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.

合成了呋喃酸异烟腙和呋喃酸N-氧化异烟腙。缩合反应在醇中进。

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

们在不同溶剂。不同酸碱度溶液中的偶氮式及腙式间互变异构平衡进了研究。
