A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, HPLC of Formula: C15H10ClN3, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 128143-89-5, Name is 4′-Chloro-2,2′:6′,2”-terpyridine, molecular formula is C15H10ClN3. In an article, author is Lan, Tianyu,once mentioned of 128143-89-5.
Synthesis and ethylene polymerization reaction of dendritic titanium catalysts
The 1.0 G dendrimer (C22H48N10O4),3,5-di-tert-butylsalicylaldehyde and TiCl4 center dot 2THF were used as the synthetic materials, and the dendritic salicylaldehyde imide ligand with substituent hindrance and its titanium catalyst were synthesized by the condensation reaction of schiff base. The structure of the synthesized products was characterized by infrared spectroscopy, nuclear magnetic resonance hydrogen spectroscopy, ultraviolet spectroscopy, electrospray mass spectrometry, and inductively coupled plasma mass spectrometry, The actual structure is consistent with the theoretical design structure. Activated methylaluminoxane (MAO) was used as a catalyst precursor for ethylene polymerization in the process of ethylene catalytic. The effects of ethylene polymerization were studied in terms of the Al/Ti molar ratio, reaction time, reaction temperature, polymerization pressure, and ligand structure of the catalyst. The results show at the reaction temperature of 25 degrees C, the reaction time was 30 min, and the ethylene pressure was 1.0 MPa and Al/Ti was 1,000, the catalytic activity can reach 78.56 kg PE/(mol Ti.h). Furthermore, high-temperature GPC-IR, DSC, and torque rheometer were used to characterized the microstructure, thermal properties, and viscoelastic state of polyethylene samples obtained. The results showed that the product was ultra-high-molecular-weight polyethylene.
