Bis(3,5-dimethoxyphenyl)phosphinic acid
In the crystal structure of the title compound, C(16)H(19)O(6)P, inter-molecular O-H⋯O inter-actions link the mol-ecules into chains parallel to the b axis. These chains are linked by C-H⋯π and π-π inter-actions [centroid-centroid distance = 3.7307 (29) Å] into a three-dimensional network. The dihedral angle between the benzene rings is 73.5 (1)°. The C and O atoms of all four methoxy groups li...
متن کاملMedium Density Fiberboard (mdf) Manufacturing
In this study wheat straw was taken from Ankara province. In order to produce dry process MDF, urea formaldehyde resin was used at the ratio of 8 %, 10 % and 12 %, 1 % ammonium chloride was used as hardening agent on the basis of dry fiber weight. On the other hand, 5, 6 and 7 min. pressing times were applied. Alcohol benzene, cold water, hot water and 1 % NaOH solubility of wheat straw were 5....
متن کاملBis(pyrrolidin-1-yl)phosphinic (2,4-difluorobenzoyl)amide
The P atom in the title mol-ecule, C(15)H(20)F(2)N(3)O(2)P, is in a distorted tetra-hedral P(O)(N)(N)(2) environment. The phosphoryl group and the NH unit adopt a syn orientation with respect to each other. An F atom at position 2 and an H atom at position 6 are found to occupy similar sites in a 0.70:0.30 ratio and were refined with fixed occupancies. The pyrrolidin-1-yl rings are disordered o...
متن کاملA novel tridentate bis(phosphinic acid)phosphine oxide based europium(III)-selective Nafion membrane luminescent sensor.
A new europium(III) membrane luminescent sensor based on a new tridentate bis(phosphinic acid)phosphine oxide (3) system has been developed. The synthesis of this new ligand is described and its full characterization by NMR, IR and elemental analyses is provided. The luminescent complex formed between europium(III) chloride and ligand 3 was evaluated in solution, observing that its spectroscopi...
متن کاملA Density Functional Theory Study of Structure of Phosphonic Acid
The molecular structure of the stable conformation of phosphonic acid in gas phase has beencomputed by employing complete geometry optimization in Density Functional Theory(DFT) methods. The methods used for calculations are B3LYP, BP86 and B3PW91 that havebeen studied in two series of basis sets: D95** and 6-31+G(d,p) for hydrogen and oxygenatoms; LANL2DZ for phosphorus. Bond lengths and angle...
