Yield:128-04-1 99.85%

Reaction Conditions:

with sodium hydroxide at 25;Temperature;

Steps:

4
Take 1 mole of dimethylamine in an amount of 40%1.15 mol of 32% sodium hydroxide,The two-phase solution is passed through a Y-type mixer using a metering pump.And then take 1.1mol of carbon disulfide and the reaction solution and then metering pump through the Y-type mixer,And passed into a microreactor having a diameter of 6 mm at a flow rate of 60 mL / min. The residence time of the reaction solution in the microreactor was 10 seconds and the temperature was 25 ° C.The reaction solution was yellowishOr grass green transparent liquid that isSodium dimethyldithiocarbamate solution,After drying, sodium dimethyldithiocarbamate was obtained.Drying of the finished product by testing the melting point of 125.5 , the yield of 99.85%.
