Tetra-n-butylammonium bromide-water (1/38).
Tetra-n-butylammonium bromide forms the title semi-clathrate hydrate crystal, C16H36N+.Br-.38H2O, under atmospheric pressure. The cation and anion lie at sites with mm symmetry and seven water molecules lie at sites with m symmetry in space group Pmma. Br- anions construct a cage structure with the water molecules. Tetra-n-butylammonium cations are disordered and are located at the centre of fo...
متن کاملHydrogen Storage Capacity of Tetrahydrofuran and Tetra-N-Butylammonium Bromide Hydrates Under Favorable Thermodynamic Conditions
An experimental study was conducted to evaluate the feasibility of employing binary hydrates as a medium for H2 storage. Two reagents, tetrahydrofuran (THF) and tetra-n-butylammonium bromide (TBAB), which had been reported previously to have potential to form binary hydrates with H2 under favorable conditions (i.e., low pressures and high temperatures), were investigated using differential scan...
متن کاملSynthesis, Spectroscopic and X-Ray Structure Characterisation of Bis(tetramethylammonium) and Bis(tetra-n-butylammonium) Tetrathiomolybdates
The new tetraalkylammonium tetrathiomolybdates (Me4N)2[MoS4] (1) and (nBu4N)2[MoS4] (2) were prepared via a direct salt substitution using (NH4)2[MoS4] as starting material. Compound 1 crystallises in the non-centrosymmetric orthorhombic space group P212121 with a = 8.9233(4), b = 15.5210(9) and c = 37.255(3) Å. Compound 2 crystallises in the orthorhombic space group Fdd2 with a = 28.9142(18), ...
متن کامل1,4,5,8-Tetra-n-butylanthracene
The mol-ecule of the title compound, C(30)H(42), occupies a special position on an inversion center. The four butyl side chains have all-trans planar conformations, and the alkyl planes are nearly orthogonal to the anthracene plane [C-C-C-C torsion angles of 79.6 (2) and 78.2 (2)°]. The overall mol-ecule has a stair-like shape with the n-butyl groups at the 1 and 8 positions extending towards t...
متن کاملTETRA-N-BUTYLAMMONIUM FLUORIDE AS A NOVEL REAGENT FOR THE PREPARATION OF ACYCLO-NUCLEOSIDES. THE SYNTHESIS OF 9- [(2-HYDROXYETHOXY) METHYL] ADENINE, BITAMYCIN.
The synthesis of the title compound, bitamycin, by means of BU4NF is described. This new antiviral drug was found to be one of the most powerful and least toxic substances for antiviral therapy in man. The physical and chemical behavior as well as the antiviral activities and clinical properties of this compound were found to be significantly different from that reported by Schaeffer, et a...
