Molecular mass distribution of modified coal extract

The chloroform soluble portion of dimethylacetamide extract from a subbituminous coal was subjected to different types of chemical modification i.e. reduction, reductive alkylation, non-reductive alkylation, ‘ionic’ oxidation with subsequent alkylation, etc. The products of the reactions were studie...

Description
Summary:The chloroform soluble portion of dimethylacetamide extract from a subbituminous coal was subjected to different types of chemical modification i.e. reduction, reductive alkylation, non-reductive alkylation, ‘ionic’ oxidation with subsequent alkylation, etc. The products of the reactions were studied by spectral and Chromatographic methods. An increase in molecular mass, prevailing over degradation, was registered by gel permeation chromatography (g.p.c.) analysis.
