Bis(2-bromoethyl)ammonium bromide
The title salt, C(4)H(10)Br(2)N(+)·Br(-), crystallizes with four cations and four anions in the asymmetric unit. In the crystal, the bis-(2-bromo-eth-yl)ammonium cations and bromide anions are linked into chains by N-H⋯Br hydrogen bonds describing a binary C(2) (1)(4) motif along [010]. Each of these chains is formed by a unique cation and anion pair. The ammonium cations occur in the less pref...
متن کاملBiopolymer-surfactant Interactions: Binding Studies of Cetyltrimethyl Ammonium Bromide, Cetyl Pyridinium Bromide and Dodecyl Trimethyl Ammonium Bromide with Β-lactoglobulin
Binding studies of cationic detergents such as cetyltrimethyl ammonium bromide, Cetyl pyridinium bromide and dodecyl trimethyl ammonium bromide with β Lactoglobulin were carried out by equilibrium dialysis, ultraviolet difference and circular dichroism techniques at 25 C. Binding isotherms at pH 5·0, 7·0 and 9·0 show cooperative binding at all concentrations of detergents and the number of avai...
متن کاملAddition of Ethyl Alcohol to Triethyl Propargyl Ammonium Bromide
Rearrangement of propargyl amine salt, in the presence of a base was studied and it was concluded that this occurs through an allenic intermediate.
متن کاملSynthesis of Triethyl Propargyl Ammonium Bromide from Triethyl Amine With Propargyl Bromide
The reaction between trimethylamine with propargyl bromide was studied and the structure of triethyl propargyl ammonium bromide was illustrated by 1HNMR, IR, and Mass spectra.
متن کاملThe Germicidal Properties of Certain Quarternary Ammonium Salts With Special Reference to Cetyl-Trimethyl-Ammonium Bromide.
In 1916 Jacobs, Heidelberger, and coworkers at the Rockefeller Institute reported the discovery of a new class of synthetic compounds which possessed potent bactelicidal properties. By reacting hexamethylenetetramine with a large variety of substituted benzylor alkyl-halides, nujmerous quaternary salts of this base were obtained. It was observed that most of these salts had pronounced bacterici...
