Diethylene Glycol Methyl Ethyl Etheris an excellent reagent for converting compatible carboxylic acids to ethyl esters. Such carboxylic acids, refluxed neat in excess TEOF until low-boilers cease evolution, are quantitatively converted to the ethyl esters, without need for extraneous catalysis. Alternatively, added to ordinary esterifications using catalytic acid and ethanol, TEOF helps drive esterification to completion by converting the byproduct water formed to ethanol and ethyl formate. Diethylene Glycol Methyl Ethyl Etherare organic compounds in which an oxygen atom is connected to two carbon groups.  Unlike alcohols, ethers are fairly unreactive (except towards combustion). 


They are very common organic solvents, and some ethers also make good anesthetics. Simple ethers are named by naming the alkyl groups in alphabetical order and adding the word "ether" to the end.

 In more complicated ethers, the ether group is named as an alkoxy substituent, in which the "yl" ending of alkyl groups is replaced by "oxy."  For example, a methyl group attached to an oxygen, OCH3, is named as a methoxy group.  In cyclic ethers, the prefix oxa- is used to indicate replacement of a carbon by an oxygen. Since ethers do not have a hydrogen connected to the oxygen atoms, they are not capable of forming hydrogen bonds to each other.  

Thus, their boiling points are similar to those of alkanes of comparable molecular mass.  For example, propane, dimethyl ether, and ethanol have very similar molecular masses, but drastically different boiling points:

Glycol ethers are a group of solvents based on alkyl ethers of ethylene glycol or propylene glycol commonly used in paints and cleaners. These solvents typically have a higher boiling point, together with the favorable solvent properties of lower-molecular weight ethers and alcohols.  Glycol ethers are either "e-series" or "p-series" glycol ethers, depending on whether they are made from ethylene oxide or propylene oxide, respectively. Typically, e-series glycol ethers are found in pharmaceuticals, sunscreens, cosmetics, inks, dyes and water-based paints, while p-series glycol ethers are used in degreasers, cleaners, aerosol paints and adhesives. Both E-series glycol ethers and P-series glycol ethers can be used as intermediates that undergo further chemical reactions, producing glycol diethers and glycol ether acetates. P-series glycol ethers are marketed as having lower toxicity than the E-series. Most glycol ethers are water-soluble, biodegradable and only a few are considered toxic.

The ‘Diethylene Glycol Methyl Ethyl Ethers’ are a broad family of solvents and hydraulic fluids produced through the reaction of ethylene oxide and a monoalcohol (Bingham et al., 2001). In typical commercially available products, the alcohol can be methanol, ethanol, n- or isopropanol, n-butanol or n-hexanol. The number of ethylene oxide units in a single molecule can also vary, even to produce polymeric molecules, but a more typical level for commercial use is 1–4 (De Kettenis, 2005; ECETOC, 2005; OSPA, 2018). The generic formula can be expressed as: CnH2n+1(OCH2CH2)mOH where n is typically 1–6 and m is typically up . In addition to aliphatic alcohols, phenol may also be used as the alcohol. Finally, the terminal hydroxyl group of an ethylene glycol ether may in turn, under the right reaction conditions, react with another alcohol molecule to produce a dialkoxy molecule (often referred to as a ‘glyme’). Diethylene Glycol Methyl Ethyl Etheris derived as a co-product with ethylene glycol and triethylene glycol.


The industry generally operates to maximize MEG production. Ethylene glycol is by far the largest volume of the glycol products in a variety of applications. Availability of Diethylene Glycol Methyl Ethyl Etherwill depend on demand for derivatives of the primary product, ethylene glycol, rather than on Diethylene Glycol Methyl Ethyl Ethermarket requirements. Triethylene glycol, HO(C2H4O)3H, is a colourless, odourless, non-volatile, and hygroscopic liquid.

Diethylene Glycol Methyl Ethyl Etheris characterised by two hydroxyl groups along with two ether linkages, which contribute to its high water solubility, hygroscopicity, solvent properties and reactivity with many organic compounds.

TEG is displacing Diethylene Glycol Methyl Ethyl Etherin many of these applications on account of its lower toxicity. Diethylene Glycol Methyl Ethyl Etherfinds use as a vinyl plasticizer, as an intermediate in the manufacture of polyester resins and polyols, and as a solvent in many miscellaneous applications.

Diethylene Glycol Methyl Ethyl Etheris derived as a coproduct in the manufacture of ethylene glycol from ethylene oxide, and from "on-purpose" Diethylene Glycol Methyl Ethyl Etherproduction using Diethylene Glycol Monoethyl Ether. Some capacities are based on total capacity for ethylene glycols.

Diethylene Glycol Methyl Ethyl Etheras dehumidifiers and, when volatilized, as an air disinfectant for bacteria and virus control.

Diethylene Glycol Monoethyl Ether, having high boiling point and affinity for water, are employed as liquid desiccant for the dehydration of natural gas. The dehydration means the removal of water vapor in refinery tower so that dry hydrocarbon gases can exit from the top of the tower. There are wide range of glycol ethers which have bifunctional nature of ether and alcohol. cellosolves are monoether derivatives of ethylene glycol. They are excellent solvents, having solvent properties of both ethers and alcohols.
