frequently used as a disinfectant or a bleaching agent Sodium nitrite: used to convert amines into diazo compounds Sulfuric acid: strong mineral acid; applications include its use as a dehydrating agent in many chemical reactions, sulfonation, the purification of hydrocarbons, and the production of phosphoric acid tert-Butyl hydroperoxide
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.
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 ...
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.
Calcium hydride is the chemical compound with the formula CaH 2, an alkaline earth hydride. This grey powder (white if pure, which is rare) reacts vigorously with water, liberating hydrogen gas. 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 ...
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
Phosphorus pentoxide is a potent dehydrating agent as indicated by the exothermic nature of its hydrolysis producing phosphoric acid: P 4 O 10 + 6 H 2 O → 4 H 3 PO 4 (–177 kJ) However, its utility for drying is limited somewhat by its tendency to form a protective viscous coating that inhibits further dehydration by unspent material.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
