Ethanol → 1-Propanaminium, N,N-dimethyl-N-propyl-, hydroxide (1:1)

Participants

Reaction Steps

15 ml of dipropylamine in 50 ml of ethanol as a solvent and with KHCO3 as a buffer are reacted with 20 ml of methyl iodide at a temperature of from 40 to 50° C. in a water bath with stirring. After 2 hours, cooling to room temperature was effected, the product dimethyldipropylammonium iodide crystallizing out. The solid filtrate was washed in ethanol. An aqueous solution of the iodide was converted over an Amberlyst anion exchanger into dimethyldipropylammonium hydroxide.
