3,4-二(吡嗪-2'-基)氧化呋咱的合成及热分解机理
Synthesis and Thermal Decomposition Mechanism of 3,4-Bis(pyrazine-2'-y1)furoxan
摘要
Abstract
3,4-Bis(pyrazine-2'-y1)furoxan(BPF) was synthesized using self-synthetic 2-chloroximopyrazine as starting material via cyclization reaction.The structure of target compound BPF was characterized by the means of IR,1H NMR,13C NMR,elemental analysis and MS.The mechanism of cyclization reaction was investigated.The synthetic conditions of cyclization reactions were optimized.The thermal decomposition mechanism of target compound was studied using a variety of thermal analysis methods just as differential scanning calorimetry(DSC) and thermogravimetric(TG-DTG).Results show that the optimum conditions of cyclizations are that diethyl ether is solvent,3% Na2CO3 aqueous solution is deacidification catalyst,nactual ∶ ntheory (the amount of Na2CO3) is 1.10,reaction temperature is 2-10 ℃,reaction time is 4 h,and the yield of BPF is about 75.6%.The thermal decomposition of target compound BPF is firstly occurred at N-O bond of furoxano ring.关键词
