19 Μαρ 2018 · Here we report the toluene-producing enzyme PhdB, a glycyl radical enzyme of bacterial origin that catalyzes phenylacetate decarboxylation, and its cognate activating enzyme PhdA, a radical S...
7 Ιαν 2021 · This paper reported the purification of toluene waste gas by liquid-phase absorption and anoxic denitrification. In this work, two same biofilm reactors were set to treat toluene waste gas, one of which was added into nitrate as an electron acceptor.
15 Οκτ 2024 · Industrial toluene was purified to reagent-grade by sorption on granulated activated carbon (GAC). Order of impurities in terms of sorption affinity onto GAC is determined as MBT > ECP > XYL. Dynamic sorption was performed in a pilot-scale to treat a large volume (∼900 L) of industrial toluene.
Toluene (/ ˈtɒl.juiːn /), also known as toluol (/ ˈtɒl.ju.ɒl, - ɔːl, - oʊl /), is a substituted aromatic hydrocarbon [15] with the chemical formula C6H5CH3, often abbreviated as PhCH3, where Ph stands for phenyl group. It is a colorless, water -insoluble liquid with the odor associated with paint thinners.
30 Απρ 2023 · Common solvent pairs include ethyl acetate and hexane, toluene and hexane, methanol and dichloromethane, and water and ethanol. Now that you understand the principles of recrystallization, let’s go through a procedure for purification of an organic compound by recrystallization.
Highly- purified toluene (reagent grade and nitration grade) contains less than 0.01% benzene, while industrial grade and 90/120 grade toluene contain a significant quantity of benzene. The 90/120 grade contains as much as 25% (US NIOSH, 1973).
28 Νοε 2023 · Toluene can be purified by passage through a tightly packed column of Fuller's earth. Rapid purification: Alumina, CaH2 and 4A molecular sieves (3% w/v) may be used to dry toluene (6hours stirring and standing).
