Diglyme, or bis(2-methoxyethyl) ether, is an organic compound with the chemical formula (CH 3 OCH 2 CH 2) 2 O. It is a colorless liquid with a slight ether-like odor. It is a solvent with a high boiling point. It is the dimethyl ether of diethylene glycol. The name diglyme is a portmanteau of diglycol methyl ether. It is miscible with water as ...
[2] Enzymes that catalyze dehydrogenation are called dehydrogenases . In metal manufacturing and repairs, dehydrogenation is a thermal treatment which consists in removing the hydrogen absorbed by an object during an electrochemical or chemical process, performed in a specific oven at a temperature of 180–200 °C (360–390 °F) for a minimum ...
In organic chemistry, some dehydration reactions are subject to unfavorable but fast equilibria. One example is the formation of dioxolanes from aldehydes: [9] RCHO + (CH 2 OH) 2 RCH(OCH 2) 2 + H 2 O. Such unfavorable reactions proceed when water is removed by azeotropic distillation.
Organic acid anhydrides often form when one equivalent of water is removed from two equivalents of an organic acid in a dehydration reaction. In inorganic chemistry, an acid anhydride refers to an acidic oxide, an oxide that reacts with water to form an oxyacid (an inorganic acid that contains oxygen or carbonic acid), or with a base to form a ...
Alkenes can be made from alcohols by dehydration. This conversion, among others, is used in converting biomass to liquid fuels. [2] The conversion of ethanol to ethylene is a fundamental example: [3] [4] CH 3 CH 2 OH → H 2 C=CH 2 + H 2 O. The reaction is accelerated by acid catalysts such as sulfuric acid and certain zeolites.
Laundry hung on a clothes line in a drying room (dehumidifier in the background and duct for ventilation in the ceiling) Drying is a mass transfer process consisting of the removal of water or another solvent [1] by evaporation from a solid, semi-solid or liquid. This process is often used as a final production step before selling or packaging ...

Dimethylacetamide (DMAc or DMA) is the organic compound with the formula CH 3 C(O)N(CH 3) 2. This colorless, water-miscible, high-boiling liquid is commonly used as a polar solvent in organic synthesis. DMA is miscible with most other solvents, although it is poorly soluble in aliphatic hydrocarbons.
