Catalytic Oxidation of 4-Methylpyridine on Modified Vanadium Oxide Catalysts
The reaction of gas-phase oxidation of 4-methylpyridine on individual V2O5, binary and ternary vanadium-oxide catalysts was studied. These catalysts were modified by additives of SnO2 and TiO2. It was found that modifying V2O5 leads to increase the activity of binary contacts. Upon transition from binary V2O5<...
متن کاملPyridine and 3-methylpyridine solvates of the triple sulfa drug constitutent sulfamethazine.
Sulfonamides display a wide variety of pharmacological activities. Sulfamethazine [abbreviated as SMZ; systematic name 4-amino-N-(4,6-dimethylpyrimidin-2-yl)benzenesulfonamide], one of the constitutents of the triple sulfa drugs, has wide clinical use. Pharmaceutical solvates are crystalline solids of active pharmaceutical ingredients (APIs) incorporating one or more solvent molecules in the cr...
متن کاملDegradation of 3-methylpyridine and 3-ethylpyridine by Gordonia nitida LE31.
Cells of Gordonia nitida LE31 grown on 3-methylpyridine degraded 3-ethylpyridine without a lag time and vice versa. Cyclic intermediates were not detected, but formic acid was identified as a metabolite. Degradation of levulinic acid was induced in cells grown on 3-methylpyridine and 3-ethylpyridine. Levulinic aldehyde dehydrogenase and formamidase activities were higher in cells grown on 3-met...
متن کاملcatena-Poly[sodium [[tris(3-methylpyridine-2-carboxylato)europate(III)]-μ-3-methylpyridine-2-carboxylato] trihydrate]
In the title structure, {Na[Eu(C(7)H(6)NO(2))(4)]·3H(2)O}(n), the Eu(III) atom is nine-coordin-ated within a slightly distorted tricapped trigonal-prismatic coordination geometry defined by five carboxyl-ate-O atoms and four pyridine-N atoms. One of the carboxyl-ate ligands bridges the Eu cations, forming a one-dimensional coordination polymer along the b axis. The Eu-O bond distances lie withi...
متن کاملAn Expeditious Synthesis of New 5-acetyl-4-(4’-alkyloxyphenyl)- 3-cyano-6-methylpyridine-2(1H)-thiones and Derivatives
A convergent synthesis of 5-acetyl-4-(4'-alkyloxyphenyl)-3-cyano-6-methylpyridine-2(1H)-thiones and their derivatives S-alkylthiopyridines was described. The main steps towards the formation of the title compounds involve the reactions of 4-alkyloxybenzaldehydes with 2-cyanothioacetamide to afford 2-cyano-3(4'-alkyloxyphenyl)prop-2-enethioamides which then reacted with acetylacetone prior to th...
