2-Aminoethanol solutions, ammonia

NO Absorption by Ammonia and 2-Aminoethanol Solutions. The best NO removal observed during the project occurred with concentrated aqueous ammonia (28 wt % NH3) as the scrubbing solution. Here 74% of the NO and 80% of the NO2 were absorbed. Table IV contains these results in addition to scrubbing data from a similar system, 2-aminoethanol. 

It is not necessary to isolate the di-w-butylaminoethyl bromide hydrobromide. The crude di-w-butylaminoethyl bromide hydrobromide prepared from 405 g. (2.34 moles) of di-w-butylaminoethanol is taken up in 600 cc. of water, and the tarry impurities are removed by extraction with three 200-cc. portions of benzene. About 400 cc. of water is evaporated from this solution, and to it is then added 2.8 1. of alcoholic ammonia prepared from absolute ethyl alcohol the concentration of the alcohol in the reaction mixture should be 90 per cent with respect to water. The yield is 114 g. (28 per cent of the theoretical amount based on 405 g. of the aminoethanol). The over-all yield obtained by the procedure described above is 27 per cent, based on the aminoethanol.
