Dielectric and Thermodynamic Properties of 2, 3-Butanediol + 2-ethyl-1-hexanol Mixtures
Experimental results of dielectric investigations for binary mixtures of 2, 3-butanediol, 2, 3-BD, in2-ethyl-1-hexanol, 2EH, were reported for various mole fractions and temperatures (298.2-308.2) Kand they were used to calculate dielectric parameters such as Kirkwood correlation factor, excesspermittivity and Bruggeman parameter. These parameters were used to carry out temperaturedependent die...
متن کامل1-Ethyl-3-methylquinoxalin-2(1H)-one
The asymmetric unit of the title compound, C(11)H(12)N(2)O, contains two independent mol-ecules. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules. There are π-π contacts between the quinoxaline rings [centroid-centroid distances = 3.446 (2), 3.665 (2), 3.645 (3) and 3.815 (3) Å]. There also exist C-H⋯π contacts between the methyl groups and the quinoxaline rings.
متن کاملEthyl 3-[1-(2-hydroxyphenyl)ethylidene]carbazate
The title compound, C(11)H(14)N(2)O(3), was prepared by the reaction of ethyl carbazate and 1-(2-hydroxy-phen-yl)ethanone. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds, forming centrosymmetric dimers. An intra-molecular O-H⋯N inter-action also occurs.
متن کامل3-(2-Ethyl-2-phenylhydrazin-1-ylidene)indolin-2-one
In the title compound, C16H15N3O, the dihedral angle between the indole ring system (r.m.s. deviation = 0.020 Å) and the phenyl ring is 14.49 (9)°. The mol-ecular conformation is supported by an intra-molecular C-H⋯O inter-action, which closes an S(7) ring. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R2(2)(8) loops.
متن کامل5-Ethyl-3-(3-fluorophenylsulfonyl)-2-methyl-1-benzofuran
In the title compound, C(17)H(15)FO(3)S, the fluoro-phenyl ring makes a dihedral angle of 76.11 (5)° with the mean plane of the benzofuran fragment. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
