✦ Synopsis
The photoreduction of the title compounds by triethylamine in toluene and ethanol was found to originate via formation of an exciplex between the lowest triplet anthraquinones and triethylamine. This complex changed to a contact ion pair followed by proton transfer, generating anthrasemiquinone radicals and triethylamine radical.

## Abstract **BACKGROUND:** Scrubbing using an organic solution instead of an aqueous solution could be a useful way to improve the removal of hydrophobic compounds. Absorption of toluene, dimethyldisulfide (DMDS) and dimethylsulfide (DMS) in an organic solution (di‐2‐ethylhexyladipate—DEHA), follo
The rate constants for the protonation of "free" (that is, solvated) superoxide ions by water and ethanol are equal to 0.5-3.5 X lO-~M-l.s-' in DMF and AN at 20'. It has been found that the protonation rates for the ion pairs of 0; with the BudN+ cation are much slower than those for "free" 0,. It i
