For an experiment, I need to make the surface of glass coverslips reactive. I would treat multiple coverslips put on a rack dipped in the solution of TMSPM. Since a large volume of solution (around 50-60 ml) would be used, I was wondering if the solution can be reused. Does the solution become unstable after 15 min of preparation and use?
Dear friend Alekhya Hati
The stability and reusability of solutions of 3-(Trimethoxysilyl)propyl methacrylate (TMSPM) in isopropanol depend on various factors such as storage conditions, exposure to air, and presence of impurities.
Generally, solutions of TMSPM in isopropanol are stable for a few days when stored in a tightly closed container at room temperature in the dark. However, the stability can be affected by exposure to air, moisture, and impurities. TMSPM can hydrolyze in the presence of moisture and form undesirable byproducts that can affect the reactivity of the glass surface.
Additionally, exposure to air can cause oxidation of the isopropanol, leading to the formation of peroxides that can also affect the stability and reactivity of the TMSPM solution.
In terms of reusability, it may be possible to reuse the TMSPM solution if it has not been contaminated with impurities or degraded due to exposure to air or moisture. However, the reactivity of the glass surface may decrease with each use, and it is recommended to prepare fresh TMSPM solution for each use to ensure consistent results.
Overall, it is recommended to prepare a fresh solution of TMSPM in isopropanol for each use and store it in a tightly closed container in the dark to ensure stability and prevent contamination.
