The Ultrasonic velocity (U) and density (ρ) for binary mixture of dimethyl acetamide (DAMC) and acetone at frequencies 2MHZ, 4MHz, 6MHZ ,and 8MHZ ..Ashok Kumar DashRita Paikaray
Density functional theory was applied to the calculation ofmolecular structures of N-methyl formamide (NMF), N, N-dimethylformamide (DMF), and N,N- dimethyl acetamide (DMA). DFT calculationson NMF, DMF, and DMA were performed using a combination of the localfunctional of Vosko, Wilk, and ...
BIS (P-DIMETHYLSILYL) PHENYL ETHER (CAS 13315-17-8, C16H22OSi2), is a colorless liquid, widely used in organic synthesis, with excellent thermal stability and resistance to moisture, playing a crucial role in the production of specialty chemicals and pharmaceuticals....

Pellets were solubilized in methoxyamine HCl, and derivatized with 70 μL N-(tert-butyldimethylsilyl)-N-methyltrifluoroacetamide (MTBSTFA) at 70°C for 1 hour. Next, 1 μL was injected into an Agilent 5975C GC/MS according to published protocols (Gravel et al., 2014). Mass isotopomer ...
Scale-up to industrial production level of a fermentation process occurs after optimization at small scale, a critical transition for successful technology transfer and commercialization of a product of interest. At the large scale a number of important
Samples for GC/MS analysis were dried under vacuum desiccation for a minimum of 18 hrs prior to being derivatized under nitrogen using bistrimethyl-silyl-trifluoroacetamide. The GC column was 5% phenyl dimethyl silicone and the temperature ramp was from 60°C to 340°C over a 17- minute ...
In terms of theo-substituted pharmacophores, the sequence of fungicidal activity againstRhizoctonia solaniwas methoxyiminoacetate moiety (5a-5h) > methoxyiminoacetamide moiety (6a-6h) > methoxyacrylate moiety (3a-3e) in general, irrespective of difference in substituent R on the terminal phe...
By using a lower spinning speed it is possible to increase the residence time in the dry spinning chimney and to reduce the residual level of, for example, dimethyl-acetamide (DMAC) solvent. However, this is at the expense of the spinning efficiency. Nor is it possible to raise the tempera...
Examples include PQ-1, PQ-42 (poly[oxyethylene(dimethyliminio)ethylene (dimethyliminio)ethylene dichloride]), and the like. Cationic water soluble polymeric tetraalkyl phosphonium salts may also be used in place of the ammonium salts. Non-polymeric cationic organic components having two or more ...
