Clathrate hydrates (also known as gas hydrates, gas clathrates, etc.) are water ice with gas molecules trapped within; they are a form of clathrate. An important example is methane hydrate (also known as gas hydrate, methane clathrate, etc.). Nonpolar molecules such as methane can form clathrate hydrates with
Clathrate hydrate, which encaged CO 2 as guest molecule is termed as CO 2 hydrate. The term CO 2 hydrates are more commonly used these days with its relevance in anthropogenic CO 2 capture and sequestration. A nonstoichiometric compound, carbon dioxide hydrate, is composed of hydrogen-bonded water molecules arranged in ice-like frameworks that ...
In inorganic chemistry, mineral hydration is a reaction which adds water to the crystal structure of a mineral, usually creating a new mineral, commonly called a hydrate. In geological terms, the process of mineral hydration is known as retrograde alteration and is a process occurring in retrograde metamorphism.
Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
A salt with associated water of crystallization is known as a hydrate. The structure of hydrates can be quite elaborate, because of the existence of hydrogen bonds that define polymeric structures. [ 3 ] [ 4 ] Historically, the structures of many hydrates were unknown, and the dot in the formula of a hydrate was employed to specify the ...
Hydration may refer to: . Hydrate, a substance that contains water; Hydration enthalpy, energy released through hydrating a substance; Hydration reaction, a chemical addition reaction where a hydroxyl group and proton are added to a compound
Cryostasis utilizes clathrate-forming gases that penetrate and saturate the biological tissues causing clathrate hydrates formation (under specific pressure-temperature conditions) inside the cells and in the extracellular matrix. Clathrate hydrates are a class of solids in which gas molecules occupy "cages" made up of hydrogen-bonded water ...
Aldehydes and to some extent even ketones, hydrate to geminal diols. The reaction is especially dominant for formaldehyde, which, in the presence of water, exists significantly as dihydroxymethane. Conceptually similar reactions include hydroamination and hydroalkoxylation, which involve adding amines and alcohols to alkenes.
