N,N’-Dimethyl-1,3-propanediamine (abbreviated DMAPA) is a colorless liquid with an irritating odor.
Appearance: DMAPA is a colourless liquid, which can be evaporated to vapour at room temperature.
Solubility: DMAPA is soluble in water, alcohol and ether solvents.
Stability: DMAPA is relatively stable at room temperature, it is strongly alkaline and will decompose when encountering acid, generating toxic gases.
Uses:
Catalyst: DMAPA is often used as catalyst and cross-linking agent to promote polymerisation and cross-linking reactions.
Surfactant: DMAPA can be used as a component of some surfactants to regulate surface tension.
Method of Preparation:
DMAPA can be synthesised by methylation of 1,3-propanediamine with methanol. The reaction is usually carried out in an inert atmosphere, such as a nitrogen atmosphere.
Safety Information:
DMAPA has a pungent odour and may cause irritation to the eyes, skin and respiratory tract; appropriate protective equipment should be worn during use.
The compound is strongly basic, avoid contact with acids as this may cause violent reactions.
DMAPA needs to be stored in a cool, dry and well-ventilated place away from sources of ignition and flammable substances.
