Desiccants can absorb water and bind it chemically (reversibly or irreversibly) or physically. The main desiccants can be subdivided into four categories:
• non-renewable chemical desiccants
• renewable chemical desiccants
• silica gels
• molecular sieves
Many reaction mechanisms require deprotonation so that the desired reaction can take place. The strength of the required bases depends entirely on the application. Carl ROTH supplies a wide selection of bases which play an important role in organic synthesis.
