Crystal structures of three new N-halomethylated quaternary ammonium salts
In the crystals of the title N-halo-methyl-ated quaternary ammonium salts, C19H23IN(+)·I(-), (I) [systematic name: N-(4,4-di-phenyl-but-3-en-1-yl)-N-iodo-methyl-N,N-di-methyl-ammonium iodide], C20H25IN(+)·I(-), (II) [systematic name: N-(5,5-di-phenyl-pent-4-en-1-yl)-N-iodo-methyl-N,N-di-methyl-ammonium iodide], and C21H27IN(+)·I(-), (III) [systematic name: N-(6,6-di-phenyl-hex-5-en-1-yl)-N-iodo...
متن کاملQuantification of Ammonium Sulphate Nitrate (ASN) fertilizers
This paper shows a simple procedure for the quantification of industrial and laboratory samples of Ammonium Sulphate-Nitrate fertilizers (ASN) based on a Rietveld fit from X-ray powder diffraction profiles. The Rietveld fit is performed by means of the structural models of the double salts 2NH4NO3·(NH4)2SO4 and 3NH4NO3·(NH4)2SO4, previously reported by the authors. The proposed method demonstra...
متن کاملThe differential toxicity of ammonium salts.
The relationship between liver disease and ammonia toxicity has been known since the discovery of meat intoxication in Eck fistula dogs (1-4). The similarity between this syndrome and clinical hepatic coma stimulated the study of ammonia toxicity in humans. This proceeded from oral administration (5-10) to intravenous infusion (11, 12) and finally to the development of an "ammonia tolerance tes...
متن کاملMicrowave synthesis of quaternary ammonium salts.
The microwave synthesis of several quaternary ammonium salts is described. The synthesis provides comparable or better yields than published methods with reduced reaction times and in the absence of solvent.
