Development of an Indicating Slide for EO Alkylation Reaction
Using the alkylation reaction of NBP with EO as the mechanism,a simple indicator slide that can indicate the alkylation reaction of EO in real time was prepared,and the color and absorbance effects of the NBP content,alkaline regulator,and film thickness were investigated and characterized by UV-visible spectrophotometer.The results showed that the absorbance was approximately linearly related to the reaction time at 2%～3%NBP content,3%～4%triethanolamine content,and 150 μm film thickness.The indicator slide outputs resistance signal through light source and photoresistor.It can be future used in real-time high-volume EO sterilization tracking without manual reading.
