There are two independent mol-ecules and one toluene solvent mol-ecule in the asymmetric unit of the title compound, C(25)H(12)Br(4)·0.5C(7)H(8). The dihedral angles between the fluorene ring systems are 85.30 (6) and 84.95 (6)° in the two mol-ecules. The disortions in angles from the ideal sp(3)-hybridization geometry around the tetra-hedral C atoms are due to the strain imposed by the central...

The title dimeric zirconium complex, [Zr(2)(C(20)H(24))(2)S(2)]·C(7)H(8), was obtained from the reaction of (ebthi)Zr(η(2)-Me(3)Si-C(2)-SiMe(3)) [ebthi is rac-1,2-bis-(η(5)-4,5,6,7-tetra-hydro-inden-1-yl)ethane] and S=C=N-ada (ada = adamantan-1-yl) along with the formation of the isonitrile C N-ada. Each Zr(IV) atom is coordinated by the sterically hindered ebthi ligand and two μ-sulfide ligand...

Antiallergic activity of Aristolochia bracteolata was evaluated by using compound 48/80 induced anaphylaxis, dermatitis rhinitis and pruritus, as a preclinical model for acute phase of hypersensitivity reactions. The late phase hypersensitivity was evidenced by considering toluidine diisocyanate induced volume of bronchoalveolar fluid secretion and its inhibition. The possible antiallergic mech...

Applications for lignin and lignosulfonates are limited today due to the undefined structure and varying properties of the substance. However, lignin, as the second most abundant bio-resource besides cellulose and the bio-resource with one of the highest natural carbon contents, has the potential to act as a precursor for carbon materials. In this study we have applied a Kraft lignin and a sodi...

A series of 2,6-disubstituted pyridine derivatives were prepared from 2,6-diacetylpyridine or 2,6dicarbonyl pyridine dichloride as starting materials. Reaction of 2,6-diacetylpyridine 1 with hydroxylamine hydrochloride or different aromatic aldehydes afforded the corresponding 2,6-diacetylpyridine dioxime and 2,6-bis-[β -(2-thienyl)acryloyl]pyridine derivatives 2 and 3, respectively. Additional...

Dinitrotoluene (DNT) is generally produced as a mixture called technical-grade DNT (Tg-DNT), which contains approximately 76.5% 2,4-DNT and 18.8% 2,6-DNT (with the remainder consisting of other isomers and minor contaminants such as TNT and mononitrotoluenes). It is primarily used as a chemical intermediate for the production of toluene diisocyanate. DNT is also used in the production of 2,4,6-...

This chapter presents and discusses the current state of the art regarding adhesion mechanisms in characterizing durable adhesive bonds for wood composites. Particular emphasis is placed on phenol-formaldehyde (PF) and polymeric methylene diphenyl diisocyanate (pMDI) adhesives. An overview of current adhesion mechanisms is presented with an emphasis on categorizing adhesion mechanisms relative ...
