Additional information

Adsorption / desorption

Parent compound isobutyryl chloride and hydrolysis product isobutyric 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 chlorid in aqueous solutions.

Henry`s Law constant

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

Hydrolysis product isobutyric 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 cpmpound isobutyryl chloride: Over time, the substance will preferentially distribute into the compartments water (18.1%) and air (81.8%).

However, model calculation may be of low relevance as the compound rapidly decomposes in water (t1/2< 10).

Hydrolysis product isobutyric acid: Over time, the substance will preferentially distribute into the compartments water (95.7%) and air (4.21%).
