Half-lives for the di-propylene glycol ethers ranged from 5.2 to 7.6 h, averaging 6.5 h.
The method of Atkinson (1987) was used with the EPIWIN program to
estimate photo-oxidation half-lives based on reaction with hydroxyl
radicals. Assuming a concentration of hydroxyl radicals of 1.5 X
10000000 molecules/cm3 and a 12h daylight period, a range of half-lives
was calculated. Half-lives for the di-propylene glycol ethers ranged
from 5.2 to 7.6 h, averaging 6.5 h.
