글루탈알데히드 C화학적 특성, 용도, 생산

물성

글루 타르 알데히드 (111-30-8)는 광범위한 스펙트럼, 고효율, 저 독성, 작은 금속 부식, 유기 물질에 대한 작은 영향, 우수한 안정성 등을 갖춘 효율적인 소독제입니다. 그것은 의료 기기 및 젖은 볼거리 열을위한 정밀 기기의 살균 및 멸균에 적합합니다. 그것의 살균 농도는 2 %, 도시는 글루 타 알데히드를 주로 판매합니다 : 2 % 알칼리성 글루 타르 알데히드와 2 %는 글루 타르 알데히드를 강화합니다. 알칼리성 글루 타르 알데히드는 일반적으로 의료 장비 살균에 사용되기 전에 중탄산 나트륨 적절한 양에 추가되어야합니다, 균등하게, 정적 1 시간, ph 값의 결정 동요. ph가 7.5-8.5 일 때, 글루 타르 알데히드는 가장 강력한 살균 효과를 갖는다.

용도

글루 타 알데히드 살균 (111-30-8)은 그 단량체의 역할이며, 6의 용액 ph는 이들 단량체가 중합의 추세를 가지며,이 중합의 ph가 증가하면 용액이 나타날 수있다 침전물, 중합체의 형성은 살균 효과를 잃을 것이다. 따라서 알칼리성 글루 타르 알데히드는 상대적으로 불안정한 살균제이며, 2 % 가량의 산성 글루 타르 알데히드는 글루 타 알데히드의 살균 효과를 향상시키는 폴리 옥시 에틸렌 지방 알콜 에테르와 함께 강화제이다. 그 ph는 5 미만, 박테리아의 죽이는 효과 알칼리 글루 타르 알데히드보다 약하지만 바이러스의 불활 화 알칼리성 글루 타르 알데히드보다 강하다, 안정성은 알칼리성 글루 타르 알데히드보다 나은 있으며, 28 일 연속 사용할 수 있습니다.

개요

Glutaraldehyde is a well-known sensitizer among cleaners and health workers. It is also found in X-ray developers products.

화학적 성질

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.

용도

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.

정의

ChEBI: A dialdehyde comprised of pentane with aldehyde functions at C-1 and C-5.

일반 설명

Light yellow liquid. Mixes with water.

공기와 물의 반응

Polymerizes in the presence of water.

반응 프로필

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.

건강위험

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.

화재위험

Literature sources indicate that Pentanedial is nonflammable.

색상 색인 번호

Glutaraldehyde is a well-know sensitizer in cleaners and health workers. It can also be found in X-ray developers or in cosmetics.

Safety Profile

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.

잠재적 노출

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.

운송 방법

UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

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.]

비 호환성

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.

폐기물 처리

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.
