Anhydrous - Alfa Aesar

Anhydrous solvents are high pure solvents made with low water content. Anhydrous solvents produced in laboratories use complex and difficult processes to reduce the moisture content. Different dehydrating techniques are used to minimise the moisture content include column distillation, addition of molecular sieves and distillation over metallic catalyst.

Commercially available anhydrous solvents can be directly used in reactions as further purification is not required. These anhydrous solvents are used in moisture sensitive reactions in both organic and in-organic synthesis and analytical fields where yields are maximized by reducing the side reactions.

Anhydrous solvents normally have the water content in the range below 50 ppm. Care shall be taken while opening the anhydrous solvents at ambient temperature as they tend to absorb moisture from the atmosphere.
