%X The "Alkyl Rare Earth Compound Synthesis Process Dataset" is mainly aimed at the research of synthesis and purity characterization in the field of chemical science, including the development and characterization of synthesis processes for three types of rare earth alkyl compounds (tris (2-N, N-dimethylaminobenzyl) samarium, tris (2-N, N-dimethylaminobenzyl) yttrium, and tris (2-N, N-dimethylaminobenzyl) lanthanum). This dataset system integrates the raw collected data (production process, characterization results) generated during the research construction process, including the research and development process reports of each alkyl rare earth compound and third-party detection CMA reports, providing complete data support for researchers to carry out experimental reproduction, result verification, and performance optimization. The characterization of alkyl rare earth compounds is achieved through nuclear magnetic resonance hydrogen spectroscopy, which provides key information including chemical shifts, coupling constants, and integral values. By analyzing the nuclear magnetic spectrum, determine the structural characteristics of alkyl rare earth compounds. Based on the proportional relationship between the integrated area of characteristic signals of alkyl rare earth compounds in nuclear magnetic resonance spectra and the corresponding proton numbers that produce resonance peaks, the purity of alkyl rare earth compounds (>98%) is determined using a standard substance (internal standard) with known purity.
