2-Amino-2-methyl-1-propanol Usage And Synthesis

Chemical Properties

white crystals or viscous liquid

Uses

2-Amino-2-methylpropanol is used for the preparation of buffer solutions, suitable for the determination of alkaline phosphatase.

General Description

A clear light colored liquid. Insoluble in water and about the same density as water. Flash point 172°F. Used to make other chemicals.

Air & Water Reactions

Insoluble in water.

Reactivity Profile

2-Amino-2-methyl-1-propanol 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.

Hazard

Toxic by ingestion.

Health Hazard

Causes severe irritation. Inhalation may be fatal as a result of spasm, inflammation, and edema of laryns and bronchi, chemical pneumonitis, and pulmonary edema. Symptoms of exposure may include burning sensation, coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

Fire Hazard

Special Hazards of Combustion Products: Emits toxic fumes during fire conditions.

Purification Methods

Purify it by distilling and fractional freezing. The hydrochloride has m 204o-206o. [Beilstein 4 III 783, 4 IV 1740.]
