  2. Hydrate - Wikipedia

    en.wikipedia.org/wiki/Hydrate

    Protein crystals commonly have as much as 50% water content. Molecules are also labeled as hydrates for historical reasons not covered above. Glucose, C 6 H 12 O 6, was originally thought of as C 6 (H 2 O) 6 and described as a carbohydrate. Hydrate formation is common for active ingredients. Many manufacturing processes provide an opportunity ...

  4. Clathrate hydrate - Wikipedia

    en.wikipedia.org/wiki/Clathrate_hydrate

    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 ...

  5. Mineral hydration - Wikipedia

    en.wikipedia.org/wiki/Mineral_hydration

    There are two main ways in which minerals hydrate. One is conversion of an oxide to a double hydroxide , as with the hydration of calcium oxide —CaO—to calcium hydroxide —Ca(OH) 2 . The other is with the incorporation of water molecules directly into the crystalline structure of a new mineral, [ 1 ] as with the hydration of feldspars to ...

  6. Methane clathrate - Wikipedia

    en.wikipedia.org/wiki/Methane_clathrate

    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.

  7. Nitrogen clathrate - Wikipedia

    en.wikipedia.org/wiki/Nitrogen_clathrate

    The SH unit cell contains 34 water molecules, 20 small cavities (5 12), 20 medium cavities (4 3 5 6 6 3) and 36 large cavities (5 12 6 8). [1] At still higher pressures a tetragonal form (termed ST) (4 2 5 8 6 4) exists. [1] At even higher pressures a phase called a filled ice structure (FIS) is formed. This has alternate layers of water and ...

    en.wikipedia.org/wiki/Γ-Cyclodextrin

    γ-Cyclodextrin exists as a white (colorless) powder or crystals. The density of its hydrate crystal (γCD·14H 2 O) is 1.41 g/cm 3 . γ-Cyclodextrin is well soluble in water and dimethyl sulfoxide , poorly soluble in methanol .
