洁消精溶液的化学稳定性研究

Chemical stability of Jie Xiao Jing solution

洁消精系由高效有机含氯消毒剂、合成表面活性剂、助洗剂及其它辅料组成的一种新型消毒清洗剂。它不但具有较强的氧化杀菌、去污垢能力,且无腐蚀、无污染而可替代传统的浓硫酸重铬酸钾洗液用于输液瓶等其它器具的除垢、去热原处理。因其氧化杀菌的主要成分为有效氯,不甚稳定,它的含量高低将直接影响杀菌效果。所以。

The chemical stability of Jie Xiao Jing solution wasstudied by accelerated test with classical isothermal method.Results of the study showed that the decomposition of Jie Xi-ao Jing solution was found to be a pseudo-first reaction, theactivation energy being 20. 4 Kcal·mol^(-1) and the reactionrate constant at 25℃ being 1. 9312×10^(-3)(h^(-1). It is rec- ommended that the shelf life of Jie Xiao Jing solution is 2.3days. The samples were placed on probation at the room tem-perature that the shelf life was found to be 2.5 days. Therewas no significant difference between these two results.
