Abstract

The initial brown coals, humic substances and their fractions obtained from them, as well as bitumen were characterized using technical and elemental analysis, Fourier infrared, 13C NMR spectroscopy. The component composition of the obtained bitumen and its fractions was studied using the chromatography-mass spectrometry method. It has been established that during the fractionation of humic substances, the main part of aromatic compounds is concentrated in humus acids. The data on the study of the phytostimulating activity of various fractions of humic substances and their mixtures with the saponified component of the resin of extraction bitumen, in relation to wheat seeds of the Aphrodite variety, are presented. A positive eff ect on the growth performance of the studied fractions of humic substances separately and when used together in a mixture with the saponified component of bitumen resin was shown. The phytoactivity index (PI) of the studied initial samples and their mixtures is in the range of 1.04–1.64.

褐煤腐殖质提取树脂和馏分的成分与性质
利用技术和元素分析、傅立叶红外光谱、13C NMR 光谱对初始褐煤、腐殖质及其馏分以及沥青进行了表征。使用色谱-质谱法研究了所得沥青及其馏分的成分组成。结果表明,在腐殖质的分馏过程中,芳香族化合物主要集中在腐殖酸中。研究数据介绍了各种腐殖质馏分及其与沥青提取树脂皂化成分混合物对阿芙罗狄蒂品种小麦种子的植物刺激活性。结果表明,单独使用所研究的腐殖质馏分以及将其与沥青树脂的皂化成分混合使用,都会对小麦的生长性能产生积极影响。所研究的初始样品及其混合物的植物活性指数(PI)在 1.04-1.64 之间。
