Nascent Ammonium Chloride in Pneumonia

(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.

(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.

Ammonium 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 ...

Phosphorescence Decay in Thallium-Doped Ammonium Chloride

The phosphorescence decay rates of thallium-doped ammonium chloride (NHUChTl) phosphors, prepared by crystallization from aqueous solution, have been studied at room temperature for near-ultraviolet emission. The effects of impurity concentration as well as thermal and/or mechanical treatment on the decay rates have been examined. Phosphorescence centres consisting of a Tl+ion and a nearby nega...
