Abstract:
It is presented the results of reaction of a nucleophilic replacement of the chlorine humic acids
with various
nucleophiles. It is shown that reactions proceed on aliphatically bound atom of chlorine and lead
to formation of functional derivative coals of molar structure 1:1–2 (HU:Nu). It is established
that 60–70 % bound coal chlorine participate in reaction with nucleophiles. Depending on conditions
of reaction and the applied rea-
gents on nucleophilic groups 30–50 % of chlorine are replaced.
