Temperature dependence of the vapour tension of methyl-substituted phenol derivatives
Abstract
Notable among the coking products of coal are phenol and its derivatives, derived for the coal tar and water layer above ht tar. Given that phenol an its derivatives are mainly extracted from coal tar fractions by rectification, information on how the vapor tension of the individual components depends on the temperature is of great importance. For phenol and various substituted alkylphenols there are tabular data. In the pre-computer era these data were sufficient for the separation of phenol mixtures. However, the development and introduction of information technology in the coal industry and in the design process demands the mathematical description of the physicochemical processes of coking products. The temperature dependence of the saturated vapor pressure for organic compounds is commonly described by the Antoine equation.

Structure and spectroscopic and magnetic properties of rare earth metal(III) derivatives with the 2-formyl-4-methyl-6-(N-(2-pyridylethyl)formimidoyl)phenol ligand
The compounds [ML[sub 2](H[sub 2]O)[sub 4]](ClO[sub 4])[sub 3][center dot]4H[sub 2]O ((1)M), where M is a trivalent rare earth metal and L the bidentate liquid 2-formyl-4-methyl-6-(N-(2-pyridylethyl)formimidoyl)phenol, have been synthesized. Single crystals of [GdL[sub 2](H[sub 2]O)[sub 4]](ClO[sub 4])[sub 2]Cl[center dot]2.75H[sub 2]O have been obtained, and its crystal structure has been solved. This compound crystallizes in the monoclinic system, space group P2[sub 1]/c. The structure consists of [GdL[sub 2](H[sub 2]O)[sub 4]][sup 3+] cations, perchlorate and chloride anions and noncoordinated water molecules. The Gd atom is surrounded by eight oxygen atoms, four belonging to water molecules and the other four to the carbonyl andmore » -
Solvent Extraction of Technetium and Rhenium with Pyridine or Methyl-Substituted Pyridine Derivatives from Alkaline Media
