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

对在不同溶剂。不同酸碱度溶液中的偶氮式及腙式互变构平衡进行了研究。

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.

合成了呋喃甲酰酸烟酰腙和呋喃甲酰酸N-氧化烟酰腙。缩合反应在醇中进行。
