bronopol 洗剂为一新型广谱抗菌消毒剂。本文采用反相离子对高效液相色谱技术,用化学动力学恒温加速实验法,在85,90,95,100℃4个温度下测定了 bronopol 洗剂不同受热时间的含量变化。结果表明 bronopol 洗剂是一稳定的制剂,其 K25°=5.36×10~(-6)(h~(-1)),t~(25°)_(0.9)=19700h。本文建议 bronopol 洗剂暂定有效期2年。 Bronopol lotion is a new broad-spectrum antibacterial disinfectant. In this paper, ion-pair reversed-phase high performance liquid chromatography was used to determine the content of bronopol lotion during different heating time at four temperatures of 85, 90, 95 and 100 ℃ by means of thermostatic accelerated chemical kinetics. The results showed that bronopol lotion was a stable preparation with K25 ° = 5.36 × 10 -6 h -1 and t 25 ° _ 0.9 = 19700 h. This paper suggests bronopol lotion is tentatively valid for 2 years.
