Hydrolysis

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): In contact with water the substance will hydrolyse rapidly.

Hydrolysis product 3,5,5-trimethylhexanoic acid (CAS 3302-10-1): According to structural properties hydrolysis is not expected/probable.

 

Phototransformation in air

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.

Hydrolysis product 3,5,5-trimethylhexanoic acid (CAS 3302-10-1): After evaporation or exposure to air, the substance will be slowly degraded by photochemical processes.

 

Biodegradation

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): The substance is considered moderately/partly biodegradable according to OECD criteria. Furthermore, the substance rapidly hydrolyses to form 3,5,5-trimethylhexanoic acid (CAS 3302-10-1).

Hydrolysis product 3,5,5 -trimethylhexanoic acid (CAS 3302-10-1): ready biodegradable according to OECD criteria.

 

Bioaccumulation

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): significant accumulation in organisms is not to be expected.

Hydrolysis product 3,5,5 -trimethylhexanoic acid (CAS 3302-10-1): significant accumulation in organisms is not to be expected.

 

Adsorption

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): Due to rapid hydrolysis, 3,5,5-trimethylhexanoyl chloride will not be present in the environment for a significant time. Therefore, the fate in the environment is mainly based on the hydrolysis product 3,5,5-trimethylhexanoic acid.

Hydrolysis product 3,5,5 -trimethylhexanoic acid (CAS 3302-10-1): Adsorption to the solid soil phase is not to be expected.

 

Henry's Law Constant

Parent compound 3,5,5-trimethylhexanoyl chloride (CAS 36727-29-4): Due to rapid hydrolysis, 3,5,5-trimethylhexanoyl chloride will not be present in the environment for a significant time. Therefore, the fate in the environment is mainly based on the hydrolysis product 3,5,5-trimethylhexanoic acid.

Hydrolysis product 3,5,5 -trimethylhexanoic acid (CAS 3302-10-1): From the water surface the substance is not expected to evaporate into the atmosphere.
