Nuclear Magnetic Resonance Investigation of a Sodium Dibutyl Phosphate/Water Lyotropic Mesophase

2H and 31P NMR have shown that concentrated aqueous solutions of sodium dibutyl phosphate (NaDBP) give rise to a lamellar mesophase for NaDBP mole fractions varying from 0.1 to 0.2 in a temperature range T=285-340 K.By cooling the samples from the isotropic phase in a magnetic field the formation of a discotic DM II mesophase is observed.Different models of water reorientation are proposed to account for the 2H and 17O quadrupole splittings.Nuclear relaxation experiments show that, in this particular system, water molecules reorient preferentially about the direction of an oxygen lone pair orbital.

Visible light induced redox neutral fragmentation of 1,2-diol derivatives

A homogeneous, redox-neutral photo fragmentation of diol derivatives was developed. Under photo/hydrogen atom transfer (HAT) dual catalysis, diol derivatives such as lignin model compounds and diol monoesters undergo selective β C(sp3)-O bond cleavage to afford ketones, phenols and acids effectively.

Linear coordination polymers based on aluminum phosphates: Synthesis, crystal structure and morphology

Several aluminum tris(diorganophosphates) have been synthesized and characterized via elemental analysis, NMR, FT-IR and Raman spectroscopy, as well as powder XRD, and SEM. Single-crystal X-ray diffraction studies revealed that the aluminum tris(diethylphosphate) crystal structure comprises two crystallographically nonequivalent catena-Al[O2P(OEt)2]3 chains propagating along the c-axis. Their parallel orientation favors the formation of closely packed hexagonal domains. PXRD data suggest that other homologues have a similar structure, with the interchain distance closely corresponding to the dimensions of organic ligands. They are also susceptible to a reversible dissociation to ionic species under the effect of primary amines. This feature can be utilized for the synthesis of epoxy nanocomposites.The Royal Society of Chemistry.

Autocatalytic alkaline hydrolysis of tri-n-butyl phosphate

Although the alkaline hydrolysis of tri-n-butyl phosphate, TBP, in homogeneous aqueous solution shows normal second order kinetics, the hydrolysis of a solution with a hydrocarbon diluent by concentrated sodium hydroxide at 388 K shows an induction period followed by an autocatalytic reaction. The reaction starts with two liquid phases, and ends with three, the third phase consisting mainly of sodium di-n-butyl phosphate, NaDBP, together with hydrocarbon, TBP, BunOH, H2O and NaOH. The autocatalysis arises from the fact that the third phase dissolves appreciable concentrations of both TBP and NaOH, and serves to bring the reactants together, although the second order rate constant for reaction in the third phase is not much greater than it is in water. As hydrolysis proceeds the volume of the third phase increases while the other phases shrink, thus increasing the rate and resulting in autocatalysis.
