Synthetic polyfunctional ionites

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.
