摘　　要：采用非水溶剂体系盐酸羟胺法测定工业用碳五烯烃中羰基化合物的含量，讨论了温度和停留时间对该法的影响及该方法的精密度，结果表明利用该法进行测定，标准偏差为0．013～1．07mg／kg，相对标准偏差为0．24％～4．16％，回收率为93．8％～100．3％，能够满足碳五烯烃中羰基化合物含量的测定要求。与水溶剂体系盐酸羟胺法相比，其检测限低，更适合微量羰基化合物含量的测定。The carbonyl compound content in industrial C5 oletin was determined with non - aqueous solvent metnott of hydroxylamine hydrochloride. The effects of temperature and staying time on the method, and precision of the method were discussed. Result showed that the standard deviation was 0. 013 ~ 1.07 mg/kg, relative standard deviation was 0. 24% - 4. 16% , and recovery rate was 93.8% - 100. 3% , which could meet the demand of determining carbonyl compound in C5 olefin. Comparing with aqueous solvent method of hydroxylamine hydrochloride, this method had lower detection limit, and was more suitable for determination of micro carbonyl compound content.
