(1-Naphthylmethyl)ammonium chloride
The reaction of 1-naphthyl-methyl-amine and hydro-chloric acid in a 1:1 molar ratio resulted in the formation of the 1:1 proton-transfer compound, C(11)H(12)N(+)·Cl(-). In the crystal, the ions are linked by N-H⋯Cl hydrogen bonds into a sheet pattern in the ab plane such that each Cl(-) ion is bonded to three NH groups from the naphthylmethylammonium ion.
متن کامل(Methyldiphenylphosphoranylidene)ammonium chloride
The title compound, C(13)H(15)NP(+)·Cl(-), was obtained by hydrolysis of the N-trimethysilyl derivative of methydiphenyl-imino-phosphine. The dihedral angle between the phenyl rings in the cation is 61.5 (3)°. In the crystal structure, inter-molecular N-H⋯Cl hydrogen bonds links the two components, forming a centrosymmetric 2 + 2 aggregate.
متن کاملCorrection of thiazide hyperuricemia by potassium chloride and ammonium chloride.
Large doses of KCI lowered serum uric acid while producing mild, apparently unrelated, uricosuria in four chlorothiazide-treated subjects. In two control subjects KCI also caused mild uricosuria, but had a negligible effect on serum uric acid concentration. Ammonium chloride decreased serum urate in all six subjects, while urinary uric acid excretion remained essentially unchanged. It is sugges...
متن کاملAmmonium Chloride and Ammonium Sulfate in Cattle Feedlot Finishing Rations
T WO levels of ammonium chloride or of ammonium sulfate were added to the rations of commercial feeder cattle. The rations were made isonitrogenous, essentially isocaloric and to contain the same level of calcium, phosphorus and salt. Total gains were essentially the same for all lots, varying only 15.6 lb (7.1 kg) over a 112 day feeding period. Feed conversion was increased only on the ration ...
متن کاملThe transitional plasticity of ammonium chloride
2014 From a phenomenological theory of domain kinetics in a coherent two-phase field it is inferred that the creep rate at the start of macroplastic deformation goes to zero, as the temperature approaches the singular point of the thermal relaxation time. It is pointed out that the erosion of the domains decorating the edge dislocations can be followed through the intensity of the light scatter...
