Neodymium Carbocxylates (Neodecanoate and 3,5,5-Trimetylhexanoate) for Development of Nd-Loaded Liquid Organic Scintillators
摘要
Abstract
The synthesis of neodymium carboxylates (neodecanoate and 3,5,5-trimethylhexanoate) and their application in developing Nd-loaded liquid organic scintillators are discussed. Neodymium carboxylates were obtained through a one-step synthesis (for 3,5,5-trimethylhexanoate) and a two-step synthesis (for neodecanoate). The composition of the synthesized compounds was confirmed using IR spectroscopy, elemental analysis, and MALDI-TOF MS. To incorporate neodymium carboxylates into a liquid organic scintillator, an additional solvent, tributylphosphate, was proposed. It was demonstrated that the scintillator’s light output, when using this solvent, is more than 60% higher up to a neodymium concentration of 12 g/L, compared to without it.
