摘　　要：以铍块、浓盐酸、乙醚、甲基镁、甲酸等为原料合成了含铍先驱体。采用XRD、元素分析仪、ICP、红外光谱对先驱体的组成、结构进行了表征。结果表明,先驱体中含有有机铍并且以-C-Be-C-形式存在。此外,所合成的先驱体经纺丝后可得到长度50～80cm、直径约100μm的有机纤维。The beryllium containing precursor was synthesized using beryllium blocks, concentrated hydrochloric acid, methyl magnesium and formic acid as the staring materials. The chemical composition and structure were investigated using XRD, mass spectroscopy, ICP and IR-spectroscopy. The results indicate that the precursor con- tains organic beryllium and Be is in the form of -C-Be-C- in the pendant. The organic fiber with a length of 50-80 cm and a diameter of about of 100 μm can be obtained by glass spinning.
