The analysis of the 27Al and 35Cl quadrupole coupling parameters of aluminum methyl chloride dimers were carried out on the basis of the density functional theory (DFT). The available experimental values of quarupole coupling constants were compared with their calculated ones. In this investigation, the correlations were made between calculated 27Al and 35Cl nuclear quadrupole coupling constant...

1-Pentene, respectively 1-hexene, were reacted with 13 homogeneous metallocene catalysts to give linear oligomerization products, predominantly dimers, with selectivities above 90%. The product distributions of the codimerization reactions of 1-pentene with 1-hexene reflected a binomial behaviour. Therefore, the ratio for dimers is 1:2:1 (C10:C11:C12) while the trimers (pentadecenes up to octad...

The title compounds, (N-methyl-N-phenyl-amino)(N-methyl-N-phenyl-car-bam-oyl)sulfide, C15H16N2OS, (I), and (N-methyl-N-phenyl-amino)-(N-methyl-N-phenyl-carbamo-yl)disulfane, C15H16N2OS2, (II), are stable derivatives of (chloro-carbon-yl)sulfenyl chloride and (chloro-carbon-yl)disulfanyl chloride, respectively. The torsion angle about the S-S bond in (II) is -92.62 (6)°, which is close to the th...

A computational study of dimers formed by aniline and one CH3X molecule, X being CN, Cl or F, was carried out to elucidate the main characteristics of the interacting systems. Two different structures were found for each of the dimers, depending on the relative location of the CH3X molecule with respect to the amino hydrogen atoms. The most stable minimum for both acetonitrile and methyl chlori...

The first betaine chloride tetrachloroidoferrate(III) double salt, (Hbet)2Cl[FeCl4] = (Hbet)Cl·(Hbet)[FeCl4], was obtained from a solution of betaine hydrochloride (HbetCl) and FeCl3·6 H2O in water. The crystal structure (orthorhombic, Pbcm, a = 6.2717(13), b = 12.841(3), c = 25.693(5) Å, Z = 4) is characterized by layers of tetrachloridoferrate(III) anions separated by chloride-bridged, H-bond...

introduction: the objective of this study was, wastewater quality investigation and removal efficiency of contaminants from the wastewater tile factory by using  coagulants includes ferric chloride, ferric sulfate and ferrous, aluminum sulfate and poly aluminum chloride in order to reuse it in the processing line. methods: this is an applied study. with regard to shiftwork schedules of the fact...

Hydrocarbostyril, which is a key intermediate in our new synthetic route to 6-nitroquipazine, can be prepared from 1-indanone oxime by Beckmann rearrangement. We have optimized the reaction by using a Lewis acid, aluminum chloride, in the yield of 91% instead of common acids such as polyphosphoric acid, and sulfuric acid used in conventional Beckmann rearrangement (20% in the literature, 10% in...
