(口恶)二唑-1,3,4和苯骈(口恶)唑-1,3的衍生物,作为有机闪烁剂,被广泛地用于原子能、医学、考古、探矿、农业等各个领域。尤其作为激光染料,用于激光技术方面,具有独特的优点。 目前,这类物质主要靠国外进口。近几年来,我国科学工作者,已研试出一批性能较好的(口恶)二唑-1,3,4和苯骈嚼唑-1,3的衍生物。现在,对于这些较难提纯的化合物的分离分析工作,亟待解决。 (Oral Ea) 1,3,4-oxadiazole-1,3,4-benzoxazole-1,3 derivatives are widely used as organic scintillators in various fields such as atomic energy, medicine, archeology, prospecting and agriculture . Especially as a laser dye for laser technology, it has unique advantages. At present, these substances mainly rely on foreign imports. In recent years, scientists in our country have researched a series of derivatives with better performance (ox clams), 1,3,4 and benzocycloazole-1,3. Now, the separation and analysis of these more difficult to purify the compounds, urgent solution.
