名稱:2,2-聯吡啶
 

純度:AR 包裝:25kg
CAS:          366-18-7
分子式:      C10H8N2
分子量:      156.18

中文名稱:  2,2'-聯吡啶
                   2,2-聯吡啶
                    α,α'-聯氮雜苯

英文名稱:  2,2'-Bipyridine
                   2,2'-Bipyridyl
                   2,2'-bipyridin
                   2,2'-dipyridine
                   2,2'-dipyridyl

性質描述:  白色至淺紅色結晶性粉末。熔點69.5℃,沸點272.5℃。易溶于乙醇、乙醚、苯、氯仿和石油醚,1份2,2'-聯吡啶約溶于200份水。

     2,2'-聯吡啶是聯吡啶異構體之一,無色固體。它是一個雙齒螯合配體,可以和很多金屬離子形成配合物,因此可作氧化還原指示劑。與釕和鉑的配合物具有很強的發光性質,可能有潛在應用。

        bipy及其衍生物可通過吡啶與雷尼鎳作用脫氫得到。常見的2,2'-聯吡啶配合物包括:Mo(CO)4(bipy),類似Mo(CO)6;RuCl2(bipy)2,合成前體;[Ru(bipy)3]Cl2,常用的發光物質;[Fe(bipy)3],用于亞鐵離子的比色分析。三(bipy)類型的配合物通式為[M(bipy)3](M = 金屬離子:Cr、Fe、Co、Ru、Rh等),中心原子為八面體型六配位,有兩個對映異構體。
制備方法:將無水吡啶與無水三氯化鐵混合,加熱反應,冷卻固化得紅黑色結晶。用蒸汽加熱除去過量的吡啶。蒸出α,α'-聯吡啶。再加氫氧化鈉用乙醚提取,除去乙醚,得粗品。用無鐵活性炭脫色,過濾,得白色葉片狀結晶,即為純品2,2'-聯吡啶。

Fire Fighting Measures
【Flash Point】121
【Fire Fighting】Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Runoff from fire control or dilution water may cause pollution. Extinguishing media: Use agent most appropriate to extinguish fire. In case of fire, use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam.
【Fire Potential】Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
