Method of making:
Bis(dimethylaminoethyl) ether can be obtained by dehydrogenation of dimethylethanol and dimethylamino-2-chloroethane.

Features and uses:

Bis(dimethylaminoethyl) ether is one of the important amine catalysts in the polyurethane industry. Bis(dimethylaminoethyl) ether has extremely high catalytic activity and selectivity for the foaming reaction. The pure product has high activity. People use glycol to dilute it into a solution.

A-1 catalyst is a mixture of 70% bis(dimethylaminoethyl) ether and 30% dipropylene glycol (DPG) catalyst.

Purpose:
Bis(dimethylaminoethyl) ether is one of the important amine catalysts in the polyurethane industry. Bis(dimethylaminoethyl) ether has extremely high catalytic activity and selectivity for the foaming reaction. The pure product has high activity. People use glycol to dilute it into a solution.

Storage and transportation:

Should be sealed and stored in a dry, cool and ventilated warehouse

Packaging:

180KG/bucket Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the product performance from being mixed with other substances such as waterproof grade. Store in a cool, dry place, keep the container tightly closed, and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing. Maintain good hygiene habits.
