General description
The trimethyl phosphate levels in environmental water was determined by direct analysis real-time ionization source interfaced with a triple quadrupole mass spectrometer (DART-MS/MS) with multiple reaction monitoring (MRM).
Application
- Enhanced Battery Performance: Trimethyl phosphate is utilized to manipulate the ionic conductivity and interfacial compatibility in polymer-in-dual-salt electrolytes, significantly extending the operable temperature range of quasi-solid metal batteries (Lin et al., 2024).
- Thermochemical Properties Analysis: Research on trimethyl phosphate′s thermochemistry properties and rate kinetics, particularly H-Atom Abstraction reactions, provides valuable insights into its stability and reactivity, which are crucial for various chemical synthesis applications (Bruce and Li, 2023).
- Organophosphorus Flame Retardants Detection: Trimethyl phosphate is explored for its role in the screening of organophosphorus flame retardant residues in food samples, specifically rice, utilizing advanced chromatographic techniques to ensure food safety and compliance with environmental regulations (Li et al., 2023).
- Interfacial Reaction Regulation in Batteries: The study on regulating interfacial reactions through electrolyte chemistry, involving trimethyl phosphate, highlights its potential to create gradient interphases for low-temperature zinc metal batteries, contributing to enhanced battery safety and efficiency (Wang et al., 2023).
