Objective To identify the bacteria tolerating chlorinated anilines and to study the biodegradability of o-chloroaniline and its coexistent compounds. Methods Microbial community of complex bacteria was identified by plate culture observation techniques and Gram stain method. Bacterial growth inhibition test was used to determine the tolerance of complex bacteria to toxicant. Biodegradability of...

The title compound, C(15)H(14)N(2)O·0.67H(2)O, was prepared by the reaction of 4-acetoamine-benzaldehyde and aniline. The asymmetric unit contains six organic mol-ecules and four water mol-ecules. The dihedral angles between the aromatic ring planes in each organic mol-ecule vary from 42.4 (2) to 53.8 (2)°. In the crystal, an extensive network of inter-molecular N-H⋯O, O-H⋯N and O-H⋯O hydrogen ...

To develop efficient materials with enhanced adsorption and selectivity for genotoxic 2-aminopyridine in water, based on magnetic chitosan (CTs) and β-cyclodextrin (β-CD), the magnetic molecularly imprinted polymers (MMIPs) of Fe₃O₄-CTs@MIP and Fe₃O₄-MAH-β-CD@MIP were synthesized by a molecular imprinting technique using 2-aminopyridine as a template. The selective adsorption experiments for 2-...

It was only natural that the earlier investigators of the action of the oxidase, tyrosinase, on catechol should have assumed that the first stage in the reaction is the formation of o-quinone. More recently this view of the reaction has gained additional approval from the studies carried on by Pugh and Raper (1). One of the difficulties encountered in trying to determine the nature of the initi...

In the title mol-ecule, C(11)H(9)N(3)O(2)S, the thio-phene and benzene rings form a dihedral angle of 17.68 (9)°. The thio-phene S atom and the imine N atom are syn with respect to each other. In the crystal, N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules, forming a two-dimensional network parallel to (10-1).

The title compound, C(21)H(20)N(2)O(2), a Schiff base ligand, contains two independent mol-ecules (A and B) in the asymmetric unit, with similar conformations. In mol-ecule A, the central benzene ring forms dihedral angles of 30.79 (13) and 23.56 (13)°, respectively, with the amino and benzyl benzene rings, while in mol-ecule B these angles are 32.30 (13) and 13.13 (12)°. The mol-ecular structu...

The asymmetric unit of the title complex, (C(6)H(8)N)(2)[Cu(C(7)H(3)NO(4))(2)]·6H(2)O, contains half a copper(II)-dipicolinate complex located on a twofold rotation axis, one protonated aniline mol-ecule and three solvent water mol-ecules. The Cu(II) atom is coordinated by four O atoms and two N atoms from two dipicolinate ligands in a distorted octa-hedral environment. In the crystal, the comp...

A new proton transfer compound, formulated as (Hamp-6-pic)(Hpyzd) ∙H2O (1), has been synthesized from the reaction of pyrazine-2,3-dicarboxylic acid (H2pyzd)  and 2-amino-6-methyl pyridine (amp-6-pic), in 1:1 molar ratio. Extensive O−H×××O, N−H×××N and O−H×××O hydrogen bonds involving (Hamp-6-pic)+ cation, (Hpyzd)- anion and co-crystal water molecule٫ static electronic٫ and π…π stacking interac...

In the mol-ecular structure of the title compound, C(14)H(12)ClNO, the meta-Cl atom in the benzoyl ring is positioned anti to the C=O bond, while the ortho-methyl group in the aniline ring is positioned syn to the N-H bond. The two benzene rings are nearly coplanar [dihedral angle = 3.48 (5)°]. The crystal structure is stabilized by N-H⋯O hydrogen bonds, which link the mol-ecules into chains al...
