Versuchsvorschrift

A series of di-n-butyl ammonium salts were prepared utilizing an absolute ethanol solution of di-N-butylamine. In preparing di-n-butylammonium bromide, hydrogen bromide gas was introduced into a solution of 585 grams of di-n-butylamine in absolute ethanol until the solution was saturated. The reaction vessel was in an ice bath during the addition. The solution was then treated with ether followed by further cooling to induce crystallization. The product was isolated by filtration, washed thoroughly with ether, and dried for about 12 hours in a vacuum oven (80° C. at about 15 torr). There was obtained an 83.7% yield of di-n-butylammonium bromide, MP 295°-296.5° C.
