Аннотация:Synthine and T-6 propellant are studied as new basic solvents for creating liquid organicscintillators. The light attenuation length in these solvents (both those obtained from the manufacturer and those subjected to chromatographic purification on Al2O3) was measured along with the relative light yield of scintillators based on them. The chemical composition of synthine was determined by the method of chromato-mass spectrometry and UV spectrophotometry. A Nd-loaded scintillator (CNd 9 g/l) based on a synthine–pseudocumene mixture was created, and its light yield (LY 60%) was measured with respect to a scintillator based on linear alkyl benzene (LAB).
