AB  - This dataset, "Research and Development Process Dataset for Water soluble Rare Earth Compounds Production Process," is mainly aimed at the synthesis and purity characterization research in the field of chemical science. It includes the development and characterization of synthesis processes for three types of water-soluble rare earth compounds (yttrium trifluoromethanesulfonate, scandium trifluoromethanesulfonate, ytterbium trifluoromethanesulfonate). 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 water-soluble 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 water-soluble compounds of yttrium and scandium were characterized by nuclear magnetic resonance hydrogen spectroscopy, providing key information including chemical shifts, coupling constants, and integral values. By analyzing the nuclear magnetic spectrum, the structural characteristics of water-soluble rare earth compounds scandium trifluoromethanesulfonate and yttrium trifluoromethanesulfonate were determined. Based on the proportional relationship between the integrated area of characteristic signals of water-soluble rare earth compounds in nuclear magnetic resonance spectra and the corresponding number of fluorine atoms that produce resonance peaks, the purity of water-soluble rare earth compounds (>98%) is determined using a standard substance (internal standard) with known purity. Inductively coupled plasma atomic emission spectrometer was used to quantitatively analyze the rare earth yttrium in ytterbium trifluoromethanesulfonate, and the purity of ytterbium trifluoromethanesulfonate was determined to be greater than 98%.
