Reaction Conditions:
in acetonitrile at 82; for 33 h;Menshutkin Reaction;Solvent;Temperature;
Steps:
there,We experimented by increasing the amount based on optimal choice of reagent. Tributylamine (100 g, 0.54 mol) was added to a 500 mL eggplant-shaped flask equipped with a reflux condenser,And acetonitrile (100 g) were added,here,1.1 equivalents (81.4 g, 0.6 mol equivalent)Of 1-bromobutane. Maintained at 82 ° C in an oil bath and reacted with stirring for 33 hours. The solution after reaction showed a slight yellow color. From this, acetonitrile was distilled off by an evaporator to obtain a pale orange solid. The solid was appropriately washed with suction filtration with ethyl acetate and dried. The yellow solution immediately after the reaction was analyzed by NMR,99.5% of tributylamine was reacting. Incidentally,0.5% of tributylamine remained.After washing with ethyl acetate, white tetrabutylammonium bromide was obtained.The yield of this was 98.9%The purity was 100%.
