Chemistry, like all the natural sciences, begins with the direct observation of nature¡ª in this case, of matter.14691-89-5, Name is 4-Acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl, SMILES is CC1(C)CC(NC(C)=O)CC(C)(C)N1[O], belongs to piperidines compound. In a document, author is Revathi, B. K., introduce the new discover, Application In Synthesis of 4-Acetamido-2,2,6,6-tetramethylpiperidine 1-oxyl.
Crystal growth and characterization of new nonlinear optical piperidine derivative: (4-hydroxypiperidin-1-yl)(4-methylphenyl) methanone
Organic compound (4-hydroxypiperidin-l-yl)(4-methylphenyl) methanone[HPMP] with molecular formula C13H17N O-2 was synthesized using Scholten-Boumann condensation reaction method. The single crystals were grown using slow evaporation solution growth technique. Single crystal XRD study shows that the compound crystallizes in the orthorhombic system with a space group Pca2(1).H-1 and C-13 NMR spectra were recorded to identify the various types of protons and carbons present in the compound and confirm the chemical structure. The Various functional groups present in the compound were identified using recorded FT-IR spectrum. The UV-Visible spectrum study reveals that the crystal is transparent in the entire visible region and the absorption is observed at 236 nm. The PL spectrum shows the emission takes place at 432 nm. The thermal study reveals that the thermal stability of the crystal is good. The Kurtz powder second harmonic generation (SHG) test shows that the HPMP is NLO active and its SHG efficiency is 1.86 times that of KDP. The micro hardness test was carried out and the work hardening coefficient value (n) of the crystal was found to be 2.20. This indicates that the crystal is hard and is suitable for device application. (C) 2017 Elsevier B.V. All rights reserved.
The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.
