Thermal Decompositions of Some Divalent Transition-Metal Complexes of Triethanolamine
(John Wiley & Sons Ltd, 1995)
The thermal behaviours of the Ti(II), Mn(II), Fe(II), Ni(II), (II), Zn(II) and Zn(II) complexes of triethanolamine were studied by means of thermogravimetry, differential thermogravimetry, differential thermal analysis ...
Corrosion Inhibition of Steel in Concrete By Carboxylic-Acids
(Pergamon-Elsevier Science Ltd, 1993)
Water soluble carboxylic acids have been used as corrosion inhibitors. They remain largely soluble after curing in cement for up to 90d. Corrosion current measurements are presented showing malonic acid, a dicarboxylic ...
Quantitative-Determination of Triethanolamine in Cements
(Pergamon-Elsevier Science Ltd, 1993)
A new analysis method for the quantitative determination of triethanolamine (TEA) in the aqueous phase of cements was developed. TEA was converted into the TEA-Fe3+ complex by treating it with 1M NaOH and 10% Fe3+ solutions. ...
Thermal-Behavior and Kinetic-Analysis of the Thermogravimetric Data of Double Ammonium-Sulfate Hexahydrate Salts of Mn(Ii), Fe(Ii), Co(Ii), Ni(Ii) and Cu(Ii)
(Elsevier Science Bv, 1994)
The thermal behaviour of double ammonium sulphate hexahydrates of Mn(II), Fe(II), Co(II), Ni(II) and Cu(II) was studied in air using TG and DTA techniques. X-ray powder diffractometry was used to identify the solid ...
Molecular structure of 2'-hydroxy-3'-methoxy-5'-allyl-4-methylazobenzene
(Scientific Technical Research Council Turkey, 1996)
2'-hydroxy-3'-methoxy-5'-allyl-4-methylazobenzene was synthesized in two steps: 4-methylbenzenediazonium chloride was prepared by the reaction of 4- methylaniline, HCL and NaNO2, and was then reacted with eugenol to give ...
Crystal structure of tris(2-hydroxyethyl)ammonium bromide
(Scientific Technical Research Council Turkey, 1996)
The crystal structure of tris(2-hydroxyethyl)ammonium bromide, [HN(CH2CH2OH)(3)]BT, was determined as rhombohedral by single crystal X-ray diffractometer. The final R value was found to be 0.032 for 576 observed reflections. ...
Preparation and Spectroscopic Examination of Some Inclusion Complexes of Ferrocene and Its Derivatives With Beta-Cyclodextrin
(Scientific Technical Research Council Turkey, 1995)
Inclusion complexes of ferrocene and its derivatives with beta- cyclodextrin(beta-CD) were prepared in high yields. beta-CD formed 1:1 stoichiometric compounds with ferrocene and its mono-and disubstituted derivatives while ...
The Degradation of Cement Superplasticizers in A High Alkaline-Solution
(Pergamon-Elsevier Science Ltd, 1993)
Commercial cement superplasticizers(SMF and SNF) were treated with 1M KOH solutions for up to 2.0 days. The chemical changes were characterized by chemical analysis, IR spectroscopy and thermal analysis techniques. After ...
Distribution of uranium in the production of triple superphosphate (TSP) fertilizer and phosphoric acid
(Kluwer Academic Publ, 1996)
In this study the distribution of uranium, which is one of the radioactive elements present in phosphate fertilizers was investigated in different steps of the triple superphosphate (TSP) production process. The uranium ...
Thermal-Decomposition of Beta-Cyclodextrin Inclusion Complexes of Ferrocene and Their Derivatives
(Elsevier Science Bv, 1995)
The thermal decomposition of the solid inclusion complexes of ferrocene and its derivatives with beta-CD was studied by DTA, TG and DTG. The inclusion complexes contain crystallization water and the first decomposition ...
