摘　　要：本文通过实验探究了不同浓度下滴定剂与丙酮、氯仿及多聚甲醛的热效应关系,找出了热反应发生的滴定剂浓度下限,在此基础上以最低下限浓度滴定剂对加入不同催化指示剂的喷气燃料进行滴定,结果表明多聚甲醛作为催化指示剂,温度催化性能突出,适用于喷气燃料微量酸值的测定。In this paper,the thermal effects of the titrant and acetone-chloroform,paraformaldehyde at different concentrations were investigated,which found the lowest concentration of the titrant in the thermal reaction. On the basis of this,the jet fuel with different catalytic indicators was titrated by the corresponding lowest concentration titrant. The results showed that when paraformaldehyde was used as catalytic indicator,the thermometric catalytic performance is prominent,and it is suitable for the determination of the acid value of the jet fuel.
