Описание
Glutaraldehyde is a well-known sensitizer among cleaners and health workers. It is also found in X-ray developers products.Химические свойства
Glutaraldehyde is a colorless liquid with a pungent odor, which readily changes to a glossy polymer. The Odor Threshold is 0.04 ppm (NY) and 0.2 ppm (NJ). It is miscible in water and organic solvents. Glutaraldehyde may be incompatible with strong oxidizers and strong bases. It should be noted that alkaline solutions containing glutaraldehyde may react with alcohol, ketones, amines, hydrazines, and proteins.
Использование
Glutaraldehyde (Symbol GTA; glutaric dialdehyde, 1,5-pentanedial, glutaral) is commonly used in the medical industry in cold sterilization and in the X-ray development process. It can also be encountered in the leather industry as a tanning ingredient and in mortuary workers. There are no reports which indicate that glutaraldehyde is a naturally occurring compound. Cidex and Acusol, 2% buffered solutions, use this aldehyde as an active ingredient. Sodium bicarbonate is required to activate the solution, which then has a shelf life of 1–2 weeks. Despite health hazards involved with its use, glutaraldehyde is one of the most effective biocides used. It is particularly effective against bacteria and viruses, including the human immunodeficiency virus.Определение
ChEBI: A dialdehyde comprised of pentane with aldehyde functions at C-1 and C-5.Общее описание

GLUTARALDEHYDE may discolor on exposure to air. Pentanedial polymerizes on heating. Pentanedial is incompatible with strong oxidizing agents. Pentanedial polymerizes in the presence of water.Угроза здоровью
Glutaraldehyde is a strong irritant to the nose,eyes, and skin. In rabbits, 250 μg and 500 mg in 24 hours produced severe irritation in theeyes and skin, respectively. The corrosiveeffect on human skin of 6 mg over 3 dayswas severe. However, the acute toxicity ofglutaraldehyde by the oral and dermal routesis low to mild. Ohsumi and Kuroki (1988)determined that the symptoms of acute toxicityof this compound were less severethan those of formaldehyde. But the restraintof growth was more pronounced in micetreated with glutaraldehyde. An oral LD50value of 1300 mg/kg was reported for mice.Inhalation of this compound can cause upperrespiratory tract irritation, headache, and nervousness.Mice exposed at 33 ppm showedsymptoms of hepatitis.Пожароопасность
Literature sources indicate that Pentanedial is nonflammable.Контактные аллергены
Glutaraldehyde is a well-know sensitizer in cleaners and health workers. It can also be found in X-ray developers or in cosmetics.Профиль безопасности
Poison by ingestion, intravenous, and intraperitoneal routes. Moderately toxic by inhalation, skin contact, and subcutaneous routes. Experimental teratogenic and reproductive effects. A severe eye and human skin irritant. Mutation data reported. When heated to decomp osition it emits acrid smoke and irritating fumes. See also ALDEHYDES.Возможный контакт
Glutaraldehyde is used in leather tanning; in embalming fluids; as a germicide; as a cross-linking agent for protein and polyhydroxy materi als; as a fixative for tissues; and as an intermediate. Buffered solutions are used as antimicrobial agents in hospitals.Перевозки
UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.Методы очистки
Likely impurities are oxidation products-acids, semialdehydes and polymers. It can be purified by repeated washing with activated charcoal (Norit) followed by vacuum filtration, using 15-20g charcoal/100mL of glutaraldehyde solution. Distil it at 60-65o/15mm, discarding the first 5-10%, then dilute with an equal volume of freshly distilled water at 70-75o, using magnetic stirring under nitrogen. The solution is stored at low temperature (3-4o), in a tightly stoppered container, and protected from light. Standardise by titration with hydroxylamine. [Anderson J Histochem Cytochem 15 652 1967, Beilstein 1 IV 3659.]Несовместимости
Water contact forms a polymer solution. A strong reducing agent. Incompatible with strong acids; caustics, ammonia, amines, and strong oxidizers. Note: Alkaline solutions of glutaraldehyde (i.e., activated glutar aldehyde) react with alcohol, ketones, amines, hydrazines, and proteins.Утилизация отходов
Dissolve or mix the material with a combustible solvent and burn in a chemical incinera tor equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.Глутаральдегид запасные части и сырье
