Endpoint summary
Administrative data
Description of key information
- very low potential to hydrolyze
- phototransformation water/soil: no potential to undergo photolysis in water or soil
- phototransformation air: estimated half-life of maximum 4.38 days (linear and branched C4 -C10, QSAR calculation) --> residence times in the atmosphere are relatively short.
Additional information
Hydrolysis
Hydrolysis is a reaction in which a water molecule or hydroxide ion substitutes for another atom or group of atoms present in a chemical resulting in a structural change of that chemical. Potentially hydrolyzable groups include alkyl halides, amides, carbamates, carboxylic acid esters and lactones, epoxides, phosphate esters, and sulfonic acid esters. The lack of a suitable leaving group renders compounds resistant to hydrolysis.
The chemical constituents that comprise 'Naphtha (Fischer-Tropsch), light, C4-10 - branched and linear' consist entirely of carbon and hydrogen and do not contain hydrolysable groups. As such, they have a very low potential to hydrolyse. Therefore, this degradative process will not contribute to their removal from the environment.
Phototransformation
The direct aqueous photolysis of an organic molecule occurs when it absorbs sufficient light energy to result in a structural transformation. Only light energy at wavelengths between 290 and 750 nm can result in photochemical transformations in the environment, although absorption is not always sufficient for a chemical to undergo photochemical degradation In general, most representatives of Naphtha (Fischer-Tropsch), light, C4-10 - branched and linear will not undergo direct photolysis. Saturated hydrocarbons, which constitute the majority of the test item, do not absorb appreciable light energy above 290 nm. Therefore, this fate process will not contribute to a measurable degradative removal of chemical components in this category from the environment. Indirect photodegradation via reaction with hydroxyl radicals may be important in the gas-phase degradation of the respective hydrocarbons that volatilize to the troposphere. An overall range of half-lives expected for individual, linear components is from 0.963 to 4.064 days and for respective, branched components is from 0.939 to 4.38 days, respectively. Finally, residence times in the atmosphere are relatively short
