%X This dataset "Alkyl Rare Earth Compound Production Process Research and Development Data Set" is mainly aimed at synthesis and purity characterization research in the field of chemical science. It includes synthesis process development and characterization of three types of rare earth alkyl compounds (tris (2-N, N-dimethylaminobenzyl) samarium, tris (2-N, N-dimethylaminobenzyl) yttrium, tris (2-N, N-dimethylaminobenzyl) lanthanum). This data set system integrates the original collected data (production process, characterization results) generated during the research and construction process, including the research and development process report of each alkyl rare earth compound and the third-party testing CMA report, providing scientific researchers with experimental reproduction, Results verification and performance optimization provide complete data support. The characterization of alkyl rare earth compounds is achieved by hydrogen nuclear magnetic resonance spectroscopy, which provides key information including chemical shifts, coupling constants, and integration values. The structural characteristics of alkyl rare earth compounds were determined by analyzing the nuclear magnetic spectra. Based on the proportional relationship between the integrated area of the characteristic signal of the alkyl rare earth compound in the nuclear magnetic resonance spectrum and the number of protons corresponding to the resonance peak, the purity of the alkyl rare earth compound was determined using a standard material (internal standard) of known purity (>98%).
