The tautomeric equilibrium between the azo type and the hydrazone type of these compounds in different solvents and different acidity has also been studied.

对不同溶剂。不同碱度溶液中的偶氮式及腙式互变异构平衡进行了研究。

The two now isonicotnic acid hydrazone and N-oxide isonicotinic acid hydrazone of ethyl furoyl acetates were synthesised. The condensations were carried out in ethyl alochol medium.

合成了呋喃甲酰异烟酰腙和呋喃甲酰N-氧化异烟酰腙。缩合反应醇中进行。
