ГЛИКОЛНИТРИЛ химические свойства, назначение, производство
Химические свойства
light yellow liquid (typically available as a concentrated. Glycolonitrile [107-16-4], hydroxyacetonitrile, formaldehyde cyanohydrin, HOCH2CN, Mr
57.05, bp 183℃ (slight decomp.), d154 1.104, n20D1.4117. Anhydrous glycolonitrile is a colorless
liquid which is miscible with water, ethanol and
diethyl ether.
Использование
Solvent and organic intermediate.
Методы производства
Glycolonitrile is the result of reaction between formaldehyde
and aqueous sodium cyanide in the presence of mineral acid.
Общее описание
Odorless colorless oil with a sweetish taste. Used in the manufacture of intermediates in pharmaceutical production, as a component of synthetic resins, as a chemical intermediate for organic compounds, and as a solvent.
Реакции воздуха и воды
Water soluble.
Профиль реактивности
Glycolonitrile may undergo spontaneous and violent decomposition. Traces of alkali (base) promote violent polymerization [Lewis].
Опасность
Toxic by ingestion, inhalation, and skin
absorption.
Угроза здоровью
Extremely toxic, exposure by any route should be avoided; may have fatal consequences; death from asphyxiation may occur similar to that resulting from hydrogen cyanide.
Пожароопасность
Moderate explosion hazard when exposed to heat or by spontaneous chemical reaction in the presence of alkalies if uninhibited. When heated to decomposition, Glycolonitrile emits highly toxic fumes of cyanide and nitrogen oxides. Unstable, may explode on standing. Hazardous polymerization may occur. avoid the presence of alkalis, and exposure to heat.
Возможный контакт
Formaldehyde cyanohydrin is used in
the manufacture of intermediates in pharmaceutical produc tion and as a component of synthetic resins as a chemical
intermediate for organic compounds, and as a solvent.

Несовместимости
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, and exposure to heat.
Unless stabilized with a weak acid solution, traces of alka lis may cause violent polymerization.
