Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 81058-27-7, Name is (2R,3R,4S,5R,6R)-2-Bromo-6-((pivaloyloxy)methyl)tetrahydro-2H-pyran-3,4,5-triyl tris(2,2-dimethylpropanoate), molecular formula is , belongs to chiral-nitrogen-ligands compound. In a document, author is Yan Yilun, COA of Formula: C26H43BrO9.
Synthesis of a beta-Ketoenamine-linked Chiral Covalent Organic Framework and Its Application in Capillary Gas Chromatography
A new beta-ketoenamine-linked chiral covalent organic framework (COF), namely TfpMth COF, was prepared by the reaction of 1, 3 ,5-triformylphlomglucinol(Tfp) with (S)-2,5-bis(2-methylbutoxy)terephthalohydrazide (Mth). The obtained TfpMth COF powder was characterized by various techniques such as powder X-ray diffraction analysis, Fourier transform infrared spectrometer (FTIR), thermogravimetric analysis (TGA), nitrogen adsorption-desorption measurement and so on, indicating its virtue of good crystallinity, high porosity, and excellent thermostability. Thus, we used TfpMth COF as a new stationary phase to prepare the TfpMth COF-bound capillary column by an in situ growth method. A series of linear and branched alkanes and alcohols, as well as mixtures of benzene and cyclohexane, ethylbenzene and styrene can be separated using the TfpMth-bound capillary column. This result provides a new idea for the application of beta-ketoenamine-linked COF in chromatographic separation, and also gives a reference for the study of novel gas chromatographic stationary phases.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 81058-27-7, in my other articles.
