English. The obtained results indicate that the important information for structural studies of humic substances can be obtained using different alkylation procedures. From the several alkylation procedures the derivatization with alkyl sulfates can be recommended as giving the highest yields of the reaction products and possibly less affecting the substrate structure. In the alkylation process humic derivatives can be obtained, possessing rather homogenous molecular weight distribution and correspondingly low dispersion index value.
