ACS, ETHER, 99.9%, HPLC GRADE, INHIBITOR-FREE (FOR EUROPEAN USE ONLY), Diethyl ether, anhydrous, A.C.S. Dimethyl ether (DME) is the simplest ether, consisting of two methyl groups bonded to a central oxygen atom, as expressed by its chemical formula CH3-O-CH3, Figure 1. Dimethyl ether (typically abbreviated as DME), also known as methoxymethane, wood ether, dimethyl oxide or methyl ether, is the simplest ether. Polyoxymethylene dimethyl ethers—abbreviated OME, PODE or POMDME—are a class of DME derivatives that include several oxymethylene (-O-CH2-) groups in the molecule, with a chemical formula CH3(-O-CH2)n-O-CH3 (Figure 2). The US Department of Energy’s Alternative Fuels Data Center. Structure, properties, spectra, suppliers and links for: dimethyl ether, 115-10-6, (CH3)2O, CH3-O-CH3. It is shipped as a liquefied gas under its vapor pressure. OME compunds with n of 3-4 were tested as diesel engine fuels . property mean. ACS, REAG. Take 1ml of ether and 2ml of 0.9% sodium chloride solution, mix them and then inject from the arm vein. Furthermore, DME fuel lacks an established supply and fueling infrastructure. DME can be made from a range of options that can make it extremely competitive if not significantly more affordable than traditional diesel. Similar Compounds. DME has been used for decades as an energy source in China, Japan, Korea, Egypt, and Brazil, and it can be produced domestically from a variety of feedstocks, including biogas from organic waste produced in cities or by agricultural operations, as well as natural gas. The chemical reaction is as follows. Its high cetane value (55-60) and quiet combustion, as well as its inexpensive fueling system, make it an excellent, inexpensive diesel alternative that will meet strict emissions standards. In an alternative utilization method, DME can be blended with propane for use in spark-ignited LPG engines. Dimethyl ether (DME, also known as methoxymethane) is the organic compound with the formula CH3OCH3, simplified to C2H6O. Dimethyl Ether: Production Chronic exposure to diethyl ether vapor may lead to loss of appetite, exhaustion, drowsiness, dizziness, and other central nervous system effects. Dimethyl ether is intended for use as an extraction solvent in the processing of various food . DME has also been issued specifications by ASTM International and the International Organization for Standardization (ISO). It is used as a precursor for the preparation of important useful organic compounds. The maximum allowable concentration in the workplace is 400×10-6. Ethers such as diethyl ether dissolve a wide variety of organic compounds of polar and non-polar origin.

Note: Cheméo is only … It can be easily handled and stored as liquefied gas, … Diethyl ether is highly flame retardant and can form explosive mixtures of air / vapour. IS O, REAG. Breathing Diethyl Ether can cause drowsiness, arousal, dizziness, vomiting, irregular breathing, and saliva. reagent, >=99.0% (Contains BHT as stabilizer), DIETHYL ETHER EXTRA PUR, DAB, PH.

Patients with potential heart failure are banned. High exposure may result in unconsciousness or even death.
In diethyl ether, non-polar compounds are usually more soluble than alcohols because ethers do not have a hydrogen bonding network that needs to be broken up to dissolve the solute. Dimethyl isosorbide. Potential future uses of DME include an alternative automotive fuel, a substitute for other fuels in power generation and in the household and a source of hydrogen for fuel cells . However, because it can be stored as a liquid under moderate pressure, it eliminates the need for the high-pressure containers used for CNG or cryogenics, as is the case with LNG. It is an isomer of ethanol.
