2-Oxetanone

베타-프로피올락톤 C화학적 특성, 용도, 생산

화학적 성질

Colorless to light yellow liqui

화학적 성질

β-Propiolactone is a colorless liquid which slowly hydrolyzes to hydracrylic acid and must be cooled to remain stable.

용도

Reacts with bacteriphage DNA causing inactivation, repair and recombination

용도

antiandrogen

용도

Versatile intermediate in organic synthesis.

상표명

Betaprone (Forest).

일반 설명

A colorless liquid with a slightly sweetish, pungent odor. Used as an intermediate in organic synthesis; disinfectant, sterilant for blood plasma, tissue grafts, vaccines, enzymes and surgical instruments.

공기와 물의 반응

Slow reaction with water to form beta- hydroxypropionic acid.

반응 프로필

2-Oxetanone is an ester. Esters react with acids to liberate heat along with alcohols and acids. Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. Heat is also generated by the interaction of esters with caustic solutions. Flammable hydrogen is generated by mixing esters with alkali metals and hydrides. 2-Oxetanone may be incompatible with alkalis.

위험도

Strong skin and upper respiratory tract irri- tant, skin cancer. Possible carcinogen. Worker expo- sure should be minimized.

건강위험

The toxicity potential of 2-Oxetanone via inhalation or ingestion is high; may cause death or permanent injury after very short exposures to small quantities. It is a carcinogen.

화재위험

Containers may explode. When heated to decomposition, 2-Oxetanone emits acrid smoke and fumes. Stable when stored at 41F. Avoid storing in areas of exposure to the direct rays of the sun and in areas of high fire hazard. Tends to polymerize on storage. Avoid elevated temperatures.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by inhalation. Moderately toxic by intraperitoneal route. An initiator. Human mutation data reported. When heated to decomposition it emits acrid smoke and irritating fumes.

잠재적 노출

β-Propiolactone is used as a chemical intermediate in synthesis of acrylic acid and esters, acrylate plastics; as a vapor sterilizing agent; phase disinfectant; and a viricidal agent.

Carcinogenicity

β-Propiolactone is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.

환경귀착

Chemical/Physical. Slowly hydrolyzes to hydracrylic acid (Windholz et al., 1983). In a reactor heated to 250 °C and a pressure of 12 mmHg, β-propiolactone decomposed to give equal amounts of ethylene and carbon dioxide (James and Wellington, 1969).

운송 방법

UN3382 Toxic by inhalation liquid, n.o.s. with an LC 50 ≤1000 mL/m 3 and saturated vapor concentration ≥10 LC 50 , Hazard class: 6.1; Labels: 6.1 Technical Name Required, Inhalation Hazard Zone B. UN2810 Toxic liquids, organic, n.o.s., Hazard Class: 6.1; Labels: 6.1-Poisonous materials, Technical Name Required.

Purification Methods

Fractionally distil the lactone from sodium under reduced pressure. It gives an acidic solution in H2O. It irritates the skin and is a possib

비 호환성

Reacts with water, causing decomposi- tion and forming 3-hydroxypropionic acid (CAS: 503-66- 3), an irritant. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explo- sions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Incompatible with acet- ates, halogens, thiocyanates, thiosulfates, strong oxidizers; strong bases. Forms explosive mixture with air above 75℃. May polymerize upon storage or due to warming. Stable if kept under refrigeration @ 5 to 10 ℃/40 to 50 ℃.

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.
