Abstract

This project is aimed at developing a research study that explores the potential of Mass Spectrometry, in its classic version (MS) and its multidimensional sequential version (MSn), in its different application areas: a - monitoring of volatile organic compounds (VOCs) in water. In this area we intend to carry out more specifically the following projects. 1 - monitoring of VOCs in drinking water, mineral water, swimming pool water after treatment, and others; 2 - monitoring of VOCs in soil using a technique derived from CT-MIMS. 3 - study by MIMS and/or CT-MIMS of the destruction of volatile organic compounds in gaseous phase and determination of the products and mechanisms of reaction. 4 - studies of the efficiency and kinetics and the monitoring of the chemical, catalytic and/or biological processes of destruction of VOCs in water. b - study of the reaction between ions and molecules in the gaseous phase. In this area we intend to carry out more specifically the following projects. 1- reactivity of distonic acylium ions in cycloaddition [4+2], acetalization and transacetalization reactions. 2 - study of the formation, stability and reactivity of R-SO2+ ions in the gaseous phase. 3 - applications of the reaction of acetalization and transacetalization with acylium ions in the identification of diols, and cyclic acetals and cetals in the gaseous phase. 4 - affinities of ions for pyridines in the gaseous phase. 5 - cycloaddition reactions [3+2] of ketones and sulfoxides activated with CH2-O-CH2+.
