产品介绍 |
四氢呋喃(THF)是一种饱和环醚,主要用作有机溶剂。长期储存时,它会形成有机过氧化物。可通过添加丁基羟基甲苯(BHT)作为稳定剂而抑制这一过程。BHT能去除形成过氧化物所需的自由基。它是各种天然产物(聚醚类抗生素)的关键片段。THF可与硫化氢形成双水合物,其晶体结构已经过三维单晶研究法进行过研究。
Tetrahydrofuran (THF) is a saturated cyclic ether that is mainly used as an organic solvent. When stored for a long time, it forms organic peroxides. This process can be inhibited by adding butylhydroxytoluene (BHT) as a stabilizer. BHT removes free radicals needed to form peroxides. It is a key fragment of various natural products (polyether antibiotics). THF can form double hydrates with hydrogen sulfide, and its crystal structure has been studied by three-dimensional single crystal method. |
