In this study, nanoporous silica aerogel and silica aerogel-activated carbon composites have been synthesized using a water glass precursor by cost effective ambient pressure drying method. Equilibrium and kinetics of benzene and ethyl benzene adsorption on silica aerogel and its composites have been measured in a batch mode at tree weights of adsorbent. For the first time, the experimental dat...

in this study, b12n12 nano ring has been selected because it consist of four 6-side rings and polar bonds b-n which in comparison with non-polar bonds c-c, is more suitable for the study of the absorption of other compounds. so reactivity and stability of benzene alone and in the presence b12n12 nano ring field checked. to determine the non-bonded interaction energies between benzene and b12n12...

In the title compound, C(16)H(15)NO, the dihedral angle between the outer benzene rings is 51.88 (6)°, and each of the central six-membered rings has a boat conformation. The hy-droxy and amino groups are syn, and the hy-droxy H atom forms an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules assemble via C-H⋯O and C-H⋯π inter-actions, consolidating a three-dimensional architecture.

In the title compound, C(17)H(14)ClN(5), two C atoms and their attached H atoms of the pyrrolidine ring are disordered over two sets of sites with an occupancy ratio of 0.638 (10):0.362 (10). The benzene and pyridine rings are inclined to one another by 60.57 (8)°. In the crystal, the amino group forms an N-H⋯N hydrogen bond with one of the cyano groups, linking the mol-ecules into chains along...

In the title compound, C(25)H(27)N(7)O(2)·H(2)O, the bis-[4-(dimethyl-amino)-benzyl-idene]pyridine-2,6-dicarbohydrazide mol-ecule and the water mol-ecule are located on a twofold rotation axis. The benzene and pyridine rings form a dihedral angle of 17.13 (7)°. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a two-dimensional supermolecular structure para...

In the title salt, C(6)H(8)N(4)S(2) (2+)·2C(7)H(4)NO(4) (-), the diprotonated diamino-bithia-zole dication is located on an inversion center. The carboxyl-ate group of the anion is twisted with respect to the benzene ring, with a dihedral angle of 13.6 (4)°. N-H⋯O hydrogen bonds involving the amino and ammonium groups of the dication and the carboxyl-ate functionality of the anion generate supr...
