4-Нитробензилхлорид химические свойства, назначение, производство
Химические свойства
white to light yellow crystal powde
Использование
4-Nitrobenzyl chloride was used to prepare unsymmetrically N,N′-bis(substituted) 4,13-diaza-18-crown-6-ether derivatives.
Методы производства
Chlorination of 4-nitrotoluene at 190 ℃ without catalyst gives 4-Nitrobenzyl chloride. The alternative process of nitration of benzylchloride coproduces 2-nitrobenzyl chloride and requires a difficult separation stage.
Определение
ChEBI: A C-nitro compound that is nitrobenzene in which the hydrogen at position 4 is replaced by a chloromethyl group.
Общее описание
Solid.
Реакции воздуха и воды
May react slowly with water.
Профиль реактивности
Incompatible with sodium hydroxide. [EPA, 1998]. A halogenated aromatic nitro compound. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Угроза здоровью
Poisonous if swallowed or dust is inhaled.
Пожароопасность
Incompatible with sodium hydroxide.
Возможный контакт
A chloronitrobenzene compound, used
in organic synthesis.
