The conformation of the N-H bond in the structure of the title compound, C(10)H(12)ClNO, is syn to the ortho methyl group, similar to that observed with respect to the meta methyl group in 2-chloro-N-(3-methyl-phen-yl)acetamide and the ortho-chloro group in 2-chloro-N-(2-chloro-phen-yl)acetamide. The geometric parameters are similar to those of other acetanilides. The mol-ecules are linked into...

The title compound, [Tb(C(9)H(3)O(6))(C(4)H(9)NO)(2)], shows a rare-earth three-dimensional metal-organic framework structure. In this complex of an eight-coordinated Tb(3+) ion, the asymmetric unit contains one benzene-1,3,5-tricarb-oxy-lic ligand and two coordinated dimethyl-acetamide mol-ecules. Each Tb(3+) ion is coordinated by six O atoms from four carboxyl-ate groups of the benzene-1,3,5-...

The sulfate-reducing culture N47 can utilize naphthalene or 2-methylnaphthalene as the sole carbon source and electron donor. Here we show that the initial reaction in the naphthalene degradation pathway is a methylation to 2-methylnaphthalene which then undergoes the subsequent oxidation to the central metabolite 2-naphthoic acid, ring reduction and cleavage. Specific metabolites occurring exc...

Given that the degradation of aromatic pollutants in anaerobic environments such as sediment is generally very slow, aeration could be an efficient bioremediation option. Using stable isotope probing (SIP) coupled with pyrosequencing analysis of 16S rRNA genes, we identified naphthalene-utilizing populations in aerated polyaromatic hydrocarbon (PAH)-polluted sediment. The results showed that na...

UNLABELLED Naphthalene is a ubiquitous pollutant, and very high concentrations are sometimes encountered indoors when this chemical is used as a pest repellent or deodorant. This study describes the distribution and sources of vapor-phase naphthalene concentrations in four communities in southeast Michigan, USA. Outdoors, naphthalene was measured in the communities and at a near-road site. Indo...

PURPOSE Recent studies have indicated that certain aldose reductase inhibitors prevent the formation of cataracts in naphthalene-fed rats. The study was designed to investigate whether aldose reductase itself is involved in the metabolism of naphthalene in the lens and the mechanism of this cataract formation. METHODS Aldose reductase was purified from whole rat lens using a series of chromat...

Genetically constructed microbial biosensors for measuring organic pollutants are mostly applied in aqueous samples. Unfortunately, the detection limit of most biosensors is insufficient to detect pollutants at low but environmentally relevant concentrations. However, organic pollutants with low levels of water solubility often have significant gas-water partitioning coefficients, which in prin...

Understanding and eliminating degradation of the electrolyte solution is arguably major challenge in development high energy density lithium–air batteries. The use acetonitrile provides cycle stability comparable to current state-of-the-art glyme ethers and, while solvent has been extensively studied, no mechanism for proposed. Through application situ pressure measurements ex characterization ...

In the title compound, C(13)H(18)N(2)O(5)S, the benzene ring and the acetamide group are almost coplanar [dihedral angle = 5.6 (3)°], and the amine group projects almost vertically from this plane [C-C-S-N = -84.5 (7)°]. A short intra-molecular C-H⋯O contact occurs. In the crystal, O-H⋯O, N-H⋯O and N-H⋯(O,O) hydrogen bonds lead to a three-dimensional network. One of the methyl groups of the iso...

The title acetamide compound, C(8)H(9)BrN(2)O, crystallizes with three crystallographically independent mol-ecules (A, B and C) in the asymmetric unit. In mol-ecule A, the mean plane through the acetamide unit is inclined at a dihedral angle of 4.40 (11)° with respect to the pyridine ring [10.31 (12) and 2.27 (11)°, respectively, for mol-ecules B and C]. In the crystal structure, mol-ecules are...
