Sediments adjacent to a kraft pulp and paper mill on western Nipigon Bay, Lake Superior, were examined for resin acids. Dehydroabietic acid was the predominant resin acid with surficial concentrations of less than 5–100 μg/g.The areal distribution

Water, seston, sediment, and macrophyte samples were collected from Nipigon Bay, Lake Superior at distances up to 6.8 km from the effluent discharge of a kraft pulp and paper mill at Red Rock, Ontario. Fifteen compounds have been identified in mill e

Spectral changes exhibited by 4-hydroxyazobenzene in the 90–100% H2SO4 region are shown to be the result of a sulfonation process, superimposed (above 98% H2SO4) on a second equilibrium protonation. The reaction product is 4-hydroxyazobenzene-4′-

The mechanism of sulfonation of 4-hydroxyazobenzene and of 4-hydroxyazobenzene-4′-sulfonic acid in concentrated sulfuric acid media is examined through rate correlations and comparison is drawn with sulfonation of alkyl- and halogenobenzenes by mea

The temperature coefficient of the enthalpy of activation (ΔCp≠) for the hydrolysis of p-methyl, p-chloro and p-nitro benzyl chlorides have been determined, as well as α-deuterium isotope effects and kinetic solvent isotope effects. These results

Study of the acid-catalyzed Wallach rearrangement of azoxybenzene is extended into the 100% H2SO4 region. The rate of formation of 4-hydroxyazobenzene can be followed spectrally in a straight-forward manner until close to 99% H2SO4, but in higher aci

4-Hydroxyazobenzene and 4-hydroxyazobenzene-4′-sulfonic acid, which are known to be protonated in dilute acid on the azo function, are shown through spectroscopic studies to undergo a second equilibrium protonation in the 100% H2S04 region. The pKa

In relation to the intermediacy of azobenzene-4-hydrogen sulfate in the Wallach rearrangement of azoxybenzene, the potassium salt has been characterized and subjected to examination under acidic conditions. A pKa value of −2.14 has been obtained, f
