| titleOfInvention | Process for separating alkylamines from ammonia and other gases |
| abstract | Methyl- or ethyl-amines are separated from a mixture with ammonia and other gases, such as results from the catalytic interaction of methyl or ethyl alcohol with ammonia, by passing the mixture through solid ammonium chloride bathed in methyl or ethyl alcohol. The ammonium chloride is contained in a tower or towers, beneath which the alcohol is boiled and above which is a reflux condenser. In the case of the ethylamines, the mono-, di-, and tri-bodies react with the ammonium chloride with evolution of ammonia to form the corresponding hydrochlorides, which dissolve in the alcohol and are separated by liberating the bases and fractionally distilling them. Of the methylamines, the tri-body is not affected by the treatment and issues from the tower with the residual gases and is removed therefrom by compression and cooling; the mono- and di-bodies dissolve in the methyl alcohol and are separated by allowing the hydrochloride of the monomethylamine to crystallize out and evaporation of the filtrate to obtain the dimethylamine hydrochloride. |
