Sdudies On Microwave-assisted Oxidation Of Diarylalkynes To 1,2-diaryldiketones And Polymerization Of C₅ Petrleum Pitch

The thesis consists of two parts:The first part is the study of microwave-assisted oxidation of internal alkynes to 1,2-diaryldiketones with DMSO/I₂.The first chapter introduces the evolvement of oxidation of internal alkynes to 1,2-diaryldiketones including oxidants contain metals and nonmetals.The second chapter introduces the process and the results of microwave-assisted oxidation of internal alkynes to 1,2-diaryldiketones with DMSO/I₂ in detail.We synthesized a range of 1,2-diaryldiketones using 50%amount I₂ in DMSO under microwave irradiation.The attractive features of this method were the short reaction times,good yields,low cost and easy preparation.All those mentioned compounds have been determined by ¹H NMR,¹³C NMR,FAB,IR and EA.The second part is the study on the dimer of C₅ petroleum pitch.The first chapter introduces the analysis of the composing of C₅.The second chapter introduces the synthesis of standard sample of C₁₀ and the analysis of the mainly composing of them. The third chapter introduces the active and relationship of the materials.The results of this part have referenced value to industrial production.
