In this study, solid-state 13C NMR spectroscopy was utilized to characterize and identify the metal-ester coordination in active fourth-generation (phthalate) Ziegler-Natta (ZN) catalysts. It is known that different donors affect the active species in ZN catalysts. However, there is still limited data available of detailed mol. information on how the donors and the active species are interacting. One of the main goals of this work was to get better insight into the interactions of donor and active species. Based on the anisotropy tensor values (δ11, δ22, δ33) from low magic-angle spinning 13C NMR spectra in combination with chem. shift anisotropy calculations (δ aniso and η), both the coordinative metal (Mg/Ti) and the symmetry of this interaction between metal and the internal donor in the active catalyst (MgCl2/TiCl4/electron donor) system could be identified. This study involved multiple reactions and reactants, such as 2-Ethylhexyl benzoate (cas: 5444-75-7Related Products of 5444-75-7).
2-Ethylhexyl benzoate (cas: 5444-75-7) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Related Products of 5444-75-7
