PRODUCT INTRODUCTION

3-(Dimethylamino)propylamine (DMAPA) is a weakly basic, colorless liquid.

As an intermediate it is used for example for the sythesis of agro chemicals and surfactants.

DMAPA is used in water treatment chemicals and as catalyst for PU and Epoxy polymerisations.

The relative density was 0.8100. Boiling point 133 °c. Freezing point -70 °c. Below this temperature solidifies into a vitreous body. Flash point (closed cup) 15 °c. Refractive index 4350. Smoke and blacken in the air.
