Industrially, piperidine is produced by the hydrogenation of pyridine, usually over a molybdenum disulfide catalyst: C5H5N + 3 H2 → C5H10NH. 2403-88-5, formula is C9H19NO, Name is 2,2,6,6-Tetramethyl-4-piperidinol. Pyridine can also be reduced to piperidine via a modified Birch reduction using sodium in ethanol. Application of C9H19NO.
Tan, Chaoqun;Xu, Tianhui;He, Huan;Xu, Qinglong;Fang, Chao;Du, Erdeng;Deng, Jing;Chu, Wenhai research published 《 Bimetallic oxychloride as an efficient oxone activator: Radical and non-radical oxidation of non-steroidal anti-inflammatory drugs》, the research content is summarized as follows. A novel iron-cobalt mixed oxychloride (CoFeOCl) nanosheet, with a plane size in the ranges of 0.2-1.0 μm and a thickness of 30-40 nm, was manufactured firstly and employed as catalyst for peroxymonosulfate (PMS) activation. The CoFeOCl/PMS system exhibits excellent catalytic activity for non-steroidal anti-inflammatory drugs removal at buffered pH 5.5-8.5 with extremely low catalyst dosage (0.03 g/L). The mechanism of PMS activation by CoFeOCl indicated that ·OH and 1O2 played a key role at pH 5.5-7.0 and pH 8.5 resp., and O–2· was involved for all pHs. The cycle of Co2+-Co3+ and Fe2+-Fe3+ were answerable to ·OH and 1O2 generation. Furthermore, CoFeOCl/PMS pre-oxidation before chlorination engendered in a reduce in the concentration of total disinfection byproducts (DBPs) at pH 8.5. A feasible reaction pathway of DBPs formation was examined with d. functional theory (DFT) calculation The findings provide a new routine for effective PMS activation.
Application of C9H19NO, 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.
