Purification and preparation of butyramine
1 Reaction from DEA and polymethylene formaldehyde, N-methylene-2,6-di-dioletiline, then react with chloroacetyl chloride to form N- (2,6-di-ethylphenyl) -N-chlorineMethyl chloroacetamide is finally obtained with n-butanol to obtain butadena; the reaction is the same as the preparation process of the methylcramine, except that the raw materials are polymethylene and n-butanol; 2dea with chloroacetic acid, phosphorus phosphorusTo produce N- (2,6-diethylphenyl) chloroacetamide, polymethylene formaldehyde and hydrochloric acid, n-butanol, to form chloromethyl n-butyl ether, and then N- (2,6-diethylphenyl) chloroacetamide was bold to be bold under the presence of sodium hydroxide, and the finished product was separated. Method 2 Acetate inletation is a vinone, and the psychochloroma is generated by α-chloroacetyl chloride; aniline is introduced into two ethyl groups to an amino group adjacent to an amino group, and a carbon is formed with formaldehyde.Nitrogen double bond; the last two intermediates are added and the n-butyl alcohol is formed to form butrtutine.
