Density and Speed of sound have been measured for pure components such furan, (DMF) 2-5-dimethylfuran, MDEA (n-methyldiethanolamine), DEG (diethylene glycol), TEG (triethylene DMA (dimethylacetamide) using Anton Paar (DSA-5000) vibrating U-tube densitometer in a temperature range 278.15 to 343.15 K ambient pressure (100 kPa). density speed furan + MDEA, DEG, TEG, 303.15 whereas DMF DMA, the is ...

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...

chitosan/polyethersulfone (cs/pes) composite membrane was prepared from casting chitosan solution on polyethersulfone substrate membrane. the substrate membrane was prepared by phase inversion technique using polyethersulfone (pes) and dimethylacetamide (dmac) as solvent with and without the addition of polyvinylpyrrolidone (pvp) as pore-forming agent. the effects of the composition of the c...

BACKGROUND/AIMS A deficit of various hormones during the process of aging and/or a heightened inflammatory state may be causally linked to the development of frailty. Phytoestrogens as weak estrogens, antioxidants, and anti-inflammatory agents may counteract this process. METHODS In a cross-sectional study including two cycles of the National Health and Nutrition Examination Survey (NHANES, i...

Dimethylformamide dimethylacetal (DMFDMA) is widely used as a source of electrophilic one-carbon units at the formate oxidation level; however, electrophilic methylation with this reagent is previously unreported. Reaction of anthranilamide with DMFDMA at 150 °C for short periods gives mainly quinazolin-4-one. However, prolonged reaction with dimethylformamide di(primary-alkyl)acetals leads to ...

This study deals with the generation and characterization of various solid-state forms of celecoxib, a selective cyclooxygenase-2 (COX-2) inhibitor. The drug was subjected to polymorphic screen using different solvents to explore the possibility of existence of different solid forms. N,N-Dimethyl acetamide (DMA) and N,N-dimethyl formamide (DMF) yielded solvates in 1:1 stoichiometric ratio. Quen...

Dawley male and female rats (3 , 5 , 6). As NFTA4 (Chart 1) differs from N-[4-5-nitro-2-furyl)-2-thiazolylj formamide only in that the acetyl group replaces the formyl group; and because NFTA is currently being used as an antibiotic in the therapy of human infectious disease, it seemed imperative that NFTA be studied for chronic toxicity and possible carcinogenicity.
