Beschreibung

3,3'-Dihydroxybenzidine is an organic synthesis intermediate used as a raw material for the synthesis of fire-resistant polymers (polyhydroxyamino acids).3,3'-Dihydroxybenzidine is also used in the preparation of hydroxyl-containing polyimides, all of which are synthesised to be soluble in NMP when heated. 3,3'-Dihydroxybenzidine is used in the synthesis of polyimides with hydroxyl groups. The glass transition temperature (Tg) of polyimides ranges from 336-360°C, independent of the structure of the tetracarboxylic dianhydride. The storage modulus of some polyimides does not decrease at elevated temperatures. All polyimides thermally transform into polybenzoxazole when heated to 500°C for 1 hour under vacuum.

Chemische Eigenschaften

A pale brown solid

Verwenden

4,4'-diaminobiphenyl-3,3'-diol is used as organic intermediates.

Allgemeine Beschreibung

Colorless crystals.

Air & Water Reaktionen

Keep well closed. Protect from air and light.

Reaktivit?t anzeigen

3,3'-Dihydroxybenzidine is an aminoalcohol. 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.

Health Hazard

ACUTE/CHRONIC HAZARDS: When heated to decomposition 3,3'-Dihydroxybenzidine emits toxic fumes.

Sicherheitsprofil

Suspected carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Mutation data reported. When heated to decomposition it emits toxic fumes of Nox
