N-{4-[(3-Methylphenyl)sulfamoyl]phenyl}benzamide

In the title compound, C20H18N2O3S, the dihedral angle between the central benzene ring and the amide group is 24.1 (3) and that between this ring and the aromatic ring of the tolyl group is 68.2 (16). In the crystal, adjacent molecules are linked by N—HO hydrogen bonds into a linear chain running along [100]. Weak C—HO contacts also occur. Extensive weak – interactions exist from both face-to-face and face-to-edge interactions occur between the aromatic rings [centroid–centroid distances = 3.612 (2) and 4.843 (2) A˚ ].

Applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon
2023
Hybrid aspens have long attracted scientific interest, but the research on their use as feedstocks for chemical applications are still very limited. The bark biomass of the poplar species contains many valuable extractives that can be utilized as value-added products. This paper examines the applicability of hybrid aspen (Populus tremula L. × P. tremuloides Michx.) bark extract as a precursor of rigid carbon foam and activated carbon. To explore this, the study considers 1) the basic chemical composition of the bark in terms of added value potential, 2) the basic chemical composition of the bark extract and the effect of its pretreatment on the extract composition, 3) the production of rigi…
