以丙酮氰醇和水合肼为原料缩合生成二异丁腈肼，结晶母液一般作为废水处理。通过对二异丁腈肼结晶母液特殊处理，用配位滴定法测定了丙酮氰醇的残留量，并对母液中水合肼的含量作出推算，为优化偶氮二异丁腈工艺，进行清洁工艺设计提供相关基础数据。%In the production of 1,2-bis(2-cyano-2-propyl)-hydrazine from acetone cyanohydrin and hydrazine hydrate by condensation reaction, crystallization mother liquor is generally treated as wastewater. In this paper, after special treatment of 1,2-bis(2-cyano-2-propyl)-hydrazine crystallization mother liquor, residual amount of acetone cyanohydrin was determined by complexometric titration method, and calculation of hydrazine hydrate content in the mother liquor was carried out, which provide relevant data for the optimization of azobisisobutyronitrile process and the design of cleaner process.
