N-(3-Aminopropyl)morpholine Chemical Properties,Usage,Production

Chemical Properties

Clear liquid

Uses

Fiber synthesis; chemical intermediate.

Uses

3-(4-Morpholinyl)propylamine is catalytic agent, petrochemical additive. It is an important raw material and intermediate used in organic synthesis, pharmaceuticals, agrochemicals and dyestuffs.

Definition

ChEBI: A member of the class of morpholines that is morpholine substituted by a 3-aminopropyl group a the N atom.

General Description

A colorless liquid with a faint, fishlike odor. Burns, but requires some effort to ignite. Corrosive to tissue. Produces toxic oxides of nitrogen during combustion.

Air & Water Reactions

Soluble in water.

Reactivity Profile

N-(3-Aminopropyl)morpholine behaves as an amine. 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

Strongly irritant to tissue.

Health Hazard

TOXIC; inhalation, ingestion or skin contact with material may cause severe injury or death. Contact with molten substance may cause severe burns to skin and eyes. Avoid any skin contact. Effects of contact or inhalation may be delayed. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution.

Fire Hazard

Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes. Some are oxidizers and may ignite combustibles (wood, paper, oil, clothing, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated.

Safety Profile

A corrosive material. Moderately toxic by several routes. A severe skin and eye irritant. Combustible. Can react with oxidizing materials. To fight fire, use alcohol foam, dry chemical. When heated to decomposition it emits toxic fumes of NOx,.
