AB  - This dataset "Research and Development Process Dataset for Rare Earth Borohydride Production Technology" is mainly aimed at the synthesis and purity characterization research in the field of chemical science, including the development and characterization of a type of rare earth borohydride (N, N-dimethylethylenediamine bridged biaryloxyborohydride yttrium) synthesis process. This dataset system integrates the raw collected data (production process, characterization results) generated during the research construction process, including the research and development process report of the rare earth borohydride and the third-party detection CMA report, providing complete data support for researchers to carry out experimental reproduction, result verification, and performance optimization. The nuclear magnetic resonance hydrogen spectrum of rare earth borohydride compounds was characterized, providing key information including chemical shifts, coupling constants, and integral values. By analyzing the nuclear magnetic spectrum, determine the structural characteristics of rare earth borohydride compounds. Based on the proportional relationship between the integrated area of the characteristic signals of rare earth borohydride compounds in nuclear magnetic resonance spectra and the corresponding proton numbers that produce resonance peaks, the purity of rare earth borohydride compounds (>98%) is determined using a standard substance (internal standard) with known purity.
