Canisters are commonly filled with silica gel and other molecular sieves as desiccants in drug containers to keep contents dry Silica gel in a sachet or porous packet. A desiccant is a hygroscopic substance that is used to induce or sustain a state of dryness (desiccation) in its vicinity; it is the opposite of a humectant.
A desiccator is a heavy glass or plastic container, now somewhat antiquated, used in practical chemistry for drying or keeping small amounts of materials very dry. The material is placed on a shelf, and a drying agent or desiccant, such as dry silica gel or anhydrous sodium hydroxide, is placed below the shelf.
Silica gel's high specific surface area—around 750–800 m 2 /g (230,000–240,000 sq ft/oz) [6] —allows it to adsorb water readily, making it useful as a desiccant (drying agent). Silica gel is often described as "absorbing" moisture, which may be appropriate when the gel's microscopic structure is ignored, as in silica gel packs or other ...
Drying agent may refer to: Desiccant, which absorbs water or moisture from its vicinity; Oil drying agent, which speed up the hardening of oils, often used in painting
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.
Generally considered a universal drying agent in polar and nonpolar media; [12] separation of natural gas and alkenes, adsorption of water in non-nitrogen sensitive polyurethane: 5A-DW: 5: 0.45–0.50: 21–22: 0.3–0.6: Degreasing and pour point depression of aviation kerosene and diesel, and alkenes separation 5A small oxygen-enriched: 5: 0 ...
Not only is it a bad idea to double up the loads in the dryer after washing separately (thus, potentially overfilling your machine), but a few things can go wrong if you throw them all together.
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 ...
