용도

니트로디글리콜의 원료.

용도

에틸렌옥사이드와 물 또는 에틸렌글리콜을 가열하든가, 에틸렌클로로히드린 또는 브로모히드린과 글리콜을 120℃에서 반응시킨다.

화학적 성질

Diethylene glycol is a clear colorless, odorless and stable oily liquid. It is also slightly viscous, noncorrosive and nonvolatile. Because of its ether and alcohol group, diethylene glycol exhibits chemical properties characteristic of both primary alcohols and ethers. Its boiling point is considerably higher than that of ethylene glycol, and its solvent is greater. Diethylene glycol is miscible with water, ethers, lower aliphatic alcohols, aldehydes and ketones and is partially soluble in benzene, carbon tetrachloride, monobenzene, orthodichlorobenzene and toluene. It dissolves many dyes, resins, oils, nitrocellulose and many organic substances. Because of its solvent power, low volatility and hygroscopicity, it is used in textile lubricants, cutting oils, dry cleaning soap, printing inks, steam-set inks, and nongrain wood stains. In the textile industry diethylene glycol is used as a conditioning agent for wool, rayon, and cotton. As a solvent for dyes it makes a valuable assistant in dyeing and printing. The high hygroscopicity of diethylene glycol makes it an efficient softening agent for tobacco, paper, synthetic sponges, glues and casein. Diethylene glycol is especially useful in the dehydration of natural gas. A mixture of diethylene glycol and monoethanolamine will remove moisture, hydrogen sulfide and carbon dioxide from natural gas.

용도

In antifreeze solution for sprinkler systems, water seals for gas tanks, etc. (water with 40% diethylene glycol freezes at -18°; with 50% at -28°); as lubricating and finishing agent for wool, worsted, cotton, rayon, and silk; as solvent for vat dyes; in composition corks, glues, gelatin, casein, and pastes to prevent drying out.

용도

Diethylene glycol is a colorless, odorless, clear liquid. It is miscible with water in any ratio. It has many industrial uses. It is a component of antifreeze, brake fluids, cosmetics, inks, and drying agents, and it is used as a plasticizer.

일반 설명

A colorless liquid. Denser than water. Contact may slightly irritate skin, eyes and mucous membranes. May be slightly toxic by ingestion. Used to make other chemicals.

공기와 물의 반응

Slightly soluble in water.

반응 프로필

Diethylene glycol is incompatible with strong oxidizing agents. Diethylene glycol is also incompatible with strong bases. Diethylene glycol can react with sulfuric acid and other dehydrating agents, nitric acid, oxygen, hydrogen peroxide, perchloric acid and strong acids. Mixtures with sodium hydroxide decompose exothermically when heated to 446° F.

건강위험

Ingestion of large amounts may cause degeneration of kidney and liver and cause death. Liquid may cause slight skin irritation.

화재위험

Diethylene glycol is combustible.

화재위험

Flash Point (°F): 255 ℃; Flammable Limits in Air (%): 1.6-10.8;Fire Extinguishing Agents: Alcohol foam, carbon dioxide, dry chemical; Fire Extinguishing Agents Not To Be Used: Water or foam may cause frothing; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 444; Electrical Hazard: Not pertinent; Burning Rate: 1.5 mm/min.

화학 반응

Reactivity with Water No reaction; Reactivity with Common Materials: No reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pert.

Toxicology

The toxicity of diethylene glycol is similar to ethylene glycol and clearly is a CNS depressant. It has a low inhalation hazard because of its low vapor pressure; however, inhalation of the mist or aerosol is to be avoided. Workplace levels for vapors and aerosols cannot exceed 50 ppm. In case of accidental release of diethylene glycol, use of a full-face positive air pressure respirator is recommended. Even though the toxicokinetics in humans is not completely understood, its toxic nature is confirmed by animal studies. Several human cases were reported in the medical literature. Several children in Haiti died in 1995 and 1996 following the consumption of medication containing diethylene glycol. Similar other cases in children were reported in other countries as well. A 24-year-old man developed encephalopathy and rapidly became quadriplegic following ingestion of a solution containing diethylene glycol . Thus, the toxicity of diethylene glycol is well established.

Safety Profile

Moderately toxic to humans by ingestion. Poison experimentally by inhalation. Moderately toxic by ingestion and intravenous routes. Questionable carcinogen with experimental carcinogenic,tumorigenic, and teratogenic data. An eye and human skin irritant. Combustible when exposed to heat or flame; can react with oxidning materials. To fight fire, use alcohol foam, water, Con, dry chemical. Mixtures with sodium hydroxide decompose exothermically when heated to 230℃ and release explosive hydrogen gas. When heated to decomposition it emits acrid smoke and irritating fumes. See also GLYCOL ETHERS.
