Азодикарбонамид

Химические свойства

orange crystalline powder

Использование

Azodicarbonamide is a dough conditioner that exists as a yellow to orange-red crystalline powder practically insoluble in water. it is used in aging and bleaching cereal flour to produce a more manage- able dough and a lighter, more voluminous loaf of bread. it is used in bread flours and bread as a dough conditioner. it can be used with the oxidizing agent potassium bromate. a typical use level is less than 45 ppm.

Общее описание

A yellow to orange powder. Insoluble in water and common solvents. Soluble in dimethyl sulfoxide. Nontoxic.

Реакции воздуха и воды

Highly flammable. Water insoluble. Dust may form an explosive mixture in air.

Профиль реактивности

Azodicarbonamide is easily ignited and burns rapidly. Confined samples show a high rate of pressure rise during thermal decomposition, which produces carbon monoxide and nitrogen. Sensitive to temperatures exceeding 122°F. May be sensitive to exposure to light. Stable in bulk when stored for two weeks at temperatures up to 140°F. Slightly unstable in water suspension (showed1.3% decomposition at 2 mg/mL over a two-week period at room temperature in the light but no decomposition at 41°F over a two-week period in the dark . Reacts with hot water to give nitrogen, carbon monoxide, and ammonia [Hawley]. Decomposes in hot hydrochloric acid. Incompatible with strong acids and bases, and with compounds of metals.

Угроза здоровью

Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control may cause pollution.

Пожароопасность

Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. May burn violently. Decomposition may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air.

Профиль безопасности

Flammable solid. When heated to decomposition it emits toxic fumes of NOx.
