説明
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).
化学的特性
clear liquid. soluble in water and organic solvents.
使用
N,N-Dimethyl-1,3-propylenediamine is a useful catalyst for Knoevenagel condensation. It is also a useful hardening agent for expoxy resin.
調製方法
3-Dimethylaminopropylamine is produced by addition of dimethylamine to acrylonitrile and subsequent hydrogenation in the presence of ammonia.
一般的な説明
Dimethylaminopropylamine is a colorless liquid. (NTP, 1992)
空気と水の反応
Highly flammable. Temperature sensitive and possibly sensitive to air. Water soluble.
反応プロフィール
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.
火災危険
3-Dimethylaminopropylamine is flammable.
安全性プロファイル
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,.

毒性学
There are indications of contact and possibly respiratory allergy in relation to occupational exposure. Less than 0.9 ppm of 3-dimethylaminopropylamine in the workplace air may adversely affect respiratory function. The skin-sensitizing potential was verified in an animal study. In an oral 28-d study with rats (gavage, 7 times per week.), clinical symptoms including pulmonary and cardiac failure were noted at 250 mg kg
