Adsorption / desorption

Parent compound butyryl chloride and hydrolysis product butyric acid: Adsorption to solid soil phase is not expected.

However, the assessment of the adsorption potential of the parent compound may be of low relevance, due to the rapid hydrolysis of the acid chloride in aqueous solutions.

Henry`s Law constant

Parent compound butyryl chloride From the water surface, the substance will rapidly evaporate into the atmosphere.

Hydrolysis product butyric acid From the water surface, the substance will not evaporate into the atmosphere.

However, the assessment of the volatility of the parent compound may be of low relevance due to the rapid hydrolysis of the acid chloride in aqueous solutions.

Distribution modelling

Parent compound butyryl chloride: Over time, the substance will preferentially distribute into the compartments water (28.7%) and air (71.2%).

However, the model estimation may be of low relevance due to the rapid hydrolysis of the acid chloride in aqueous solutions.

Hydrolysis product butyric acid: Over time, the substance will preferentially distribute into the compartments water (89.9%) and air (10.0%).
