Hydrogen bonding in phenol, aniline, and thiophenol has been investigated by n.m.r. spectroscopy and cryoscopy. While phenol shows evidence for the presence of monomer-dimmer-polymer equilibrium, thiophenol only indicates low monomer-dimer equilibrium. The extent of association in these three ...

structure, therefore, the inconsistence between calculation and experiment might be ignited from the strong intermolecular interaction between two neighbour PNTP molecules in solid state, considering the disulfide bonding36 between the two S-H or hydrogen-bonding37 between S-H and N-O groups, ...
The formation of intra- and intermolecular hydrogen bonds at different points of the pNIPAM phase transition has been investigated with infrared techniques in a number of reports [54,184,185]. ATR/FT-IR studies of pNIPAM in water have shown that intermolecular H-bonding between pNIPAM and water...
Price trend According to the Commodity Market Analysis System of SunSirs, the domestic hydrogen peroxide market fluctuated and rose in November, with an increase of SunSirs: Driven by Negative Factors, the Hydrogen Peroxide Market Was Weak and Declining ...
We describe a concept to achieve comb-like supermolecules by hydrogen bonding camphor sulphonic acid (CSA) doped polyaniline (PANI) to 4-Hexyl resorcinol (Hres). The supermolecules, in turn, self-organize to form cylindrical nanostructures with the distances of 35 between the cylinders. The self...
Initially, six CGS stations are simulated based on energy, exergy-economic and environmental analysis and then a comparative study is conducted between different stations. The results of numerical modeling show that the Mashhad-old station with 5315 kW and 31.062 ton/year has the highest amount of...
Of hydroxylation of derivatives of phenol and with the hydrogen peroxide, 1996, giving a high proportion of the precursor monohydroxyl in the meta and para characterizes in react the superacid medium, 1996 in a liquid, at temperatures ranging from about - 80c at 0c, on the compounds hydroxy...
1. Process for the hydroxylation of phenol and aniline derivatives with hydrogen peroxide, yielding a high proportion of meta-monohydroxylated derivatives, characterised in that hydrogen peroxide is reacted in a superacid liquid medium consisting of products which have activities of up to about -25 ...
Selective nickel-catalysed hydrogen exchange of phenol, aniline and pyridine derivativesThe mass spectra of a series of metal acetylacetonates have been rationalized in terms of ion reactions. There are many examples of a unit change in the valency of the metal atom of an ion with consequent ...
