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.

成了呋喃甲乙酸乙异烟呋喃甲乙酸乙N-氧化异烟。缩在乙醇中进行。

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

对它们在不同溶剂。不同酸碱度溶液中的偶氮式及式间互变异构平衡进行了研究。
