Химические свойства

PINK TO BROWN FINE CRYSTALLINE POWDER

Использование

Intermediate in the manufacture of azo dyes, pharmaceuticals.

Общее описание

White or slightly reddish solid.

Реакции воздуха и воды

Slightly soluble in water.

Профиль реактивности

Amines are chemical bases. They neutralize acids to form salts plus water. These acid-base reactions are exothermic. The amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. Amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.

Опасность

Moderate toxicity by ingestion.

Пожароопасность

Flash point data are not available for 4'-Aminoacetanilide, but 4'-Aminoacetanilide is probably combustible.
