Product Description

Dimethylamine 40% aqueous solution (DMA40) is a versatile building block that is used in a wide variety of applications. We produces a range of high volume DMA based molecules like DMF and DMAC, DMAE, DMA-based dithiocarbamates.

For other applications we sell the DMA in the free market. We have identified over 100 different applications for DMA, in solvents, pharmaceuticals, agrochemicals, flocculents, surfactants, rubber chemicals, PU catalysts.

DMA is available in 2 forms :

  • as anhydrous liquified gas, DMA 100%
  • as aqueous solution, DMA 40 and 60%

We operate our own container fleet for DMA 100%, to guarantee a high quality service.

Dimethylamine is an extremely flammable product which should be stored in a well-ventilated area protected from fire risks (earthed tanks, no smoking, etc).

Delivery from containers and tankers should comply with our procedures which are available on request from our plant.

Both the gaseous product and the solutions are hazardous material. At a high airborne concentration the odour of ammonia predominates and dimethylamine acts as an asphyxiating gas.

At lower concentrations dimethylamine induces severe irritation and damage to the eyes and respiratory tract; skin contact causes burns.

The slightest leak is evident from the characteristic fishy odour, which is detectable at < 100 ppb by volume.

The storage area must be equipped with safety showers and eye baths whose locations should be familiar to the operators.

It is especially recommended that residues be burnt in an incinerator at > 800°C.
