Diethylene glycol monobutyl ether Usage And Synthesis
Chemical PropertiesDiethylene glycol monobutyl ether is a colorless, high-boiling liquid with a mild odour. It is miscible in proportions with water, alcohol (methanol), ketones (acetone), ethers (ethyl ether), aromatic hydrocarbons (benzene), paraffinic hydrocarbons (n-heptane), and halogenated hydrocarbons (carbon tetrachloride). As it is an ether-alcohol type compound it possesses solvent action for many substances such as oils, dyes, gums, and natural and synthetic resins. It is used as a high-boiling solvent in nitrocellulose lacquers and other synthetic coatings, baking lacquers, flash-dry printing inks, and dye bath.
UsesDiethylene glycol monobutyl ether(DGBE) is widely used as a solvent for cellulose ester, lacquers, varnishes, cleaners, detergents, dyes, ink, and paint industries. it is also used as an intermediate for plasticizers and a diluent for hydraulic brake fluids, in addition to the production of piperonyl butoxy compounds. In France, its use in the cosmetics industry is permissible, wherein it is used as a solvent in hair dyes with a maximum concentration of 9%.
ApplicationDiethylene glycol mono-n-butyl ether has a wide variety of applications in Chiral chemistry and green chemistry. It is also used in cosmetics. It is used as diluents and leveling agents in the manufacture of paints and in baking. It is also used in the manufacture of nitrocellulose. In brake fluid, it is used as an additive. It is used in the printing industry due to its slow evaporation rate. It is also used as a fixative for perfumes and antiseptics. It is used as an additive to prevent ice buildup in jet fuel.
PreparationDiethylene glycol monobutyl ether is prepared by co-heating ethylene oxide and ethylene glycol butyl ether under pressure.
General DescriptionDiethylene glycol monobutyl ether is a colorless liquid with a mild pleasant odor. Mixes with water. (USCG, 1999)
Air & Water ReactionsOxidizes readily in air to form unstable peroxides that may explode spontaneously [Bretherick, 1979 p.151-154, 164]. Water soluble.
Reactivity ProfileButyldiglycol is a ether-alcohol derivative. The ether being relatively unreactive. Flammable and/or toxic gases are generated by the combination of alcohols with alkali metals, nitrides, and strong reducing agents. They react with oxoacids and carboxylic acids to form esters plus water. Oxidizing agents convert alcohols to aldehydes or ketones. Alcohols exhibit both weak acid and weak base behavior. They may initiate the polymerization of isocyanates and epoxides.
Health HazardDiethylene glycol monobutyl ether(DGBE) is an eye irritant. It showed low toxicity in test species.Toxic symptoms are similar to those ofother glycol ethers containing two etherealoxygen atoms. Inhalation for brief periods has no significant effect. Contact with liquid causes moderate irritation of eyes and corneal injury. Prolonged contact with skin causes only minor irritation. The high dosescaused pulmonary congestion. No renaldamage was reported. There is no reporton teratogenicity of this compound.
Fire HazardButyldiglycol is combustible.
Flammability and ExplosibilityNonflammable
Contact allergensThis organic solvent belongs to the carbitols group and is included in waterbased liquids such as paints, surface cleaners, polishes, and disinfectants. It is considered to be an exceptional allergen.
Safety ProfileModerately toxic by ingestion and intraperitoneal routes. Mddly toxic by skin contact. A severe eye irritant. Combustible when exposed to heat or flame; can react with oxidizing materials. To fight fire, use alcohol foam, CO2, or dry chemical. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
Purification MethodsDry the ether with anhydrous K2CO3 or CaSO4, filter and fractionally distil it. Peroxides can be removed by refluxing with stannous chloride or a mixture of FeSO4 and KHSO4 (or, less completely, by filtration under slight pressure through a column of activated alumina). [Beilstein 1 IV 2394.]
Waste DisposalDGBE is mixed with a combustible solventand burned in a chemical incinerator. Smallamounts may be disposed down the drainwith large amounts of water.
