有機合成原料。
化学的特性
clear colorless to very slightly yellow liquid
使用
Diepoxybutane has been used as a research chemical, as a chemical intermediate, as a curing agent for polymers, as a cross-linking agent for textile fabrics, and to prevent microbial spoilage (IARC 1976, HSDB 2009). It has also been used to synthesize erythritol and pharmaceuticals (HSDB 2009). Because of its cross-linking properties, diepoxybutane is used as a test agent in the diagnosis of Fanconi anemia, which is characterized by chromosomal instability (Auerbach et al. 1989).
調製方法
Diepoxybutane is prepared by chlorination of butadiene
followed by epoxidation with peracetic acid, with subsequent
hydrolysis of the epoxide group and final reepoxidation with
caustic.
一般的な説明
Colorless liquid. Used in curing polymers; crosslinking textile fibers and to prevent spoilage.
空気と水の反応
Highly Flammable
反応プロフィール
Epoxides, such as 1,3-BUTADIENE DIEPOXIDE, are highly reactive. They polymerize in the presence of catalysts or when heated. These polymerization reactions can be violent. Compounds in this group react with acids, bases, and oxidizing and reducing agents. They react, possibly violently with water in the presence of acid and other catalysts.
危険性
Probable carcinogen; neoplastigen; tumorigenic; poison; mutagen.
健康ハザード
Severe skin and eye irritant. Accidental minor exposure caused swelling of the eyelids, upper respiratory tract irritation and painful eye irritation 6 hours after exposure.NOTE: The dl- and meso-forms (CAS Registry Numbers 298-18-0 and 564-00-1, respectively) as well as the L(-) form (CAS Registry Number 30031-64-2) have all been determined to be positive animal carcinogens.
火災危険
When heated to decomposition 1,3-BUTADIENE DIEPOXIDE emits acrid smoke and irritating fumes.
安全性プロファイル
Confirmed carcinogen withexperimental tumorigenic data. Poison by ingestion,inhalation, skin contact, and intraperitoneal routes.Human mutation data reported. A severe skin and eyeirritant. When heated to decomposition it emits acridsmoke and irritat
発がん性
Diepoxybutane is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
