Efficacy of alkyl dimethyl benzyl ammonium chloride on suppression of Physalospora vaccinii in laboratory assays.
Growth of Physalospora vaccinii on inoculated agar growth medium and cranberries treated with 0.1, 1, 10, 100, and 1,000 ppm of alkyl dimethyl benzyl ammonium chloride (ADBAC) was investigated in the laboratory. In vitro growth assays, the colony diameter, and mycelial dry weight of P. vaccinii was reduced at 1,000 ppm ADBAC. Mild or no reduction of fungal growth and mycelial dry weight was obs...
متن کامل(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 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 کاملInteractions of Quaternary Ammonium Compounds and Proteins
A simple met.hod of titration with a cationic detergent has been developed which permits rapid estimation of the concentration of urinary protein with a minimum of manipulations and time. The method depends on the formation of an insoluble anion-cation complex between quaternary ammonium ions, hereinafter referred to as the cationic detergent, and proteins, in the present instance mainly human ...
