A rapid and easy method for staining lipopolysaccharides with ethidium bromide is described. Lipopolysaccharides could be visualized by ethidium bromide with almost the same sensitivity as found with the silver-staining method in less than 30 min. The ethidium bromide-staining method was particularly suitable for staining lipopolysaccharides possessing acidic O-specific polysaccharides, which w...

Acute accidental methyl bromide poisoning was treated with haemodialysis. The treatment was successful in removing bromide from the blood but the patient persists with severe neuropsychiatric sequelae. To the best of our knowledge haemodialysis has not been used previously for the treatment of organic bromide poisoning.

The present work describes, the reaction between disodium salt of 1,3-dihydroxybenzene (in situ formation) and propargyl bromide was carried out in a solid-liquid biphasic phase transfer catalytic system at 50°C. Higher selectivity of the bis-derivative (1,3-bis(prop-2-ynyloxy)benzene) was obtained under solid-liquid PTC condion. The conversion of propargyl bromide of more than 99% was achieved...

In its earliest stages when treatment will produce the most favourable results, tuberculous meningitis may be difficult to diagnose clinically, since other infective non-bacterial conditions of the central nervous system may present a similar clinical picture at their onset. Since the bromide partition test and its use in the diagnosis of tuberculous meningitis were described (Taylor, Smith and...

In the title water-solvated salt, C(21)H(22)P(+)·Br(-)·H(2)O, the ionic components are linked by short C-H⋯Br contacts along the a-axis direction. The two half occupied water mol-ecules are connected to each other by strong O-H⋯O hydrogen bonds and they are also linked to the bromide anion by short O-H⋯Br contacts.

The title compound, C(7)H(10)NO(+)·Br(-), consists of almost planar 4-methoxy-anilinium cations, wherein the O atom lies 0.049 (3) Å out of the plane formed by the non-H atoms, and a Br(-) anion. Strong N-H⋯Br and N-H⋯(Br,Br) hydrogen bonding contributes to the stability of the crystal structure and links the cations and anions into a three-dimensional network.

In the crystal structure of the title hydrated bromide salt, C(20)H(20)P(+)·Br(-)·2H(2)O, O-H⋯Br and O-H⋯O hydrogen bonds as well as C-H⋯Br contacts connect the different components into a three-dimensional network. In the cation, the aromatic rings make dihedral angles of 55.24 (5), 76.16 (4) and 85.68 (4)°.

Vapor-liquid equilibrium and density measurements have been performed on 1.00-5.89 m tetrabutylammonium bromide (TBAB) in mixtures of 2-propanoland water. The VLE experiments were performed using a modified Othmer still a t ambient pressure. The effect of salt on the relative volatility of 2-propanol was evaluated at molalities of 1.00,1.79, and 5.89 over the full range of solvent composition. ...

The title compound, Cs(3)(Mo(2)O(7))Br, was synthesized by the reaction of CsNO(3), MoO(3) and 1-ethyl-3-methyl-imidazolium bromide. Its crystal structure is isotypic with K(3)(Mo(2)O(7))Br and contains (MoO(4))(2-) tetra-hedra which share an O atom to produce a [Mo(2)O(7)](2-) dimolybdate(VI) anion with a linear bridging angle and m2 symmetry. The anions are linked by Cs atoms (site symmetry m...
