Green Synthesis Of Triazine Compounds And Diazo-Compounds By Using Methyl Nitrite

In this dissertation, synthesis of triazenes and diazo-compounds by using methyl nitrite were investigated.Firstly, synthesis of triazene compounds using methyl nitrite as a diazotization reagent was produced by hydrochloric acid with sodium nitrite and methanol, through review of the Green Chemistry and the improvement of the diazotizatization methods. It has no nitric oxide and nitrogen dioxide were produced and less side reactions and good yield in this process.Secondly, synthesis and studies of the general diazo-compounds by using methyl nitrite. The diazonium salts were produced by methyl nitrite under low temperature and straightly used in the coupling reactions. It is not only make the operation easy, but also can obtain the produces without prorification by controlling the pH of the reaction mixture. This is consistent with Green Chemistry.Thirdly, Green synthesis and studies of azo compounds containing sulfo functional group were synthetized by aromatic amines or phenols and diazonium salt produced by the reaction of para-aminophenylsulfic acid with methyl nitrite. The produces can be obtained without further isolation. It is easy to manipulate and post process.The evident advantages of the method for preparation of the above compounds are mild reaction conditions, good yields, environmental benign, and easy to work up...
