calculated data for representative constituents of Alchisor TAL 123:
Hydrocarbons C11-C14, n-alkanes, isoalkanes, cyclics, aromatics (2-25%)
and undecan-1-ol are available.
C11-C14, n-alkanes, isoalkanes, cyclics, aromatics (2-25%)
the case of Hydrocarbons C11-C14, n-alkanes, isoalkanes, cyclics,
aromatics (2-25%), indirect photochemical degradation of these
hydrocarbons as mediated by OH-attack, is estimated to have a half-life
of 0.09 to 1.43 days, or 1.10 to 17.25 hours,
based on a 12-hour sunlight day, a rate of 7.4×10-12to 116.3×10-12cm3/mol/sec,
and an average OH-concentration of 1.5×106OH/cm3.
A 12-hour day half-life value normalizes degradation to a standard
daylight period during which hydroxyl radicals needed for photolysis are
generated in the atmosphere.
The rate constant of photodegradation in air for
undecan-1-ol has been estimated using the SRC AOPWIN program. Using this
program, undecan-1-ol is estimated to have a half-life of 22.9 hours and
a rate constant of 16.78136E-12 cm3/mol/sec assuming an
OH radical concentration of 5x105mol/cm3.Branched components, present in the substance within the limits described in section 1.1-1.4, may be photodegraded slightly faster than linear components of equivalent carbon number.
The reported half-life therefore
represents a reasonably conservative estimate for this substance.
no calculated data is available for the Alchisor TAL 123 constituent,
