Piperidine was first reported in 1850 by the Scottish chemist Thomas Anderson and again, independently, in 1852 by the French chemist 2403-88-5, formula is C9H19NO, Name is 2,2,6,6-Tetramethyl-4-piperidinol. Auguste Cahours, who named it. Both of them obtained piperidine by reacting piperine with nitric acid. Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol.
Li, Xiaoying;Yu, Zhou;Chen, Qincheng;Wang, Chen;Ma, Li;Shen, Guoqing research published 《 Kill three birds with one stone: Iron-doped graphitic biochar from biogas residues for ammonium persulfate activation to simultaneously degrade benzo[a]pyrene and improve lettuce growth》, the research content is summarized as follows. A graphitized magnetic biochar material, Fe-impregnated biochar (FBC), was synthesized using biogas residue, a product of food waste after anaerobic fermentation The FBC coupled with ammonium persulfate (APS) exhibited excellent performance in the catalytic degradation of benzo[a]pyrene (BaP), a pentacyclic polycyclic aromatic hydrocarbon (PAH). In the FBC-APS system, the pyrolysis temperature of biochar, the initial pH, and the FBC and APS dosages were all influencing factors for Bap degradation The FBC at the pyrolysis temperature of 700°C performed the best catalytic performance, and FBC-APS efficiently degraded BaP at a wide pH range of 3-11. Results from quenching experiments, ESR measurement, and electrochem. anal. were used as the basis to propose the possible degradation mechanisms of BaP by FBC-APS, including the radical and non-radical pathways. The radical-induced oxidation was attained by SO·-4 and O·-2. The non-radical pathway involved two aspects, one contributed by 1O2 and the other achieved through electron transfer. Five BaP intermediates were tentatively determined Finally, FBC-APS was applied to BaP-polluted soil, and the overall degradation rate reached 91.7% after 72 h. Lettuce growth experiment showed that FBC-APS enhanced soil nitrogen and potassium availability and lettuce growth. In summary, FBC-APS application to soil can degrade BaP, improve the manurial effect, and solve environmental problems brought by biogas residues, i.e., killing three birds with one stone.
Recommanded Product: 2,2,6,6-Tetramethyl-4-piperidinol, 2,2,6,6-Tetramethyl-4-piperidinol(TEMPO) is a useful research compound. Its molecular formula is C9H19NO and its molecular weight is 157.25 g/mol. The purity is usually 95%.
TEMPO is an intermediate used in the preparation of Piperidinyloxy free radical derivatives.
TEMPO is an organic compound that acts as a radical scavenger. It is stable in the presence of water and air and can be used for the inhibition of bacterial growth. TEMPO reacts with reactive intermediates to form non-reactive substances and terminate chain reactions. This process is optimal at temperatures between 0°C and 40°C and pH values between 3.5 and 7.5. TEMPO has been shown to inhibit the growth of bacteria by reacting with reactive molecules such as amines, chlorides, or low energy radicals in aqueous solution. TEMPO also has genotoxic activity that inhibits DNA synthesis in bacterial cells through oxidation of guanine residues on DNA molecules., 2403-88-5.
