Achieving a dry environment can be done through various methods: 1. Dehydration of Reactants and Catalysts: Pre-treating the reactants and catalysts by heating or using desiccants to remove moisture. 2. Use of Inert Atmospheres: Employing inert gases such as nitrogen or argon to displace moisture-laden air. 3. Controlled Reaction Conditions: Utilizing reactors or setups that maintain low humidity levels, such as glove boxes or dry chambers.
