An oil drying agent, also known as siccative, is a coordination compound that accelerates the hardening of drying oils, often as they are used in oil-based paints.This so-called "drying" (actually a chemical reaction that produces an organic plastic) occurs through free-radical chemical crosslinking of the oils.

CaH 2 is thus used as a drying agent, i.e. a desiccant. [2] CaH 2 is a saline hydride, meaning that its structure is salt-like. The alkali metals and the alkaline earth metals heavier than beryllium all form saline hydrides. A well-known example is sodium hydride, which crystallizes in the NaCl motif. These species are insoluble in all solvents ...
Organic solutions can be dried using a range of drying agents. Typically following a workup the organic extract is dried using magnesium sulfate or a similar drying agent to remove most remaining water. [5] Anhydrous acetic acid is known as glacial acetic acid.
A drying oil is an oil that hardens to a tough, solid film after a period of exposure to air, at room temperature. The oil hardens through a chemical reaction in which the components crosslink (and hence polymerize) by the action of oxygen (not through the evaporation of water or other solvents).
Vacuum microwave drying is used for the US Army's experimental Close Combat Assault Ration. [3] Freeze drying or lyophilization is a drying method where the solvent is frozen prior to drying and is then sublimed, i.e., passed to the gas phase directly from the solid phase, below the melting point of the solvent. It is increasingly applied to ...
