molecule- sec. Biodegradation reached
in Modifed OECD Screening Test (OECD Test No. 301 E) after 28 days: >90%.
Biodegradation reached in Manometric Respirometry Test (OECD Test No. 301F) after
28 days: >94%.

Bioconcentration potential is low (BCF < 100 or Log Pow < 3). Henry’s Law Constant
(H) is: 8.05E-9 atm-m3/mol. Bioconcentration factor (BCF) in fish is: 10. Potential for
mobility in soil is very high (Koc between 0 and 50). Soil organic carbon/water partition
coefficient (Koc) is estimated to be: 1. Theoretical Oxygen Demand (THOD) –
calculated: 1.29 mg/mg.
Octanol/Water Partition Coefficient – Measured: -1.36
