Algemene informatie
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.
