A series of substituted pyridine dialcohols (2,6-bis(hydroxyalkyl)pyridines), 1-4, was used for the synthesis of various types of aluminum complexes. Aluminum methyl derivatives, 2-4a, were obtained by the reaction of AlMe3 with the corresponding ligand or transmetallation reactions of germylenes. Aluminum chloride complexes, 3-4b, were obtained by substitution of the Me group under the action ...

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 facto...

Phosphorus (P) runoff from fields fertilized with swine (Sus scrofa domesticus) manure may contribute to eutrophication. The objective of this study was to evaluate the effect of aluminum sulfate (alum) and aluminum chloride applications to swine manure on P runoff from small plots cropped to tall fescue (Festuca arundinacea Shreb.). There were six treatments in this study: (i) unfertilized con...

Alkylation of isobutane and 2-butene was carried out in a continuous unit using triethylamine hydrochloride (Et3NHCl)-aluminum chloride (AlCl3) ionic liquid (IL) as catalyst. The effects of impurities such as water, methanol, and diethyl ether on the stability of the catalytic properties and deactivation of the ionic liquid were studied in the continuous alkylation. In the Et3NHCl-2AlCl3 ionic ...

Equilibrium constants have been determined for the formation of 15 different zirconocene monomethyl monochloro complexes from the respective dichloride complexes and AI2 (CH3)6' The results indicate that the tendency of a particular zirconocene complex to exchange a chloride against a methyl ligand is a measure for the electron deficiency at its Zr center. The results indicate particularly low ...

Background: Aluminum, as an environmental pollutant, can exert oxidative stress on spermatogenesis and sperm morphology. Silymarin, an effective substance extracted from Silybum marianum, is a potent antioxidant which inhibits oxidative stress. Due to the damaging effects of aluminum on the male reproductive system as well as sperm and the role of silymarin, this study was performed to investig...

topical solutions containing aluminum chloride are known to be the first line of therapy for hyperhidrosis. palmar hyperhidrosis however, is less responsive to aluminum chloride therapy and successful treatment may require 6-8 h application of high concentrations up to 30% that commonly leads to skin irritation. the purpose of this study is to investigate the effect of 30 min iontophoretic appl...

introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...

background: the purpose of this work was to investigate the use of polyvinyl chloride (pvc) dyed with methyl red as a high dose radiation dosimetry. materials and methods: commercial pvc films from sabic made from resins pvc57s with thickness of 60 µm and methyl red with a molecular weight of 269.31 were used. irradiation was carried out using a 60co γ-ray generator with sources arranged in rec...
