1,3-бутадиен диэпоксид химические свойства, назначение, производство
Химические свойства
clear colorless to very slightly yellow liquid
Использование
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).
Методы производства
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.
Общее описание
Colorless liquid. Used in curing polymers; crosslinking textile fibers and to prevent spoilage.
Реакции воздуха и воды
Highly Flammable
Профиль реактивности
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.
Опасность
Probable carcinogen; neoplastigen; tumorigenic; poison; mutagen.
Угроза здоровью
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.
Пожароопасность
When heated to decomposition 1,3-BUTADIENE DIEPOXIDE emits acrid smoke and irritating fumes.
Профиль безопасности
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
Канцерогенность
Diepoxybutane is reasonably anticipated to be a human carcinogenbased on sufficient evidence of carcinogenicity from studies in experimental animals.
