Spectrophotometric Determination of Uranium Using 2-(2-Thiazolylazo)-p-Cresol (TAC) in the Presence of Surfactants
No presente trabalho apresenta-se um método seletivo e sensível para rápida determinação de urânio usando o 2-(2-Tiazolilazo)-p-Cresol (TAC). O TAC reage com o urânio(VI) em pH 6,5 formando um complexo estável por pelo menos 3 h. Brometo de N-cetil-N,N,N-trimetil amônio (CTAB) e triton X-100 foram usados para aumento da sensibilidade e solubilidade do sistema respectivamente. O método permite a...
متن کاملDesign and Synthesis of 2-Methyl and 2-Methyl-4-Nitro Imidazole Derivatives as Antifungal Agents
Two series (a and b) of N- substituted heteroaromatic compounds related to clotrimazole were synthesized. Imidazole ring of the clotrimazole was replaced by 2-methylimidazole in series a, and by 2-methyl-4-nitroimidazole in series b. O-cholortrityl moiety of clotrimazole was also replaced by trityl, mono or dimethoxy trityl. Chemical structures...
متن کامل2-({[4-(1,3-Benzothiazol-2-yl)phenyl]amino}methyl)phenol
In the title compound, C(20)H(16)N(2)OS, the aniline substituent essentially coplanar with the benzothia-zole moiety (with an r.m.s. deviation of all fitted non-H atoms of 0.0612 Å). The phenol group is almost perpendic-ular to the benzothia-zolylaniline group, with an inter-planar angle of 88.36 (2)°. In the crystal, mol-ecules aggregate as centrosymmetric dimers by pairs of O-H⋯N hydrogen bon...
متن کاملNuclear Radiations Induced Change in Thermal and Structural Properties of 2-}[4-(2-HydroxyBenzylideneamino) Phenylimino] Methyl{ Phenol (PAM) Schiff Base
The variation of thermal and structural properties of 2-{[4-(2-hydroxybenzylideneamino) phenylimino]methyl}phenol (PAM)Schiff base were studied using differential scanning calorimetry (DSC) and powder X-ray diffraction techniques before and after fast neutron (1.050 and 1.740kGy), beta (11.01Gy) and gamma (453.0Gy) irradiations. Under fast neutron irradiation, the melting and decomposition enth...
متن کامل4-Bromo-2-[5-methyl-2-(morpholin-4-yl)-1,3-thiazol-4-yl]phenol
In the title compound, C14H15BrN2O2S, synthesized by the reaction of the corresponding phenacyl thio-cyanate with morpholine, the dihedral angle between the 1,3-thia-zole ring and the phenolic substituent ring is 23.46 (10)° as a result of the steric influence of the ortho-methyl group on the thia-zole ring. A strong intra-molecular phenolic O-H⋯N hydrogen bond is present in the mol-ecule. In t...
