When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low.

在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液

The wastewater from gum benzion production contains benzaldehyde, cyanide, gum benzoin and ethyl benzoate. When the cyanide is determined by isonicotinic acidpyrazalon method, the ethyl benzoate is distilled and goes into NaOH absorption liquid with cyanide in the process of predistillation, because its boiling point is low. Thus the absorption liquid produces a great deal of foam and feculence.

摘要］有机化工产品安息香生产废水中含有苯甲醛、氰化物、安息香和苯甲酸乙酯，在用异烟酸吡唑啉酮法对其进行氰化物测定时，由于油酯类的沸点较低，在预蒸馏过程中被蒸出和氰化物一起进入NaOH吸收液，使得吸收液产生大量泡沫和沉淀，严重干扰后续比色测定。
