EC number: 265-191-7
CAS number: 64742-88-7
A complex combination of hydrocarbons obtained from the distillation of crude oil or natural gasoline. It consists predominantly of saturated hydrocarbons having carbon numbers predominantly in the range of C9 through C12 and boiling in the range of approximately 140°C to 220°C (284°F to 428°F).
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 (Neely
and Blau, 1985). The lack of a suitable leaving group renders compounds
resistant to hydrolysis.
chemical constituents that comprise the kerosine category consist
entirely of carbon and hydrogen and do not contain hydrolyzable groups.
As such, they have a very low potential to hydrolyze. Therefore, this
degradative process will not contribute to their removal from the
available data and available weight of evidence demonstrate that
kerosines are resistant to hydrolysis because they lack a functional
group that is hydrolytically reactive. Therefore, this fate process will
not contribute to a measurable degradative loss of these substances from
the environment. Further testing is not required under Annex XI, section
tests for atmospheric oxidation half-lives are intended for single
substances and are not appropriate for this complex substance. However,
this endpoint is characterized using quantitative structure property
relationships for representative hydrocarbon structures that comprise
the hydrocarbon blocks used to assess the environmental risk of this
substance with the PETRORISK model (see library tab in PETRORISK
spreadsheet attached to Section 13).
in water and soil:
direct photolysis of an organic molecule occurs when it absorbs
sufficient light energy to result in a structural transformation. The
absorption of light in the ultra violet (UV) -visible range, 110-750 nm,
can result in the electronic excitation of an organic molecule. The
stratospheric ozone layer prevents UV light of less than 290 nm from
reaching the earth's surface. Therefore, only light at wavelengths
between 290 and 750 nm can result in photochemical transformations in
the environment. A conservative approach to estimating a photochemical
degradation rate is to assume that degradation will occur in proportion
to the amount of light wavelengths >290 nm absorbed by the molecule.
This substance contains hydrocarbon molecules that absorb UV light below
290 nm, a range of UV light that does not reach the earth's surface.
Therefore, this substance does not have the potential to undergo
photolysis in water and soil, and this fate process will not contribute
to a measurable degradative loss of this substance from the environment.
