Reaction Steps
The procedure in Example 2 was repeated except that propylene glycol was replaced by 2,3-butanediol, water was not used and the mixing (molar) ratio of the mixed gas was changed to ethylene diamine: 2,3-butanediol:nitrogen=1:1.2:0.7 to produce 2,3-dimethylpyrazine. The rate of conversion was 100% and the yield of 2,3-dimethylpyrazine was 72%.
