N-烷基化芳族胺是通过在150 ℃-280 ℃的温度下，在0.01 - 1.0摩尔磷酸/氮当量的存在下，将芳族胺与低级脂族醇一起加热而制备的。此后，分离形成的液相以分离N-烷基化芳族胺。
N-alkylated aromatic amines are prepared by heating an aromatic amine together with a lower aliphatic alcohol in the presence of from 0.01 to 1.0 mol of phosphoric acid per nitrogen equivalent at a temperature in the range of from 150 DEG -280 DEG C. Thereafter, the liquid phases that form are separated to isolate the N-alkylated aromatic amine.
