Sub-Atmospheric Distillation for Water (1) + Dimethyl Amino Ethyl Azide (2) Mixture
Dimethyl amino ethyl azide (DMAZ) is a good replacement for hydrazine group in space programs. This chemical was purified from water (1) + DMAZ (2) mixture in sub-atmospheric distillation column due to thermal sensitivity of DMAZ. For designing of the column, it is necessary to have vapor-liquid equilibrium data. In this article, T-x,y and y-x diagrams were obtain...
متن کاملEthyl 2-(3-chloro-2-pyridyl)-5-oxopyrazolidine-3-carboxylate
In the mol-ecule of the title compound, C(11)H(12)ClN(3)O(3), the five membered ring adopts an envelope conformation. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
متن کاملTris(3-amino-5,6-dimethyl-1,2,4-triazine-κN 2)silver(I) trifluromethanesulfonate–3-amino-5,6-dimethyl-1,2,4-triazine (1/1)
The asymmetric unit of the title compound, [Ag(C(5)H(8)N(4))(3)](CF(3)O(3)S)·C(5)H(8)N(4), contains two cations, two anions and two uncoordinated 3-amino-5,6-dimethyl-1,2,4-triazine (admt) ligands. It was prepared from the reaction of silver trifluoro-methane-sulfonate and admt in a 2:3 molar ratio. Both silver(I) ions are bonded to three admt mol-ecules via their 2-position triazine N atoms in...
متن کاملEthyl 3-amino-5-bromo-1-benzofuran-2-carboxylate
The title compound, C11H10BrNO3, is close to planar with the benzo-furan unit and the ester group subtending a dihedral angle of 5.25 (2)°. The mol-ecular structure features an intra-molecular N-H⋯O inter-action. In the crystal, N-H⋯O hydrogen bonds involving carboxyl O-atom acceptors generate a chain extending along [201].
متن کاملEthyl 6-r-(2-chlorophenyl)-2-oxo-4-phenylcyclohex-3-ene-1-t-carboxylate
In the title mol-ecule, C(21)H(19)ClO(3), the cyclo-hexene ring adopts an envelope conformation, with all substituents equatorial. The plane through its five coplanar atoms makes dihedral angles of 12.75 (14) and 74.16 (8)° with the phenyl and benzene rings, respectively. The dihedral angle between the latter two rings is 81.73 (12)°. Inter-molecular C-H⋯O hydrogen bonds and intra-molecular C-H...
