The structure of the copolymers was determined by IR and their conductivity by impedance spetroscopy. Closer insight into the kinetics of copolymerization of OMA with 3-aminobenzenesulfonic acid (MA), 2-aminobenzenesulfonic acid (OA), 3-aminobenzoic acid (ABA) or 2-aminobenzoic acid (AA) was...
Aniline is an organic compound with the formula C6H5NH2. Consisting of a phenyl group attached to an amino group, aniline is the simplest aromatic amine. It is an industrially significant commodity chemical, as well as a versatile starting
energy storage, sensors, and medical diagnosis. We report novel, tunable, and uniform hollow microspheres of conjugated poly(aniline-co-3-amino-9-ethyl-carbazole) (PAC) copolymer synthesized by a template-free method, namely a simple chemical...

(a) Structures of 1–4 [1, N1-(pyridin-2-ylmethyl)benzene- 1,4-diamine; 2, 3,5-dimethoxy-N-(pyridin-2-ylmethyl)aniline; 3, N1,N1-dimethyl-N4-(quinolin-2-ylmethyl)benzene-1,4-diamine; 4, N1-((1H-pyrrol-2- yl)methyl)-N4,N4-dimethylbenzene-1,4-diamine] and their targets (...
Nitration of aniline « on: October 31, 2017, 11:52:03 AM » I found the product ratio of para to ortho to meta ratio in the nitration of aniline to be 51% : 2% : 47%. As per explanation given by textbooks...Even though in acidic medium aniline is converted to anilinium ion...
The reaction of bis(4-cyclohexylbutyrato)cobalt(II), Co(C10H17O2)2, with the lithium salt of N,N′-diphenyibenzamidine in tetrahydrofuran results in the formation of tetrakis(μ-N,N′-diphenylbenzamidinato)dicobalt(II), Co2(dpb)4 (1). The crystal and molecular structure of 1 has bee...
A method for the selective deuteration of anilines, indoles, phenols and heterocyclic compounds, including natural products and other bioactive molecules, has been developed. The nanostructured iron catalyst that underpins this process is prepared by combining cellulose with iron salts and has been used...
There is no unified discussion of the structure and role of chemical explanations nor focused consideration of the nature of laboratory practice, including the methodologies of chemical synthesis and analysis and the integration of modern instrumentation in the twentieth century. We address each of ...
