Yield:-

Reaction Conditions:

in water at 20; for 0.5 h;Cooling with ice;

Steps:

1.1 Synthesis of bis (dimethylamine) methane

Under ice-cooling, 15 ml of 37 wt% aqueous formaldehyde solution was added to the reaction flask, And 50 ml of an aqueous solution of 33% by weight of dimethylamine hydrochloride was added dropwise with a dropping funnel. After completion of the dropwise addition, Stirred at room temperature for 30 min, then solid NaOH was added To the solution to form two phases, the separatory funnel is divided into two layers, dried with solid NaOH, placed in a filter, distilled at atmospheric pressure, collecting 83 ° C fractions,
