This dataset "Data Set on Research and Development Process of Rare Earth Hydride Production Process" is mainly aimed at research on synthetic purity characterization in the field of chemical science, and includes the synthesis of a class of rare earth hydride (N, N-dimethylethylenediamine-bridged bis aryloxyyttrium hydride). Process development and characterization. This dataset 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 the rare earth hydride and the third-party testing CMA report, providing scientific researchers with experimental reproduction and result verification., performance optimization provides complete data support. Rare earth hydride was characterized by 1H nuclear magnetic resonance spectroscopy, providing key information including chemical shifts, coupling constants, and integration values. The structural characteristics of the rare earth hydride were determined by analyzing the nuclear magnetic spectrum. Based on the proportional relationship between the integrated area of the characteristic signal of the rare earth hydride in the nuclear magnetic resonance spectrum and the number of protons corresponding to the resonance peak, the purity of the rare earth hydride (>98%) was determined using a standard material (internal standard) of known purity.

The process of collecting nuclear magnetic resonance data is as follows: in a glove box environment, add a quantitative sample to a J-Young nuclear magnetic tube and dissolve it in approximately 0.6 mL of dried deuterated benzene; Subsequently, about 10 μ L of trimethylbenzene was added as an internal standard, and the sample was characterized by ¹ H NMR at room temperature using a Bruker AV Neo 600 liquid superconducting nuclear magnetic resonance spectrometer. Two parallel tests were conducted, and the original spectral data was reduced and processed using MestReNova software.
The nuclear magnetic resonance data was analyzed using MestReNova software, and the original spectrum files in ". nova" format were processed. Determine the structure of the target compound through spectral fitting and peak assignment analysis. Based on the proportional relationship between the integrated area of characteristic signals of rare earth hydrides in nuclear magnetic resonance spectra and the corresponding proton number of resonance peaks, using known purity of toluene as the standard substance, the purity of rare earth hydrides was calculated using nuclear magnetic quantification method, and the result was greater than 98%.
