N-(2-Nitrophenylcarbamothioyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2012
Dans le composé du titre, C(9)H(9)N(3)O(3)S, le cycle benzénique et l'unité N-carbamothio-ylacétamide sont orientés selon un angle dièdre de 54,82 (4) °. L'angle dièdre entre le cycle et son groupe nitro attaché est de 28,54 (12) °. Une liaison hydrogène N-H ™ (O,O) bifurquée intramoléculaire génère deux cycles S(6).

N-(2-Methylphenylsulfonyl)acetamide [PDF]

Acta Crystallographica Section E Structure Reports Online, 2011
In the mol-ecular structure of the title compound, C(9)H(11)NO(3)S, the N-H and C=O bonds are anti to each other, while the amide H atom is syn with respect to the ortho-methyl group in the benzene ring. The C-S-N-C torsion angle is -58.2 (2)°, indicating a twist in the mol-ecule.

Synergism and Radicals Dynamics in the Efficient Degradation of Basic Blue 41 via UV/Chlorine Process: Dependence on Processing Conditions

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT The UV/chlorine process, a promising advanced oxidation process, demonstrates remarkable synergism and radical dynamics for the efficient degradation of Basic Blue 41 (BB41). This study investigates the effects of processing conditions, including solution temperature (25°C–45°C), pollutant dose (10–40 mg/L), chlorine concentration (100–1000 μM)
