Benzyldimethylamine is a chemical compound from the group of amino compounds.

Production and representation

Benzyldimethylamine as a catalyst can be obtained by reaction of benzylamine with methanol in the presence of hydrogen chloride.

The presentation by the reaction of benzyl chloride with dimethylamine is possible.

Properties

Benzyldimethylamine is an inflammatory, low volatile, colorless liquid with an amine-like fetid odor, which is sparingly soluble in water. Its aqueous solution is alkaline. It has at 20 ° C has a viscosity of 3 mPa · s

Use

Benzyldimethylamine is used to produce polyurethane coatings, coatings, foams and casting compositions and used as an intermediate in organic syntheses. It continues to serve in electron microscopy as so-called Maraglas catalyst.

Safety

The vapors of benzyl dimethyl amine can form (55 ° C, ignition temperature 410 ° C flash point) with air to form an explosive mixture.
