This finding has been rationalized in terms of different mechanisms. In 2-methyl-2-butanol a correlation between ultrasonic and dielectric relaxation processes has been observed. Additional contribution of ultrasonic absorption associated with isomeric internal rotational of the molecules has been assumed ...
data gap, the solubility of 1-naphthylamine in twelve pure solvents (acetone, acetonitrile, ethyl acetate, n-butyl acetate, cyclohexane, n-heptane, methanol, ethanol, n-propanol, iso-propanol, n-butanol, and iso-butanol) was experimentally investigated in the range from 273.15 K to 308.15 K....
In this study, mole-fraction solubility values of 4-CyBZA in fourteen common solvents including four low alcohols (methanol (MeOH), ethanol (EtOH), n-propanol (NPOH), n-butanol (NBOH)), four acetates (methyl acetate (MeAC), ethyl acetate (EtAC), n-propyl acetate (NPAC), n-butyl ...
cancer is second among the leading causes of mortality and accounts for millions of deaths every year preceded only by heart diseases1. A surge in cancer incidence has a negative impact
1. Vinylamine homopolymer of 3.6 to 9x106 average molecular weight consisting essentially of units of the formula: where R1 is hydrogen or a C2-C4 alkyl group. 2. The vinylamine homopolymer of claim 1, characterized in that its average molecular weight is 7x106. 3. The vinylamine homopo...
A crystal structure of the isolated Wzt-CBD bound to 3-methyl mannose provides atomistic insights into cap recognition by the CBD. A cryo-EM structure of full-length WzmWzt in a nucleotide-free conformation reveals a dramatic repositioning of the CBD dimer relative to Wzt’s NBD sub-domain, ...
Herein, water-soluble hollow cup-like macrocyclic molecules, sulfothiacalix[4]arene (STCAss) and sulfocalix[4]arene (SCA), are ionically bonded into the polyamide network to engineer the molecular-sieving properties of TFN membranes for organic solvent forward osmosis (OSFO). Introducing both ST...
A solution of1a(0.01 mole) and urea or thiourea (0.01 mole) in 30 mL of n-butanol was refluxed with 5 h. The solid that separated was crystallized from ethanol to give compounds2a-b. 3.1.2. 2-(Tetrabromophthalimidomethyl-6-Phenyl-5-Cyano-1,3-Oxazino[4,5-e]-1,3-Pyrimidine-3-[...
3-methyl-1-butanol was the major compound, mainly in A (44%) and in a smaller percentage in B and C (between 34% and 36%). The second major VOM was 2-phenylethanol (flowers odour), which represents about 12%, 13%, and 15% of the total volatile fraction of A, B, and C, resp...
