Ethylene Glycol Monobutyl Ether 111-76-2 | TCI America

Ethylene glycol is a colourless, odourless, involatile and hygroscopic liquid with a sweet taste. It is somewhat viscous liquid; miscible with water; boiling point 198 C, melting point 13 C; soluble in ethanol, acetone, acetic acid, glycerine, pyridine, aldehydes; slightly soluble in ether; insoluble in oil, fat, hydrocarbones.

Diethylene glycol (DEG) is derived as a co-product with ethylene glycol and triethylene glycol.

Triethylene glycol (TEG) is derived as a coproduct in the manufacture of ethylene glycol from ethylene oxide, and from "on-purpose" TEG production using diethylene glycol.


A synthetic method for oligo(ethylene glycol) toward 44-mer (FW = 1956.35) is described. Reiteration of Williamson's ether synthesis and hydrogenation to remove protecting benzyl group affords desired oligo(ethylene glycol) toward 44-mer in moderate yields. The advantages in this method are use of commercially easily available materials as starting materials and procedures avoiding difficulty in purification of the products as much as possible.

Polyethylene glycols and polypropylene glycols are sometimes called polyglycols which are derived by polymerization of ethylene oxide and propylene oxide respectively.


TCC’s Diethylene Glycol (DEG) is a straight-chain dihydric alcohol which is aliphatic terminated on both ends by a hydroxyl group. It is a clear, water-white, practically odorless, hygroscopic liquid at room temperature. DEG is a water-soluble liquid with a boiling point of 245 C. It is also soluble in many organic solvents.

Diethylene glycol is used as a dehydrating agent for natural gas, a raw material for the production of plasticizers and polyester resin, and a widely used solvent. It is also used as a humectant in the tobacco industry and in the treatment of corks, glue, paper and cellophane as well as in the synthesis of morpholine and 1,4-dioxane.

Any solid biomass including for example agricultural, city and industrial waste can be used to make synthesis gas using techniques similar to its production from . More recent developments includes a plant in the Netherlands, which is using liquid propane-1,2,3-triol (glycerol), a by-product from the production of , from animal fats and vegetable oils.

Another way to produce propene is via methanol (produced from biomass via synthesis gas), which is an example of the MTO (Methanol To Olefins) process. (Olefin is the older name for the homologous series, alkenes). Methanol can be converted into high purity ethene and propene via dimethyl ether (Figure 3, routes 10 and 9). Methanol vapour is passed over alumina at ca 600 K. An equilibrium mixture of methanol, dimethyl ether and steam is produced, containing about 25% methanol:
