1-Bromodecane (98%),
1-bromododecane (97%),
1-bromotetradecane (97%),
1-bromohexadecane (97%),
1-bromooctadecane(97%), and
3-pyridinecarboxamide (nicotinamide, 98%) were purchased
from Sigma-Aldrich (Saint Louis, Missouri). 2,4-Dichlorophenoxyacetic
acid (2,4-D, 98%) and 4-chloro-2-methylphenoxyacetic acid (MCPA, 96%)
were obtained from PESTINOVA (Jaworzno, Poland). Both herbicidal acids
were purified prior to use by recrystallization from toluene followed
by treatment with
activated carbon (powder—100 particle size
(mesh), Sigma-Aldrich, Saint Louis, Missouri). All solvents (methanol
(99.8%), dimethyl sulfoxide (DMSO) (98%), acetonitrile (99%), acetone
(99%), isopropanol (98%),
n-propanol (99.5%), ethyl
acetate (99%), chloroform (98%), toluene (99.5%), hexane (99.5%))
and potassium hydroxide (85%) were delivered by Avantor (Gliwice,
Poland) and used without further purification. Deionized water with
a conductivity < 0.1 μS cm
–1, from the
HLP Smart 1000 demineralizer (Hydrolab, Poland), was used.
