These studies are based on the solvent System N,N-dimethylacetamide (DMAc)/LiCl which is used, e. g., for the determination of the molecular weight distribution of cellulosic Substrates by size exclusion chromatography (SEC).. Results are presented on static and dynamic laser-light-stattering experiments carried out in the concentration range employed in SEC and discussed in terms of the soluti...

This paper presents the results of a study random copolyethersulfone sulfides based on 4,4-dichlorodiphenylsulfone, 1,1-dichloro-2,2-di(4-hydroxyphenyl)ethylene, and sodium sulfide. The synthesis with different ratios polyethersulfone polyphenylenesulfone sulfide units was carried out by high-temperature polycondensation reaction nucleophilic substitution in N,N-dimethylacetamide medium using p...

The ultrasonic velocity, density and viscosity at 318K have been measured in the binary systems of Methyl methacrylate + Toluene and Methyl methacrylate + Dimethylacetamide. In this work an attempt has been made for the first time to investigate the behavior of binary solutions of Methylmethacrylate(MMA) in Toluene and Dimethylacetamide(DMAC) with regard to acoustical parameters such as adiabat...

Despite their prevalence in organic synthesis, the application of boronic acids (BAs) as alkyl radical precursors visible-light-assisted photocatalyzed reactions has been limited by high oxidation potential. This study demonstrates prominent ability amide solvents, namely, N,N-dimethylacetamide, to participate hydrogen-bonding interactions with BAs, thus enabling modulation potential toward gen...

Murine-virus-infected erythroleukemia cells cultured in a medium with dimethylsulfoxide or N,N-dimethylformamide are induced to differentiate to erythroid cells. A number of highly polar compounds have a similar effect in inducing erythroid differentiation of the virus-infected cells, as assayed by the appearance of hemoglobin. These compounds are 1-methyl-1-2-piperidone, N,N-dimethylacetamide,...

Two new cadmium(II) luminescent coordination polymers (CPs), [Cd(L)Cl2]·3DMF (1) and [Cd(L)(DMA)(H2O](ClO4)2·5DMA (2) (L = 1,1,2,2-tetrakis(4-(1H-imidazol-1-yl)phenyl)ethene, DMF N,N-dimethylformamide, DMA N,N-dimethylacetamide), were synthesized under solvothermal conditions. Crystallographic analyses reveal that 1 2 have different two-dimensional (2 D) network structures. Both show mechanochr...
