Additional information


After evaporation or exposure to the air, the substance and its hydrolysis product CAS 147 -57 -5 will be slowly degraded by photochemical processes.

This estimation refers to dry air. In mist, rain, droplets and aerosols, hydrolysis will be the major fate process of the acid chloride due to the short half-life in aqueous solution. Therefore this estimate may be of low relevance for 2 -ethylhexanoyl chloride.


In contact with water 2 -ethylhexanoyl chloride will hydrolyse rapidly.

Due to rapid hydrolysis, 2 -ethylhexanoyl chloride will not be present in the environment for a significant time. The substance degrades spontaneously in contact with aqueous media. Therefore, the fate in the environment is mainly based on the hydrolysis product 2 -ethylhexanoic acid.


2-Ethylhexanoic acid is readily biodegradable.



For the hydrolysis product 2 -ethylhexanoic acid, significant accumulation in organisms is not to be expected.



Adsorption of the hydrolysis product 2 -ethyhexanoic acid to solid soil phase is not expected.

Henry Law Constant

The hydrolysis product 2 -ethylhexanoic acid will not evaporate into the atmosphere from the water surface.
