The largest use of dimethyl ether is as the feedstock for the production of the methylating agent, dimethyl sulfate, which entails its reaction with sulfur trioxide: CH 3 OCH 3 + SO 3 → (CH 3) 2 SO 4. Dimethyl ether can also be converted into acetic acid using carbonylation technology related to the Monsanto acetic acid process: [6]
Drinking ether is challenging as it boils below body temperature and is not miscible with water, requiring precautions: . There is an art in swallowing the ether. The drinker first washes out his mouth with water “to cool it;” next he swallows a little water to cool his throat; then he tosses down the glass of ether; finally, he closes in with another draught of water to keep the ether ...
2,5-Dimethoxy-p-cymene, or thymohydroquinone dimethyl ether, is a phytochemical found in the essential oils of plants within the family Asteraceae. These essential oils, which contain the compound as a major component of the oil, have antifungal , [ 1 ] antibacterial , [ 2 ] and insecticidal [ 3 ] properties.
Dimethoxyethane, also known as glyme, monoglyme, dimethyl glycol, ethylene glycol dimethyl ether, dimethyl cellosolve, and DME, is a colorless, aprotic, and liquid ether that is used as a solvent, especially in batteries. [2] Dimethoxyethane is miscible with water.
Dimethyl ethers of PEG are the key ingredient of Selexol, a solvent used by coal-burning, integrated gasification combined cycle (IGCC) power plants to remove carbon dioxide and hydrogen sulfide from the syngas stream. PEG has been used as the gate insulator in an electric double-layer transistor to induce superconductivity in an insulator. [37]
For spot-cooling of electronic components during troubleshooting, dimethyl ether or tetrafluoroethane may be used. [2] Freeze sprays are also used to contract metal for assembly or disassembly of interference fit parts. [citation needed] The extreme temperature can cause viscoelastic materials to change to glass phase.
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 ...
Based on the efficacy and safety of this formulation, and evidence that dimethyl fumarate was the main active component, an oral formulation of dimethyl fumarate was developed by Almirall. [19] This oral formulation, under the brand name Skilarence, was approved by the European Medicines Agency (EMA) in June 2017, for the treatment of moderate ...
