Description
COLOURLESS LIQUID.
1-methyltrimethylenediamine can be produced from crotonaldehyde by amination under hydrogenation conditions. Diamines with four to five carbon atoms are important intermediates for pharmaceuticals. However, the production of these diamines is restricted by the fact that the starting materials are difficult to obtain and that there is a strong tendency for cyclization during preparation.

Flammable. Gives off irritating or toxic fumes (or gases) in a fire. Above 52 °C explosive vapour/air mixtures may be formed.
Use water spray, foam, alcohol-resistant foam, dry powder, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.
Personal protection: chemical protection suit and filter respirator for organic gases and vapours adapted to the airborne concentration of the substance. Remove all ignition sources. Collect leaking and spilled liquid in covered containers as far as possible.
Fireproof. Separated from oxidants. Well closed.
A harmful concentration of airborne particles can be reached quickly on spraying.
The substance is corrosive to the eyes, skin and respiratory tract. Corrosive on ingestion.
NO open flames, NO sparks and NO smoking. Above 52 °C use a closed system, ventilation and explosion-proof electrical equipment.
STRICT HYGIENE!
Use ventilation, local exhaust or breathing protection.
Protective gloves. Protective clothing.
Wear face shield or eye protection in combination with breathing protection.
Drug Information
Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion.
Cough. Laboured breathing. Sore throat.
Redness. Pain. Skin burns.
Blurred vision. Severe deep burns.
