3-Dimethylaminopropylamine Usage And Synthesis

Description

Dimethylaminopropylamine is an aliphatic amine present in amphoteric surfactants such as liquid soaps and shampoos. It is present as an impurity responsible for allergy from cocamidopropylbetaine. It is structurally similar to diethylaminopropylamine. It is also used as a curing agent for epoxy res ins and as an organic intermediate in chemical syntheses (ion exchangers, additives for flocculants, cosmetics and fuel additives, dyes and pesticides).

Chemical Properties

clear liquid

Uses

N,N-Dimethyl-1,3-propylenediamine is a useful catalyst for Knoevenagel condensation. It is also a useful hardening agent for expoxy resin.

Uses

3-(Dimethylamino)propylamine is an intermediate substance in the synthesis of alkylamidopropyldimethylamines/alkylamidobetaines; found as an impurity in cosmetic surfactants present in e.g. shampoos; hardener of epoxy resins; additive in fue!, dyes, pesticides and binding agents; in the production of ion-exchangers.

General Description

Colorless liquid.

Air & Water Reactions

Highly flammable. Temperature sensitive and possibly sensitive to air. Water soluble.

Reactivity Profile

3-Dimethylaminopropylamine neutralizes acids in exothermic reactions to form salts plus water. May be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. Flammable gaseous hydrogen may be generated in combination with strong reducing agents, such as hydrides.

Fire Hazard

3-Dimethylaminopropylamine is flammable.

Contact allergens

Dimethylaminopropylamine is an aliphatic amine present in amphoteric surfactants such as liquid soaps and shampoos. It is present as a residual impurity thought to be responsible for allergy from cocamidopropylbetaine. It is structurally similar to diethylaminopropylamine. It is also used as a curing agent for epoxy resins and an organic intermediate in chemical synthesises (ion exchangers, additives for flocculants, cosmetics and fuel additives, dyes and pesticides). Patch test has to be carefully interpreted, since the 1% aqueous solution has pH > 11 (personal observation).

Safety Profile

Moderately toxic by ingestion and skin contact. A skin and eye irritant. Very flammable when exposed to heat, flame, or oxidmers. Reaction with 1,2dichloroethane produces explosive acetylene gas. This and other amines igmte on contact with cellulose nitrate of hgh surface area. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits toxic fumes of NO,.
